Sengoku Jidai

The Sengoku Jidai is the period in Japanese history in which civil wars and social upheavals took place almost continuously in the 15th and 16th centuries. Though the Ōnin War (1467) is generally chosen as the Sengoku period's start date, there are many competing historiographies for its end date, ranging from 1568, the date of Oda Nobunaga's march on Kyoto, to the suppression of the Shimabara Rebellion in 1638, deep into what is traditionally considered the Edo period. Regardless of the dates chosen, the Sengoku period overlaps substantially with the Muromachi period (1336–1573).

The Sengoku period was initiated by the Ōnin War in 1467 which collapsed the feudal system of Japan under the Ashikaga shogunate. Various samurai warlords and clans fought for control of Japan in the power vacuum, while the Ikkō-ikki emerged to fight against samurai rule. The arrival of Europeans in 1543 introduced the arquebus into Japanese warfare. Japan ended its mission to Ming China in 1547, which had been carried out 19 times since 1401 due to the need for trade. Oda Nobunaga dissolved the Ashikaga shogunate in 1573 and launched a war of political unification by force, including the Ishiyama Hongan-ji War, until his death in the Honnō-ji Incident in 1582. Nobunaga's successor Toyotomi Hideyoshi completed his campaign to unify Japan and consolidated his rule with numerous influential reforms. Hideyoshi launched the Japanese invasions of Korea in 1592, but their eventual failure damaged his prestige before his death in 1598. Tokugawa Ieyasu displaced Hideyoshi's young son and successor Toyotomi Hideyori at the Battle of Sekigahara in 1600 and re-established the feudal system under the Tokugawa shogunate.

The Sengoku period was named by Japanese historians after the similar but otherwise unrelated Warring States period of China. Modern Japan recognizes Oda Nobunaga, Toyotomi Hideyoshi, and Tokugawa Ieyasu as the three "Great Unifiers" for their restoration of central government in the country.

War between the Azuchi-Momoyama Period and Joseon Korea

The Imjin War, involved two separate yet linked invasions: an initial invasion in 1592, a brief truce in 1596, and a second invasion in 1597. The conflict ended in 1598 with the withdrawal of Japanese forces from the Korean Peninsula after a military stalemate in Korea's southern provinces.

The invasions were launched by Toyotomi Hideyoshi with the intent of conquering the Korean Peninsula and China proper, which were ruled by the Joseon and Ming dynasties, respectively. Japan quickly succeeded in occupying large portions of the Korean Peninsula, but the contribution of reinforcements by the Ming, as well as the disruption of Japanese supply fleets along the western and southern coasts by the Joseon navy, forced the Japanese forces to withdraw from Pyongyang and the northern provinces. Afterwards, with righteous armies (Joseon civilian militias) conducting guerrilla warfare against the occupying Japanese forces and supply difficulties hampering both sides, neither force was able to mount a successful offensive or gain any additional territory, resulting in a military stalemate. The first phase of the invasion ended in 1596, and was followed afterwards by ultimately unsuccessful peace negotiations between Japan and the Ming.

In 1597, Japan renewed its offensive by invading Korea a second time. The pattern of the second invasion largely mirrored that of the first. The Japanese had initial successes on land, capturing several cities and fortresses, only to be halted and forced to withdraw to the southern coastal regions of the peninsula. However, the pursuing Ming and Joseon forces were unable to dislodge the Japanese from these positions, where both sides again became locked in a ten-month-long military stalemate.

With Toyotomi Hideyoshi's death in 1598, limited progress on land, and continued disruption of supply lines by the Joseon navy, the Japanese forces in Korea were ordered to withdraw back to Japan by the new governing Council of Five Elders. Final peace negotiations between the parties followed, and continued for several years, ultimately resulting in the normalization of relations. The Japanese invasions of Korea at the time were the largest seaborne invasions in history, with the Japanese committing over 300,000 men to the campaigns.

Sino-Korean War (1636-1637)

The Qing invasion of Joseon occurred in the winter of 1636 when the newly established Qing dynasty invaded the Joseon dynasty, establishing the former's status as the hegemon in the Imperial Chinese Tributary System and formally severing Joseon's relationship with the Ming dynasty. The invasion was preceded by the Later Jin invasion of Joseon in 1627.

The invasion resulted in a Qing victory. Joseon was forced to establish a tributary relationship with the Qing Empire, as well as cut ties with the declining Ming. The crown prince of Joseon along with his younger brother were taken as hostages, but they came back to Joseon after a few years. One of the two later became the King Hyojong. He is best known for his plan for an expedition to the Qing dynasty.

Shimabara Rebellion

The Shimabara Rebellion (島原の乱, Shimabara no ran), also known as the Shimabara-Amakusa Rebellion (島原･天草の乱, Shimabara-Amakusa no ran) or Shimabara-Amakusa Ikki (島原･天草一揆), was an uprising that occurred in the Shimabara Domain of the Tokugawa Shogunate in Japan from 17 December 1637 to 15 April 1638.

Matsukura Katsuie, the daimyō of the Shimabara Domain, enforced unpopular policies set by his father Matsukura Shigemasa that drastically raised taxes to construct the new Shimabara Castle and violently prohibited Christianity. In December 1637, an alliance of local rōnin and mostly Catholic peasants led by Amakusa Shirō rebelled against the Tokugawa shogunate due to discontent over Katsuie's policies. The Tokugawa Shogunate sent a force of over 125,000 troops supported by the Dutch to suppress the rebels and defeated them after a lengthy siege against their stronghold at Hara Castle in Minamishimabara.

Following the successful suppression of the rebellion, Shirō and an estimated 37,000 rebels and sympathizers were executed by beheading, and the Portuguese traders suspected of helping them were expelled from Japan. Katsuie was investigated for misruling, and was eventually beheaded in Edo, becoming the only daimyō to be executed during the Edo period. The Shimabara Domain was given to Kōriki Tadafusa. Japan's policies of national seclusion and persecution of Christianity were tightened until the Bakumatsu in the 1850s.

Shimabara Rebellion is often portrayed as a Christian rebellion against violent suppression by Matsukura Katsuie. However the main academic understanding is that the rebellion was mainly against Matsukura's misgovernance by peasants, with Christians later joining the rebellion.

The Shimabara Rebellion was the largest civil conflict in Japan during the Edo period, and was one of only a handful of instances of serious unrest during the relatively peaceful period of the Tokugawa shogunate's rule. The Shimabara Rebellion was the last large-scale armed clash in Japan until the outbreak of the final rebellion, the Boshin War, in 1868, leading to the destruction of the Tokugawa Shogunate.

Bayinnaung's Campaign

Bayinnaung Kyawhtin Nawrahta (16 January 1516 – 10 October 1581) was king of the Toungoo Dynasty of Myanmar from 1550 to 1581. During his 31-year reign, which has been called the "greatest explosion of human energy ever seen in Burma", Bayinnaung assembled what was most likely the largest empire in the history of Southeast Asia, which included much of modern-day Burma, the Chinese Shan states, Lan Na, Lan Xang, Manipur and Siam.

Although he is best remembered for his empire building, Bayinnaung's greatest legacy was his integration of the Shan states into the Irrawaddy Valley-based kingdoms. After the conquest of the Shan states in 1557–1563, the king put in an administrative system that reduced the power of hereditary Shan saophas, and brought Shan customs in line with lowland norms. It eliminated the threat of Shan raids into Upper Burma, an overhanging concern since the late 13th century. His Shan policy was followed by Burmese kings right up to the final fall of the kingdom to the British in 1885.

Bayinnaung could not replicate this administrative policy everywhere in his far-flung empire, however. His empire was a loose collection of formerly sovereign kingdoms, whose kings were loyal to him as the Cakkavatti ("Universal Ruler"), rather than to the Kingdom of Toungoo itself. Indeed, Ava and Siam revolted just over two years after his death. By 1599, all the vassal states had revolted, and the Toungoo Empire completely collapsed.

Bayinnaung is considered one of the three greatest kings of Burma, along with Anawrahta and Alaungpaya. Some of the most prominent places in modern Myanmar are named after him. He is also well known in Thailand as the Phra Chao Chana Sip Thit (พระเจ้าชนะสิบทิศ, "Conqueror of the Ten Directions").

Joan of Arc's Campaign

Joan of Arc (1412 – 30 May 1431) is a patron saint of France, honored as a defender of the French nation for her role in the siege of Orléans and her insistence on the coronation of Charles VII of France during the Hundred Years' War. Claiming to be acting under divine guidance, she became a military leader who transcended gender roles and gained recognition as a savior of France.

Joan was born to a propertied peasant family at Domrémy in northeast France. In 1428, she requested to be taken to Charles, later testifying that she was guided by visions from the archangel Michael, Saint Margaret, and Saint Catherine to help him save France from English domination. Convinced of her devotion and purity, Charles sent Joan, who was about seventeen years old, to the siege of Orléans as part of a relief army. She arrived at the city in April 1429, wielding her banner and bringing hope to the demoralized French army. Nine days after her arrival, the English abandoned the siege. Joan encouraged the French to aggressively pursue the English during the Loire Campaign, which culminated in another decisive victory at Patay, opening the way for the French army to advance on Reims unopposed, where Charles was crowned as the King of France with Joan at his side. These victories boosted French morale, paving the way for their final triumph in the Hundred Years' War several decades later.

After Charles's coronation, Joan participated in the unsuccessful siege of Paris in September 1429 and the failed siege of La Charité in November. Her role in these defeats reduced the court's faith in her. In early 1430, Joan organized a company of volunteers to relieve Compiègne, which had been besieged by the Burgundians—French allies of the English. She was captured by Burgundian troops on 23 May. After trying unsuccessfully to escape, she was handed to the English in November. She was put on trial by Bishop Pierre Cauchon on accusations of heresy, which included blaspheming by wearing men's clothes, acting upon visions that were demonic, and refusing to submit her words and deeds to the judgment of the church. She was declared guilty and burned at the stake on 30 May 1431, aged about nineteen.

In 1456, an inquisitorial court reinvestigated Joan's trial and overturned the verdict, declaring that it was tainted by deceit and procedural errors. Joan has been revered as a martyr, and viewed as an obedient daughter of the Roman Catholic Church, an early feminist, and a symbol of freedom and independence. After the French Revolution, she became a national symbol of France. In 1920, Joan of Arc was canonized by the Roman Catholic Church and, two years later, was declared one of the patron saints of France. She is portrayed in numerous cultural works, including literature, music, paintings, sculptures, and theater.

Hundred Years War (1415-1453 AD)

Italian Wars

The Italian Wars were a series of conflicts fought between 1494 and 1559, mostly in the Italian Peninsula, but later expanding into Flanders, the Rhineland and Mediterranean Sea. The primary belligerents were the Valois kings of France, and their Habsburg opponents in the Holy Roman Empire and Spain. At different points, various Italian states participated in the war, some on both sides, with limited involvement from England and the Ottoman Empire.

The Italic League established in 1454 achieved a balance of power in Italy, but fell apart after the death of its chief architect, Lorenzo de' Medici, in 1492. Combined with the ambition of Ludovico Sforza, its collapse allowed Charles VIII of France to invade Naples in 1494, which drew in Spain and the Holy Roman Empire. Although Charles was forced to withdraw in 1495, ongoing political divisions among the Italian states made them a battleground in the struggle for European domination between France and the Habsburgs.

Fought with considerable brutality, the wars took place against the background of religious turmoil caused by the Reformation, particularly in France and the Holy Roman Empire. They are seen as a turning point in the evolution from medieval to modern warfare, with the use of the arquebus or handgun becoming common, along with significant technological improvements in siege artillery. Literate commanders and modern printing methods also make them one of the first conflicts with a significant number of contemporary accounts, including those of Francesco Guicciardini, Niccolò Machiavelli and Blaise de Montluc.

After 1503, most of the fighting was initiated by French invasions of Lombardy and Piedmont, but although able to hold territory for periods of time, they could not do so permanently. By 1557, the growth of Protestantism meant the major belligerents faced internal conflict over religion, forcing them to refocus on domestic affairs. This led to the Treaty of Cateau-Cambrésis (1559), under which France was largely expelled from Italy, but in exchange gained Calais from England, and the Three Bishoprics from Lorraine. In turn, Spain acquired sovereignty over the Kingdom of Naples and Kingdom of Sicily in Southern Italy, as well the Duchy of Milan in Northern Italy.

Valois' War for the Conquest of Italy

Fall of Constantinople

The fall of Constantinople, also known as the conquest of Constantinople, was the capture of the capital of the Byzantine Empire by the Ottoman Empire. The city was captured on 29 May 1453 as part of the culmination of a 53-day siege which had begun on 6 April.

The attacking Ottoman Army, which significantly outnumbered Constantinople's defenders, was commanded by the 21-year-old Sultan Mehmed II (later nicknamed "the Conqueror"), while the Byzantine army was led by Emperor Constantine XI Palaiologos. After conquering the city, Mehmed II made Constantinople the new Ottoman capital, replacing Adrianople.

The conquest of Constantinople and the fall of the Byzantine Empire was a watershed of the Late Middle Ages, marking the effective end of the last remains of the Roman Empire, a state which began in roughly 27 BC and had lasted nearly 1500 years. Among many modern historians, the fall of Constantinople is considered the end of the medieval period. The city's fall also stood as a turning point in military history. Since ancient times, cities and castles had depended upon ramparts and walls to repel invaders. The Walls of Constantinople, especially the Theodosian Walls, were some of the most advanced defensive systems in the world at the time. For 800 years, the Theodosian Walls, regarded by historians as the strongest and most fortified walls in the ancient and medieval era, protected Constantinople from attack. However, these fortifications were overcome with the use of gunpowder, specifically from Ottoman cannons and bombards, heralding a change in siege warfare. The Ottoman cannons repeatedly fired massive cannon balls weighing 500 kilograms (1,100 lb) over 1.5 kilometres (0.93 mi) which created gaps in the Theodosian Walls for the Ottoman siege.

The war transformed the Ottoman Empire from a realm at the margins of the Islamic world, mainly located in Anatolia and the Balkans, to a huge empire encompassing much of the traditional lands of Islam, including the cities of Mecca, Cairo, Damascus, and Aleppo. Despite this expansion, the seat of the empire's political power remained in Constantinople.

The Ottoman–Safavid War of 1623–1639 was the last of a series of conflicts fought between the Ottoman Empire and Safavid Iran, then the two major powers of Western Asia, over control of Mesopotamia. After initial Persian success in recapturing Baghdad and most of modern Iraq, having lost it for 90 years, the war became a stalemate as the Persians were unable to press further into the Ottoman Empire, and the Ottomans themselves were distracted by wars in Europe and weakened by internal turmoil. Eventually, the Ottomans were able to recover Baghdad, taking heavy losses in the final siege, and the signing of the Treaty of Zuhab ended the war in an Ottoman victory. Roughly speaking, the treaty restored the borders of 1555, with the Safavids keeping Daghestan, Shirvan, eastern Georgia, and Eastern Armenia, while western Georgia and Western Armenia decisively came under Ottoman rule. The eastern part of Samtskhe (Meskheti) was irrevocably lost to the Ottomans as well as Mesopotamia. Although parts of Mesopotamia were briefly retaken by the Iranians later on in history, notably during the reigns of Nader Shah (1736–1747) and Karim Khan Zand (1751–1779), it remained thenceforth in Ottoman hands until the aftermath of World War I.

The Battle of Mohács was fought on 29 August 1526 near Mohács, Kingdom of Hungary, between the forces of the Kingdom of Hungary and its allies, led by Louis II, and those of the Ottoman Empire, led by Suleiman the Magnificent. The Ottoman victory led to the partition of Hungary for several centuries between the Ottoman Empire, the Habsburg monarchy, and the Principality of Transylvania. Further, the death of Louis II as he fled the battle marked the end of the Jagiellonian dynasty in Hungary and Bohemia, whose dynastic claims passed to the House of Habsburg.

Thirty Years' War

The Thirty Years' War was one of the longest and most destructive conflicts in European history, lasting from 1618 to 1648. Fought primarily in Central Europe, an estimated 4.5 to 8 million soldiers and civilians died as a result of battle, famine, and disease, while some areas of modern Germany experienced population declines of over 50%. Related conflicts include the Eighty Years' War, the War of the Mantuan Succession, the Franco-Spanish War, the Torstenson War, the Dutch-Portuguese War and the Portuguese Restoration War.

The war was traditionally viewed as a continuation of the religious conflict initiated by the 16th-century Reformation within the Holy Roman Empire. The 1555 Peace of Augsburg attempted to resolve this by dividing the Empire into Lutheran and Catholic states, but over the next 50 years the expansion of Protestantism beyond these boundaries destabilised the settlement. However, while modern commentators accept differences over religion and Imperial authority were important factors in causing the war, they argue its scope and extent were driven by the contest for European dominance between Habsburg-ruled Spain and Austria, and the French House of Bourbon.

Its outbreak is generally traced to 1618, when Emperor Ferdinand II was deposed as king of Bohemia and replaced by the Protestant Frederick V of the Palatinate. Although Imperial forces quickly suppressed the Bohemian Revolt, his participation expanded the fighting into the Palatinate, whose strategic importance drew in the Dutch Republic and Spain, then engaged in the Eighty Years' War. Rulers like Christian IV of Denmark and Gustavus Adolphus of Sweden also held territories within the Empire, giving them and other foreign powers an excuse to intervene. The result was to turn an internal dynastic dispute into a broader European conflict.

The first phase from 1618 until 1635 was primarily a civil war between German members of the Holy Roman Empire, with support from external powers. After 1635, the Empire became one theatre in a wider struggle between France, supported by Sweden, and Emperor Ferdinand III, allied with Spain. This concluded with the 1648 Peace of Westphalia, whose provisions included greater autonomy within the Empire for states like Bavaria and Saxony, as well as acceptance of Dutch independence by Spain. The conflict shifted the balance of power in favour of France, and set the stage for the expansionist wars of Louis XIV which dominated Europe for the next sixty years.

Thirty Years' War

Lepanto Campaign

Note: This scenario is an excerpt from the one from Age of Empires II: The Conquerors.

The Battle of Lepanto was a naval engagement that took place on 7 October 1571 when a fleet of the Holy League, a coalition of Catholic states arranged by Pope Pius V (comprising Spain and its Italian territories, several independent Italian states, and the Sovereign Military Order of Malta), inflicted a major defeat on the fleet of the Ottoman Empire in the Gulf of Patras. The Ottoman forces were sailing westward from their naval station in Lepanto (the Venetian name of ancient Naupactus – Greek Ναύπακτος, Turkish İnebahtı) when they met the fleet of the Holy League which was sailing east from Messina, Sicily.

The fleet of the Holy League consisted of 109 galleys and 6 galleasses from the Republic of Venice, 49 galleys from the Spanish Empire, 27 galleys from the Republic of Genoa, 7 galleys from the Papal States, 5 galleys from the Order of Saint Stephen and the Grand Duchy of Tuscany, 3 galleys from the Duchy of Savoy, 3 galleys from the Knights of Malta and some private ships. Don John of Austria, half-brother of Philip II of Spain, was named by Pope Pius V as overall commander of the fleet and led the centre division along with the Papal captain Marcantonio Colonna and the Venetian Sebastiano Venier; the wings were commanded by the Venetian Agostino Barbarigo and the Genoese Gianandrea Doria. The Ottoman fleet consisted of 222 galleys and 56 galliots and was led by Müezzinzade Ali Pasha, Mahomet Sirocco and Occhiali.

In the history of naval warfare, Lepanto marks the last major engagement in the Western world to be fought almost entirely between rowing vessels, namely the galleys and galleasses which were the direct descendants of ancient trireme warships. The battle was in essence an "infantry battle on floating platforms". It was the largest naval battle in Western history since classical antiquity, involving more than 400 warships. Over the following decades, the increasing importance of the galleon and the line of battle tactic would displace the galley as the major warship of its era, marking the beginning of the "Age of Sail".

The victory of the Holy League is of great importance in the history of Europe and of the Ottoman Empire, marking the turning-point of Ottoman military expansion into the Mediterranean, although the Ottoman wars in Europe would continue for another century. It has long been compared to the Battle of Salamis, both for tactical parallels and for its crucial importance in the defense of Europe against imperial expansion. It was also of great symbolic importance in a period when Europe was torn by its own wars of religion following the Protestant Reformation. Pope Pius V instituted the feast of Our Lady of Victory, and Philip II of Spain used the victory to strengthen his position as the "Most Catholic King" and defender of Christendom against Muslim incursion.

End of the Turkic presence in Russia

The Great Stand on the Ugra River (Russian: Великое стояние на Угре) or the Standing on the Ugra River, also known as the Battle of the Ugra, was a standoff in 1480 on the banks of the Ugra River between the forces of Akhmat Khan of the Great Horde, and Grand Prince Ivan III of the Grand Duchy of Moscow.

After Ivan III stopped paying tribute to the Horde, Akhmat Khan led an army towards Moscow, leading to a standoff between the two armies on the banks of the river. Akhmat Khan waited for his Lithuanian reinforcements to arrive, but they never did, with one Mongol attempt to cross the river failing due to Russian fire, leading to Akhmat Khan to retreat. Both armies departed after little fighting.

In Russian historiography, it has been interpreted as the end of the "Tatar yoke" in Russia, though some historians believe that the event itself was insignificant and did not change Russo-Tatar relations. Nevertheless, the event is usually regarded as the end of nominal Tatar suzerainty over Russia.
