Recommended victories: Domination, Diplomatic

Victory: Domination

Overall: The UA is very effective, as adjacent units will be weaker. Its effectiveness will increase if you advance to a later era. Therefore, a scientific focus is also recommended. In the end, adjacent units will be 30% weaker.
The UU can be produced quickly and can easily resist ranged attacks. This should make it easier to capture Cities and defeat your enemies. These units should form the bulk of your army.
Use the second element of the UA (increase influence per turn with afraid cities) to ally militaristic city states so they will occasionally gift you units.
The UB may give you more faith. If you have a strong faith income, you may want to choose Holy Warriors (belief) to buy pre-industrial units with Faith.

Recommended Policy tree(s): Honor is recommended for obvious reasons. You could also choose Piety to get a Reformation belief. Choose Religious Fervor to purchase Industrial era (and later) units with Faith. Other possible choices are Heathen Conversion and Charitable Missions.

Recommended Ideology: Autocracy, as most of the tenets are beneficial for your army.

Victory: Diplomatic

Overall: The second element of the UA can be very effective as long as you have a strong army. You need to scare City States to make them your allies. First, get a considerable army. If you place units adjacent to their borders you'll scare them for sure. If they are "afraid", your influence will increase by 3 points per turn. They usually don't become afraid if you don't place units next to their borders.

Recommended Policy tree(s): Patronage. For obivous reasons. This tree will make it easier to ally city states.

Recommended Ideology: Freedom.
- Covert Action: Spies have double the chance to successfully rig City-State elections.
- Arsenal of Democracy: +25% Production towards Military Units. Gain 20 Influence from each Military Unit gift to City-States.
- Treaty Organization: Gain 4 more Influence per turn with City-States you have a trade route with.
