"A preview of a project I'm working on alongside Beyond Typus, Part 3.

The 3rd new bookmark of 7: Timur the Lame (2nd of July 1387)

Last week About a 1½ weeks ago, I talked about the final 7 institutions of the 1X planned. This week, I'll go to the other end, and talk about the first 4. All 4 will have already spawned before the earliest start, just like Feudalism in vanilla, but will allow a better distinction between different levels of advancement in different areas for the earlier start dates.

Agriculture
The development of planting and harvesting food, as opposed to hunter-gatherer or exclusively pastoral societies.
-Present in nearly the entire world at start, only lacking in a few very remote & poor areas.

Literacy
The development of reading & writting, conveying information of at least a moderately complex meaning in a standised way.
-Allows the Clergy estate. Present in nearly all the Old World, and parts of the New World.

Feudalism
The development of hierarchical structures of a feudal (or analogous) nature, including multi-tiered levels of vassalage or obligation such as caste systems or serfdoms.
-Allows the Nobles estate. Present in the majority of moderately advanced societies.

Guilds
The development of like-minded professionals forming organisations to advance shared interests in the context of societies advanced enough to possess specialisation of labour.
-Allows the Burgher estate. Present in only the richer parts of the Old World (Europe, North Africa, Middle East-Persia, India, South Asia & East Asia) and perhaps even Mesoamerica.

(Note the estate interactions are all theory, and dependent on how Paradox changes estates in 1.26)"
