革新代表一种文化在科技、法律和思想上的进步。Once an innovation is unlocked it can be used by any County and Character of the culture which unlocked it. Innovations are grouped into 3 unlock categories: Military and Civic, Cultural, and Regional.
- Military and Civic innovations have a small chance to progress towards being unlocked each month based on multiple factors, the most important being average Development in Counties of one Culture. The second most important factor is the number of neighbor Counties that belong to a Culture which already unlocked an innovation not shared.
- Regional innovations are unlocked when the Culture is present enough in a certain Region and remain unlocked even if said territory is lost.
- Cultural innovations are always active but require a certain Culture.
时代
Each Culture will be within one of 4 Eras which determine which innovations the Culture can unlock.
Once at least 50% of the innovations of an Era are unlocked and the required minimum year is reached the Culture will slowly progress to the next Era based on the average 
Development in the Culture's Counties.
A culture cannot progress to another Era if its Cultural Head is Tribal.
