How does the Culture Points system affect progression in Travian?

11 Eki 19:45

In Travian, culture points are earned by completing certain actions like building structures, researching technologies, and winning battles. I'm trying to understand how these points influence a player's progression and access to new features. Do they primarily unlock higher-level buildings, affect alliance ranking, or serve another purpose? How have you seen culture points shape long-term strategies in your games? Looking for a clear overview.
