Senate

Politics and government play a vital role in the development of your society. As such, a Senate, being where the ruling class may confer with its subjects, is a vital part of your civilian infrastructure.

First introduced in Thrones & Patriots, the Senate allows a nation to research Governments and it also creates the Patriot unit, a special General with additional abilities. A nation may built the Senate only once and building it in any city, other than the current Capital, will make that city the new capital. If a nation's Senate is destroyed or captured, it is allowed to create a new one.

Nation-specific

The Americans research Governments for free.
The Iroquois build their first Senate instantly and for free.
The Persians have two capitals. The city where the Senate is built becomes the second capital alongside their first city. If the Senate is built in the first city, then the next city to be built or aqcuired will become the second capital.

Trivia

Although most nations may built the Senate only once, it is possible to capture and keep Senates from enemy nations (although the captured city with the Senate will NOT become a capital).
If you happen to have captured multiple cities with Senates, all Senate buildings must be dismantled before you can build another new one to move your capital.
