Republics

The Senate view

The Senate

主条目：Politics

The Senate, in a republic, has 100 seats, and each seat belongs to one of five factions. Every adult character in a republic has a predilection to each faction, and is supportive of one. Each faction has a leader, generally the most prominent character that supports that faction.

Depending on which faction the ruler of the republic belongs to, the republic gets various bonuses or maluses. The amount of seats in the senate changes over time, depending on different factors, with the charisma of the faction leader always impacting the attraction of the seats. If a nation wishes to instantly strengthen a faction's position in the senate, it can spend oratory power to convince 10 seats to join that faction. Doing so however, results in an increase of tyranny.

Civic	+25% tax income, -10% building cost, -10% building construction speed
Military	+25% land morale, +25% naval morale
Mercantile	+25% commerce income, +5 diplomatic reputation

Actions

There are three different categories of actions which require senate approval:

• All changing of laws require approval by the senate
• A lot of character interactions, like banishing, imprisoning, etc.
• All diplomatic interactions with other nations.

The senate can block an action if less than 40 senators support it. If less than 60 senators back the action, it can be forced through, but it will increase the amount of tyranny. If the Senate approves an action or not depends on its composition, and what the nation's course is. When an action is passed, it impacts the characters of the nation. Loyalty is lost or gained depending on faction membership, and factions gain and lose senators.
