Government

Government is one of the most fundamental elements of your interstellar domain. Choosing a form of government is a strategic, long-term consideration, introduced in Master of Orion II.

Master of Orion II
There are four basic forms of government, each of which has an advanced government form available. You cannot change your government, except for upgrading to a superior form.


 * Feudalism → Confederation
 * Dictatorship → Imperium
 * Democracy → Federation
 * Unification → Galactic Unification

Master of Orion III
There are multiple government forms available. You can switch between them in the game, though it will cause significant unrest throughout your empire.

 * Despotism
 * Monarchy
 * Oligarchy
 * Constitutional monarchy
 * Corporate
 * Democracy
