What roles does government have in empires?

Governments in empires typically serve to maintain order, enforce laws, and implement policies that promote the interests of the central authority. They manage taxation and resource allocation to support infrastructure and military efforts. Additionally, governments facilitate governance across diverse cultures and regions, often through a combination of direct control and local autonomy. Lastly, they play a crucial role in diplomacy and external relations, helping to expand and sustain the empire's influence.
