The Federal Empire is led by God Empress Athena (The God of War) After she grows board and decides to lead the human Mars colony. The Federal Empire still has a functioning "Democracy" in a way. People are still elected by votes to the House and Senate, but all they do is write and vote on articles and vote on ideas to present to the Empress (though she is not required to listen) and creates laws and Govt functions by her order.
The Govt prioritizes Law and Order and Defense over individual rights. The Empress's power is unchallengeable, as she rules happily.
