Theocracy is a form of government in which priests or god men rule in the name of God.
Explanation:
In a Theocracy the ultimate power of the government resides wit the representative of God. It could be a priest or an elected representative by a process religious or democratic.
The person thus elected is seen as the representative of God and wields all the power in the dominion. The government is then run by that person and their chosen government.
This form has been around for ages as theocracies were common in Europe throughout the existence of Catholicism.
The government wasn't powerful enough. They couldn't even tax the people, so the government was too broke to offer any kind of assistance when it's country was in need. (Couldn't afford a military when they needed it, for example -- there were a lot of domestic issues that they couldn't take care of.)
