Monarch

Monarch is a vampire who has rule over their state.

Their jobs consist of hiring new sheriff's, carrying out punishments against vampires. They're most notably considered to be "Queen" or "King." Usually vampires who are older, get the position. In some cases it's not true. With Louisiana, Bill Compton became King where Eric Northman was the oldest vampire.

Each state has a Vampire Queen or King. They are given the position by the Authority. When Sophie Anne Leclerq was destroyed, Nan Flanagan give Bill Compton the title of "King of Louisiana," on the spot.

Depending on the severity of the crime, the Vampire Queen or King, has the right to destroy a Vampire in their king/queen-dom. (Case: When a Vampire was on YouTube feeding on a human, even though the human was willing, Bill Compton had to put him to death.)
