Groupings of inhabited systems organized themselves into informal sectors from before the Infinite Empire. The Galactic Republic was the first body to attempt a large scale application of standardized sectors. A sector was defined by the Republic as having a maximum of 50 inhabited star systems to keep sectors at a manageable level. By Republic law, in state of emergency, an appointed governor-general coordinated military actions with the Senator of a troubled sector. This law was invoked many times during the Clone Wars by Supreme Chancellor Palpatine.
