Jackson used the spoils system a lot when he was president. He rewarded his supporters and promised future jobs if local and state politicians joined his team. He believed in the theory of rotation in office , where people would only remain in a position for a short time.  He believed that this would keep the civil service from becoming corrupt . Other leaders of the Democratic Party wanted to give civil service jobs to friends and loyal party members. In total, Jackson dismissed less than twenty percent (20%) of the original civil service.
