He later rose to the rank of Supreme Chancellor.
In Empire at WarEdit
Here Palpatine appears as the leader of the Empire. Not only does he wield a lightsaber and Force Lightning and Force Corrupt, but he also grants the the Empire the ability to build anything (be it structures, units, or ships) on the planet he resides on for 25% less than normal. This allows the player to more easily construct a Death Star and other expensive units and equipment.
