The Supreme Chancellor is somebody who is a Sith lord, that goes by the name of "The Senate". "The Senate" is the most powerful in the galaxy, second to him being his apprentice. His master, as you may have heard of in "The Tragedy of Darth Plagueis The Wise", trained him. This man goes by another alias as "Sheev Palpatine", being his name by birth, but not his name in trade.
