Fulbright is the longest serving chairman in the history of the Senate Foreign Relations Committee. A Southern Democrat and a staunch multilateralist who supported the creation of the United Nations, he was also a segregationist who signed the Southern Manifesto.

His efforts to establish an international exchange program eventually resulted in the creation of a fellowship program which bears his name, the Fulbright Program.
