[Tolkien] There are five wizards, right? Gandalf, Saruman, Raddagast... Who are the other two?

The Blue Wizards, Morinehtar and Romestamo, traveled into the East early on. They attempted to stir up rebellion against Sauron's rule and undermine his strongholds in the area. Tolkien went back and forth on how successful they were, but his latest writings suggest they did quite well. Otherwise Sauron's eastern armies would have far outnumbered the free peoples of the West and he would have conquered them long before LotR.
