When they were young and relatively unknown during the Second Great Shinobi World War they fought against Hanzō, and for being able to survive his attacks he gave them the title of Konoha's Sannin in return for letting them live. Now Their names are known in countries all across the world.

The Sannin are widely regarded for their great skill and power, each one has the level of being a Kage in their own right; each has been considered for the position of Hokage at different points in time, with one of them obtaining the title. When Orochimaru defected from Konoha after being denied the position, the Sannin were disbanded, though they continued to be known by the title.
