The Kekkon clan was founded centuries before the formation of the hidden villages. Like many the Kekkon clan fought against others during the warring states period of time, sometime fighting against the Uchiha and Senju clans. They grew some notoriety for their Kekkei Genkai, and were constantly invited to create an alliance with the Senju Clan and other minor clans. At the end of the Warring states Period and the formation of the hidden villages the Kekkon clan accepted an invitation by Hashirama Senju to join the newly formed Konohagakure.
