The Hidden leaf village was founded after the great ninja war by the Uchiha and Senju clans. These clans were the two strongest of their time, and when joined together the Hidden leaf village grew quickly, raising in power to become the strongest nation. Over the years that power has dwindled, the Hidden leaf acts as the peace keepers, only acting against those villages that appear, "evil" and cause problems. They are almost always willing to give another chance and fight for what is right. The Hidden leafs true power lies in their clans and strong hearts, they have hidden skills to fight with, and at the same time have the hearts to defend their friends and family.
