The Haundenosaunee Confederacy describes the role of the Peacemaker in its origins:

The Haundenosaunee Confederacy has been in place since time immemorial. The Peacemaker was sent by the Creator to spread the Kariwiio or good mind. With the help of Aiionwatha commonly known as Hiawatha, the Peacemaker taught the laws of peace to the Haudenosaunee. Travelling from community to community they both succeeded in persuading the Chiefs of each nation to join in the Great League of Peace and founded the only government with a direct connection to the Creator.
