On June 23, 1683, William Penn and Delaware Chief Tamenend (Lenni Lenape tribe) signed a peace treaty in Shackamoxon, Pennsylvania. Tamenend was also called Tammany. He was renowned for his honor and the Tammany societies were thus named after him. In exchange for a long list of supplies, William Penn purchased two plots of land on and between the Pennypack and Neshaminy Rivers from the Chief. The area of land they where sharing was given to Penn by King Charles II.
