The 1682 Treaty of Friendship was forged in Shackamaxon (see Part I) with the assumption that the rivers and creeks of Philadelphia would always run – this would of course not be the case.^xi In 1737, the Lenape were tricked by William Penn’s sons into relocating to nearby river valleys and were eventually forced by the federal government to relocate to Oklahoma.^xii Two federally recognized tribes of Lenape remain in Oklahoma today, the Delaware Nation (aka Western Delaware) and the Delaware Tribe of Indians (aka Eastern Delaware) with populations of 1,422 and 10,529 respectively. The Lenape Nation of Pennsylvania, a community of Native Americans in the Lehigh Valley is not federally recognized but is actively reviving their language and culture.^xiii The exhibit, “Fulfilling the Prophecy: the Past and Present of the Lenape in Pennsylvania,” on display through 2011 at the Penn Museum presents the story of the Lenape who managed to stay behind during the forced migrations.^xiv The Lenape Nation of Pennsylvania is currently seeking state recognition and a new Treaty of Friendship is collecting signatures.
