Penn achieved peaceful relations with the Indians--Susquehannocks, Shawnees, and
Leni-Lenape. Indians respected his courage, because he ventured among them
without guards or personal weapons. He was a superior sprinter who could out-run
Indian braves, and this helped win him respect. He took the trouble to learn
Indian dialects, so he could conduct negotiations without interpreters. From the
very beginning, he acquired Indian land through peaceful, voluntary exchange.
Reportedly, Penn concluded a "Great Treaty" with the Indians at Shackamaxon,
near what is now the Kensington district of Philadelphia. Voltaire hailed this
as "the only treaty between those people [Indians and Christians] that was not
ratified by an oath, and that was never infringed." His peaceful policies
prevailed for about 70 years, which has to be some kind of record in American
history.
