On September 17, 1778, the United States and the Lenape signed the first formal treaty between the new republic and a Native American group at Fort Pitt.
The Treaty of Fort Pitt, also known as the Treaty With the Delawares, the Delaware Treaty, or the Fourth Treaty of Pittsburgh, was signed on September 17, 1778. It was the first formal treaty between the new United States of America and any Native American groups, in this case the Lenape, called the Delaware by white settlers. Although informal agreements had occurred during the Revolutionary War, this was the first to result in a formal document, signed at Fort Pitt, Pennsylvania, now the site of Downtown Pittsburgh.
