About St. Tammany Day

St. Tammany Day was established in 2003 when it was ratified by the U.S. Congress, as a day of recognition in honor of Tamanend, the “affable” (c. 1628–c. 1698), who was a chief of one of the clans that made up the Lenni-Lenape nation in the Delaware Valley.

Tamanend  or "Tammany" is best known as a strong proponent of peace, who played a prominent role in peaceful relations among the Native American tribes and the English settlers, led by William Penn, established Pennsylvania.

Tamanend reputedly took part in a meeting between the leaders of the Lenni-Lenape nation, and the leaders of the Pennsylvania colony held under a large elm tree at Shakamaxon in the early 1680s. There, Tamanend is reported to have announced that the Lenni-Lenape and the English colonists would “live in peace as long as the waters run in the rivers and creeks and as long as the stars and moon endure.” These words have been memorialized on the statue of Tamanend that stands in Philadelphia today.
