A large impressive new mural is currently being painted on the side of a building in downtown Warren, Pennsylvania near the roundabout at the intersection of Pennsylvania Avenue and Market Street highlighting various aspects of Warren's history.
One of the most prominent components of the new mural is an image of the famous Chief Cornplanter of the Iroquois Indians, an important signatory of the 1794 Treaty of Canandaigua between the Iroquois and the United States of America.
Did you know that Friends of Allegheny Wilderness has proposed that a 3,022-acre portion of the Allegheny National Forest along the western shoreline of the Allegheny Reservoir be permanently protected from all forms of development as wilderness under the Wilderness Act of 1964, in part to honor Chief Cormplanter and his legacy?

☀️Day 9 Warren, PA Mural progress. Today we finished Chief Cornplanter, a prominent figure in our county’s history. Here to elaborate is our local historical society:
CHIEF CORNPLANTER (1738—1836)
Cornplanter, also known as Gy-ant-wa-kia or John O’Bail, was Chief of the Seneca Nation and a war Chief of the Six Nations of the Iroquois. After the British lost the Revolutionary War, Chief Cornplanter was instrumental in convincing the Six Nations of the Iroquois, including the Seneca Tribe, to negotiate with the newly formed United States Government. He became a strong diplomatic influence in aiding the government in negotiating settlements and treaties with other Iroquois tribes.
Chief Cornplanter was a dominant force in two such treaties. First, in 1784, Cornplanter traveled to the Six Nations’ villages to encourage ratification of the Fort Stanwix Treaty. The chiefs of the Six Nations, as well as the Delaware and Shawnee tribes, ratified the treaty. The Fort Stanwix Treaty was intended as a peace treaty between the U.S. Government and the Six Nations of the Iroquois.
Chief Cornplanter was granted 600 acres in Forest County near West Hickory, 300 acres in Venango County near Oil City, and 600 acres on the Allegheny River in Warren County, about three miles below the New York State boundary in Pennsylvania. Chief Cornplanter sold the Forest and Venango County tracts and kept the Warren County tract.
In 1794, Chief Cornplanter helped to negotiate the Treaty of Canandaigua, also known as the Pickering Treaty, between the United States Government and the Six Nations of the Iroquois. This treaty provided land and access for the Seneca Tribe, but would later be rescinded by the Government to make way for the Kinzua Dam and Allegheny Reservoir.
