Enoch Brown School Massacre Of 1764
School massacres didn't start with Columbine. The first recorded mass murder in a school in U.S. history happened a dozen years before the United States was even established, when four Native Americans retaliated against the white settlers who had occupied their land.
The Pontiac Wars
When white settlers moved into the Great Lakes region in the 1700s, they brought upheaval to the Native American people who had made their homes in the area for hundreds of years. In retaliation for the violence brought upon his people, Chief Pontiac of the Ottawa tribe launched an attack on British troops in what is now Detroit on May 7, 1763, leading to a series of hostilities known as the Pontiac Wars that spread into Pennsylvania and upstate New York. Displeased with the chaos, Governor John Penn of Pennsylvania offered a bounty in exchange for the scalps of Native Americans, and in the months that followed, bands of settlers murdered and scalped every Native American they could find.
