We know the American Indians first lived in Minneapolis around Lake Calhoun and St. Anthony Falls waterfall. They are called the Dakota or Ojibwe. They thought St. Anthony Falls was a spiritual place. Dakota hunted, fished, and planted food. The United States wanted the land in 1800 and bought it with the Louisiana Purchase. The army built Fort Snelling. Soon, people from the East Coast or "Yankees" came to Minneapolis. They used the waterfall for their flour mills. They named the new city Minneapolis. It comes from the Dakota (American Indian) words for "waterfall" or "Minne ha-ha" and the Greek word for "city" or "polis." Thus Minneapolis means "City of Waters." A nearby city called St. Anthony then joined with Minneapolis. The first mayor was Dorilus Morrison.
