The beginnings of Detroit are inaccurately pinned to the arrival of Cadillac on these shores in 1701, but there were various Native American tribes in the area for centuries before that. Thousands of years ago, people came over on a land bridge from Siberia to Alaska. The earliest indigenous people around Detroit were suspected to have come here for sturgeon in the Detroit river. They even left something that is still around to this day: a burial mound at Fort Wayne, on Detroit's southwest side.
