History Beebe's Corners, the original settlement in what would become the city of Warren, was founded in 1830 at the corner of Mound Road and Chicago Road; its first resident was Charles Groesbeck. Beebe's Corners was a carriage stop between Detroit and Utica, and included a distillery, mill, tavern, and trading post. It was not until 1837 that the now-defunct Warren Township was organized around the settlement, first under the name Hickory, then renamed Aba in April 1838, and finally renamed Warren shortly thereafter. It was named for War of 1812 veteran, and frontier cleric, Rev. Abel Warren. However, when it was originally organized the township was named for Rev. Warren who was a Methodist Episcopal preacher who left his native New York in 1824 for Shelby Township. He went throughout the present-day Macomb, Lapeer, Oakland, and St. Clair Counties, baptizing, marrying, and burying pioneers of the area, as well as establishing congregations and preaching extensively. He was the first licensed preacher in the State of Michigan. Another version of the source of the city's name claims it was "named for General Joseph Warren, who fell at the Battle of Bunker Hill. The settlement was formally incorporated as the Village of Warren from Warren Township on April 28, 1893 out of one square mile bound by 14 Mile Road and 13 Mile Road to the north and south, and in half-a-mile east and west of Mound Road. The small village grew slowly, and had a population of 582 in 1940 and 727 in 1950, while the larger surrounding township grew at a much quicker pace. Much of this growth was due to the construction of the Chrysler's Truck Assembly plant in 1938, the Detroit Arsenal Tank Plant
