The University of Michigan, Ann Arbor (U of M, U-M, UM or simply Michigan) is a coeducational public research university in the state of Michigan.
The university was founded in 1817 in Detroit, about 20 years before the territory of Michigan officially became a state, and moved to Ann Arbor in 1837. Today, it is the state's oldest university and the flagship campus; there are two satellite campuses — the University of Michigan-Flint and the University of Michigan-Dearborn.
The university is internationally renowned for its academics. In its last published survey in 1995, the National Research Council ranked UM third in the United States in a study that aggregated evaluations of 41 graduate disciplines and is considered as one of the original eight Public Ivys. The university also has one of the largest research expenditures of any American university and one of the largest number of living alumni, at 420,000. UM owns one of the most well-regarded academic medical centers in the United States, the University of Michigan Health System. The university is also recognized for its history of student activism and its athletic teams, notably in football, men's basketball, and ice hockey.
