Michigan ( (listen)) is a state in the Great Lakes region of the upper Midwestern United States. Its name derives from a gallicized variant of the original Ojibwe word ᒥᓯᑲᒥ (mishigami), meaning 'large water' or 'large lake'. With a population of nearly 10.1 million and a total area of nearly 97,000 sq mi (250,000 km2), Michigan is the 10th-largest state by population, the 11th-largest by area, and the largest by area east of the Mississippi River. Its capital is Lansing, and its largest city is Detroit. Metro Detroit is among the nation's most populous and largest metropolitan economies.

Michigan is the only state to consist of two peninsulas. The Lower Peninsula is shaped like a mitten. The Upper Peninsula (often called "the U.P.") is separated from the Lower Peninsula by the Straits of Mackinac, a five-mile (8 km) channel that joins Lake Huron to Lake Michigan. The Mackinac Bridge connects the peninsulas. Michigan has the longest freshwater coastline of any political subdivision in the world, being bordered by four of the five Great Lakes, plus Lake St. Clair. It also has 64,980 inland lakes and ponds. Michigan has the second-most water of any state, behind only Alaska.The area was first occupied by a succession of Native American tribes over thousands of years. Inhabited by natives, Métis, and French explorers in the 17th century, it was claimed as part of the New France colony. After France's defeat in the French and Indian War in 1762, the region came under British rule. Britain ceded the territory to the newly independent United States after Britain's defeat in the American Revolutionary War. The area was part of the larger Northwest Territory until 1800, when western Michigan became part of the Indiana Territory. Michigan Territory was formed in 1805, but some of the northern border with Canada was not agreed upon until after the War of 1812. Michigan was admitted into the Union in 1837 as the 26th state, a free one. It soon became an important center of industry and trade in the Great Lakes region and a popular émigré destination in the late 19th and early 20th centuries; immigration from many European countries to Michigan was also the busiest at that time, especially for those who emigrated from Finland, Macedonia and the Netherlands.Although Michigan developed a diverse economy, it is widely known as the center of the U.S. automotive industry, which developed as a major economic force in the early 20th century. It is home to the country's three major automobile companies (whose headquarters are all in Metro Detroit). While sparsely populated, the Upper Peninsula is important for tourism due to its abundance of natural resources, while the Lower Peninsula is a center of manufacturing, forestry, agriculture, services, and high-tech industry.
