Michigan's earliest history is defined by indigenous peoples, most notably the Anishinaabe (the Ojibwe, Odawa, and Potawatomi, known as the Council of Three Fires). French explorers and missionaries, including Étienne Brûlé and Jacques Marquette, arrived in the 17th century, establishing fur trading posts and settlements like Sault Ste. Marie (1668) and Detroit (1701). Following the French and Indian War, control passed to the British in 1763, and eventually to the United States after the American Revolutionary War.
Michigan officially became an organized U.S. territory in 1805. Its path to statehood was delayed by the Toledo War—a near-bloodless boundary dispute with Ohio over the Toledo Strip. As a compromise, Michigan ceded Toledo to Ohio and in exchange received the entire Upper Peninsula. Michigan was admitted to the Union as the 26th free state on January 26, 1837.
In the late 19th and early 20th centuries, Michigan transformed the global economy. The state became the center of the global automotive industry, led by pioneers like Henry Ford, William C. Durant, and Ransom E. Olds. The massive influx of manufacturing jobs drew waves of immigrants from Europe and African Americans from the South during the Great Migration. During World War II, Michigan's massive industrial capacity earned it the title "Arsenal of Democracy."
The latter half of the 20th century saw periods of racial tension, labor rights milestones established by the United Auto Workers (UAW), and the musical revolution of Motown. While the late 20th century brought economic challenges and deindustrialization (the "Rust Belt" era), the 21st century has seen a robust revitalization of Detroit and a diversification of the state's economy into technology, healthcare, and green energy.
