Michigan ( MISH-ig-ən) is a peninsular state in the Great Lakes and Upper Midwest regions of the United States. It shares water and land boundaries with Minnesota to the northwest, Wisconsin to the west, Indiana and Illinois to the southwest, Ohio to the southeast, and the Canadian province of Ontario to the east, northeast and north. With a population of 10.13 million and an area of 96,716 sq mi (250,490 km2), Michigan is the tenth-most populous state and the 11th-largest state by area. The state capital is Lansing, while its most populous city is Detroit. Other important metropolitan centers include Grand Rapids, Flint, Ann Arbor, Kalamazoo, the Tri-Cities, and Muskegon.
Michigan consists of two peninsulas: the more populated Lower Peninsula and the heavily forested Upper Peninsula, separated by the Straits of Mackinac. Bordering four of the five Great Lakes and Lake St. Clair, Michigan has the longest freshwater coastline of any U.S. political subdivision, measuring 3,288 miles. The state ranks second behind Alaska in water coverage by square miles and first in percentage, with approximately 42%, and it also contains 64,980 inland lakes and ponds. It is the largest state by total area east of the Mississippi River.
The Great Lakes region has largely been inhabited for thousands of years by Indigenous peoples such as the Ojibwe, Odawa, Potawatomi, and Wendat. In the 17th century, French explorers claimed the area for New France, which came under British control after the French and Indian War in 1762. Following the Treaty of Paris (1783), the area was part of the larger Northwest Territory of the U.S.; the Michigan Territory was organized in 1805. Michigan was admitted as the 26th state on January 26, 1837, entering as a free state and quickly developing into an industrial and trade hub that attracted European immigrants, particularly from Finland, Macedonia, and the Netherlands. Migration from Appalachia and the Great Migration of Black Southerners in the 20th century further shaped the state, especially in Metro Detroit.
Michigan has a diversified economy with a gross state product of $771.1 billion as of Q2 2026, ranking 14th among the 50 states. Although the state has developed a diverse economy, in the early 20th century it became widely known as the center of the U.S. automotive industry, which developed as a major national economic force. It is home to the country's three major automobile companies (whose headquarters are all in Metro Detroit). Once exploited for logging and mining, today the sparsely populated Upper Peninsula is important for tourism because of its abundance of natural resources. The Lower Peninsula is a center of manufacturing, forestry, agriculture, services, and high-tech industry.
Some people contend that the region's name is derived from the Ojibwe word ᒥᓯᑲᒥ (mishigami), meaning "large water" or "large lake". Others say that it comes from the Mishiiken Tribe of Mackinac Island, also called Michinemackinawgo by Ottawa historian Andrew Blackbird, whose surrounding lands were referred to as Mishiiken-imakinakom, later shortened to Michilimackinac.
When the first European explorers arrived, the most populous tribes in what is now Michigan were the Algonquian peoples, which include the Anishinaabe groups of Ojibwe, Odaawaa/Odawa (Ottawa), and the Boodewaadamii/Bodéwadmi (Potawatomi). The three nations coexisted peacefully as part of a loose confederation called the Council of Three Fires. The Ojibwe, whose numbers are estimated to have been at least 35,000, were the largest.
The Ojibwe (also known as Chippewa in the U.S.), an Anishinaabe tribe, were established in Michigan's Upper Peninsula and northern and central Michigan. Bands also inhabited Ontario and southern Manitoba, Canada; and northern Wisconsin, and northern and north-central Minnesota. Smaller groups of Algonquian Indians like the Noquet in the Upper Peninsula were present for thousands of years but subsequently absorbed by neighboring tribes before and during European contact. The Odawa lived primarily south of the Straits of Mackinac in northern, western, and southern Michigan, but also in southern Ontario, northern Ohio, and eastern Wisconsin. The Potawatomi were in southern and western Michigan, in addition to northern and central Indiana, northern Illinois, southern Wisconsin, and southern Ontario. Other Algonquian tribes in Michigan, in the south and east, were the Mascouten, the Menominee, the Miami, the Sauk (or Sac), and the Meskwaki (Fox). The Wendat were an Iroquoian-speaking people in this area; they were historically known as the Huron by the French, and were the historical adversaries of the Haudenosaunee (Iroquois) Confederation.
French voyageurs and coureurs des bois explored and settled in Michigan in the 17th century. The first Europeans to reach what became Michigan were those of Étienne Brûlé's expedition in 1622. The first permanent European settlement was founded in 1668 on the site where Père Jacques Marquette established Sault Ste. Marie, Michigan, as a base for Catholic missions. Missionaries in 1671–75 founded outlying stations at Saint Ignace and Marquette. Jesuit missionaries were well received by the area's Indian populations, with few difficulties or hostilities. In 1679, Robert Cavelier, Sieur de la Salle built Fort Miami at present-day St. Joseph. In 1691, the French established a trading post and Fort St. Joseph along the St. Joseph River at the present-day city of Niles.
In 1701, French explorer and army officer Antoine de la Mothe Cadillac founded Fort Pontchartrain du Détroit or "Fort Pontchartrain on-the-Strait" on the strait, known as the Detroit River, between lakes St. Clair and Erie. Cadillac had convinced Louis XIV's chief minister, Louis Phélypeaux, Comte de Pontchartrain, that a permanent community there would strengthen French control over the upper Great Lakes and discourage British aspirations.
The hundred soldiers and workers who accompanied Cadillac built a fort enclosing one arpent (about 0.85 acres (3,400 m2), the equivalent of just under 200 feet (61 m) per side) and named it Fort Pontchartrain. Cadillac's wife, Marie Thérèse Guyon, soon moved to Detroit, becoming one of the first European women to settle in what was considered the wilderness of Michigan. The town quickly became a major fur-trading and shipping post. The Église de Saint-Anne (Catholic Church of Saint Anne) was founded the same year. While the original building does not survive, the congregation remains active. Cadillac later departed to serve as the French governor of Louisiana from 1710 to 1716. French attempts to consolidate the fur trade led to the Fox Wars, in which the Meskwaki (Fox) and their allies fought the French and their Native allies.
At the same time, the French strengthened Fort Michilimackinac at the Straits of Mackinac to better control their lucrative fur-trading empire. By the mid-18th century, the French also occupied forts at present-day Niles and Sault Ste. Marie, though most of the rest of the region remained unsettled by Europeans. France offered free land to attract families to Detroit, which grew to 800 people in 1765. It was the largest city between Montreal and New Orleans. French settlers also established small farms south of the Detroit River opposite the fort, near a Jesuit mission and Wyandot village.
From 1660 until the end of French rule, Michigan was part of the Royal Province of New France. In 1760, Montreal fell to the British forces, ending the French and Indian War (1754–1763), the North American front of the Seven Years' War in Europe. Under the 1763 Treaty of Paris, Michigan and the rest of New France east of the Mississippi River were ceded by defeated France to Great Britain. After the Quebec Act was passed in 1774, Michigan became part of the British Province of Quebec. By 1778, Detroit's population reached 2,144 and it was the third-largest city in Quebec province.
During the American Revolutionary War, Detroit was an important British supply center. Most of the inhabitants were French-Canadians or American Indians, many of whom had been allied with the French because of long trading ties. Because of imprecise cartography and unclear language defining the boundaries in the 1783 Treaty of Paris, the British retained control of Detroit and Michigan after the American Revolution. When Quebec split into Lower and Upper Canada in 1791, Michigan was part of Kent County, Upper Canada. It held its first democratic elections in August 1792 to send delegates to the new provincial parliament at Newark (now Niagara-on-the-Lake).
