Timeline of Michigan history

Natural history

• 13000 BC to 12000 BC The most recent of four major glaciers started to recede, leaving a tundra-like environment. The melting ice formed the Great Lakes, the Upper Peninsula and Lower Peninsula.
• 12800 BC Mastodons and other ice age mammals started to appear in the fossil record.
• 11000 BC to 9000 BC Archeological evidence of Paleo-Indians appeared, in the form of sharpened stone tool points known as fluted biface.

• 1621 or 1622 Étienne Brûlé and his companion Roosevelt paddled up the St. Mary's River and entered Lake Superior.
• 1634 Jean Nicolet, guided by the Wyandot, passed through the Straits of Mackinac and followed the southern shoreline of the Upper Peninsula, en route to find the Ho-Chunk and the imagined passage to the Pacific.
• 1641 Jesuit priests Isaac Jogues and Charles Raymbault followed the same route as Brûlé, finding many Ojibwa at the St. Mary's River rapids and naming it Sault Ste. Marie.
• 1653 The Iroquois Wars virtually emptied the lower peninsula of Native Americans and cut off the Ottawa River route and the St. Lawrence River route into Michigan.

• 1669 Jean Talon sent Adrien Jolliet and Jean Peré on a mission to investigate the Allouez copper reports. Peré appears to have abandoned the mission in favor of fur trading. An Iroquois warrior guided Jolliet's return trip along the eastern shoreline of the Lower Peninsula and down the St. Clair and Detroit Rivers. That may have been the first visit of a European to the Lower Peninsula.
• 1671 June 14 – In "The Pageant of the Sault" at Sault Ste. Marie, Ontario, four Jesuit priests led by Father Claude-Jean Allouez, representing the Roman Catholic Church, and Simon Francois Daumont St. Lusson held aloft a sword and a symbolic tuft of sod, declaring to the Native Americans that all of the Great Lakes country was henceforth a possession of King Louis XIV of France.

• 1715 Fort de Buade was abandoned and Fort Michilimackinac was constructed in what is now Mackinaw City, Michigan.
• 1720 to 1744 was a period of peace, fur trading and little expansion in the part of New France that would become Michigan.
