The first European settlement in Michigan was founded by French explorer Antoine de la Mothe Cadillac in 1701. He established the settlement of Fort Pontchartrain du Détroit (later known as Detroit), which became an important trading post and military stronghold for the French and later the British.
Alger County is located in the Upper Peninsula of Michigan. It was originally inhabited by Native American tribes, including the Ojibwa and the Potawatomi. The area began to attract European settlers in the mid-1800s due to its natural resources, such as timber and iron ore.

In 1873, Alger County was officially established, named after Russell A. Alger, who was a governor and senator of Michigan at that time. The county experienced rapid growth during the late 19th and early 20th centuries, primarily due to the iron ore industry. Several mining communities were established, including Munising, which became the county seat.

The iron ore boom brought prosperity to Alger County, with mines and mills employing thousands of workers. However, this period of growth started to decline towards the mid-20th century. The closure of mines and the decline in the demand for iron ore led to economic challenges for the county.

In recent years, Alger County has turned to tourism and outdoor recreation as a major source of economic activity. The county is known for its stunning natural beauty, including Pictured Rocks National Lakeshore, which attracts thousands of visitors each year. The local economy now relies heavily on tourism, as well as forestry and manufacturing. Alger County continues to preserve its rich history while embracing its scenic landscapes to attract visitors and create opportunities for its residents.
