History
thumb|left|Aitkin County Historical Society Depot MuseumBefore the establishment of City of Aitkin, there was a transient community of Lexington at the mouth of the Ripple River, where it meets the Mississippi River. Maps from the 1860s erroneously depict the village of Ojibway at the mouth of the Ripple River.
Due to the importance of regional trade at Lexington, the Northern Pacific Railroad was planned to pass near there. Aitkin was founded in 1870 when the Northern Pacific Railroad was extended to that point, replacing and annexing Lexington. The city and county were named for William Alexander Aitken, a partner of the American Fur Company and chief factor of the company's regional operations in the early 19th century.
The development of industries attracted people to the town. In the late 19th and early 20th century, a massive wave of immigrants, mostly from present-day Ireland, Germany, Scotland, and Scandinavian countries, moved to the area to work in the logging and riverboat industries. They could work before they had learned much English.
After the Great Depression and World War II, the logging industry declined. The area developed as a farming community, based on production of cattle and poultry, which continued until the early 1980s. A creamery and a turkey plant were important to the town's economy. With the decline of small family farms in agriculture, there are many abandoned farms in the county.
By the 1990s, Aitkin had changed again, developing as a community for retirement and tourism, especially with its lake areas. The tourism and service industries are central today. Health care, education, human services, and nonprofit organizations are some of the major contributors to Aitkin's economy, along with the hospitality industry.
Aitkin has been affected by occasional flooding of the Mississippi River. A 1950 flood reached past and another in 2012 nearly . The 2012 flood was one of the first to overflow into the lake areas, flooding the cabins, as it was caused by heavy rainfall instead of melting snow. In 2023, downtown Aitkin flooded due to record snowfall.
Five properties in Aitkin are listed on the National Register of Historic Places: the 1901 Patrick Casey House, the 1902 Potter/Casey Company Building, the 1911 Aitkin Carnegie Library, the 1916 Northern Pacific Depot, and the Aitkin County Courthouse and Jail (built in 1920 and 1915, respectively).
