History
First settled in 1829 on a site tentatively named "Washington", the town was officially founded in 1830 as the county seat of McDonough County and given the name "Macomb" after Alexander Macomb, a general in the War of 1812. War veterans were given land grants in the Macomb area, which was part of the "Military Tract" set aside by Congress.

Macomb has been visited by several US Presidents over the years. Ulysses S. Grant, Andrew Johnson, Rutherford B.

On two occasions, Abraham Lincoln and Barack Obama addressed large audiences prior to their election as president. Obama was stumping for the U.S. Senate at the time, meaning a president or presidential nominee has not visited Macomb in 109 years and counting.

In 2005, the Rams decided to move summer training to their own facilities in St. Louis,…
