History[edit]

Macon County was formed on January 19, 1829 out of Shelby County. It was named for Nathaniel Macon, who served as a Colonel in the Revolutionary War.[3] Macon later served as senator from North Carolina until his resignation in 1828. In 1830, future President Abraham Lincoln and his family moved to Macon County.

Geography[edit]

According to the U.S. Census Bureau, the county has a total area of 586 square miles (1,520 km2), of which 581 square miles (1,500 km2) is land and 5.2 square miles (13 km2) (0.9%) is water.[4]

Macon County is primarily flat, as is most of the state and all of the surrounding counties, as a result of geological activity during the Pleistocene epoch. During the Illinoian Stage of the Pleistocene, the Laurentide ice sheet covered roughly 85 percent of Illinois, including all of present-day Macon County. The subsequent thaw of the region and retreat of the ice sheet left central Illinois with the characteristic flat topography which it is known for today.[5]

Because of its location, Macon County is often referred to as "The Heart of Illinois."[6]
