Formed on February 4, 1869, Grant County was named in honor of U.S. President-elect Ulysses S.

Robert W. Glover, a Missionary Baptist pastor who served in both houses of the Arkansas General Assembly (1905-1912) from Sheridan, introduced in 1909 the resolution calling for the establishment of four state agricultural colleges.

[5] His brother David Delano Glover was a state representative in the 1907 session and a member of the United States House of Representatives from 1929 to 1935, having been unseated in 1934 by Grant County native John Little McClellan who at the time was practicing law in Camden.

[6] Grant County is considered part of the Arkansas Timberlands geographical area.

Each township includes unincorporated areas; some may have incorporated cities or towns within part of their boundaries.

However, the United States census does list Arkansas population based on townships (sometimes referred to as "county subdivisions" or "minor civil divisions").

Each town or city is within one or more townships in an Arkansas county based on census maps and publications.

[18][19] Grant County is home to Jenkins' Ferry Battleground State Park.
