It was also the home of Kansas Governor and U.S. Senator Frank Carlson. As of the 2010 census, the city population was 5,395.
Concordia holds the distinction of being elected the county seat before the town was created. The founder of the town, James M. Hagaman had created a complete layout of the town on paper including streets, blocks, courthouse, and parks. The name "Concordia" was chosen because a member of the early group of promoters ("Cap" Snyder) had once lived in Concordia, Missouri.
December 1869 was the first election for the county seat with Concordia, Clyde and the now defunct town Sibley. Without a clear majority, a second election was held between Concordia and Sibley on January 4, 1870. Concordia was declared the winner over Sibley 165 votes to 129.
