The state of Indiana officially created Lawrence County in January 1818, but it took a while for things to really get going. There weren't enough buildings in the area that could be used to establish county government. There was no building that could be protected for a court or jail.
All this had to be built, so the first functions of government took place in homes. Even the first elections were often held in homes. In Indiana, the most common number associated with counties is the state's county code, which is a sequential number based on the alphabetical order of the county. The parties were divided into all of Allen, Bartholomew, Hamilton, Henry, Johnson, Marion, Rush and Shelby Counties.
Indiana contains some counties that no longer exist because they were discontinued, renamed, or merged with another county.
