Lake County was created on February 15, 1837 and was formed from Porter and Newton Counties. The County was named for its location on Lake Michigan.
The County Seat is Crown Point. Crown Point wasn't always the County Seat. Prior to establishing the County Seat, court was conducted in the home of Milo Robinson, as nearly all the lands within the limits of Lake County were still the property of the government. Liverpool was selected the first County Seat, however, the site was not satisfactory to a majority of the citizens. The County Seat was moved back to the location of Milo Robinson's home and was originally to be called "Lake County Courthouse," however, the name being too cumbersome, it was suggest that the county agent, George Earle, and the two proprietors, Judge Clark and Solon Robinson, select a new name. They settled on Crown Point. First settled in 1835, by Solon Robinson, Esq., by 1849 Crown Point contained three stores, one hotel, Presbyterian and Methodist churches, a good High School kept by the Rev. Wm. Townley, and about thirty-five dwelling houses.
