It is part of the Chicago metropolitan area and is the second-most populous county in the state, anchored by major cities like Hammond, Gary, and East Chicago.

History

The region was originally inhabited by the Potawatomi people before European exploration and settlement. Lake County was created by an act of the Indiana General Assembly on February 15, 1837, from portions of Porter County and Newton County. The late 19th and early 20th centuries saw explosive growth due to the expansion of the steel industry, led by companies like the Illinois Steel Company and the founding of the city of Gary by the United States Steel Corporation in 1906. The county was a major destination during the Great Migration, profoundly shaping its demographic and cultural landscape, and was the site of significant labor history, including the Steel Strike of 1919.
