===Industrialization and immigration===
[[Inland Steel Company]] established a plant in East Chicago in 1903 and [[U.S. Steel]] founded one in Gary in 1906; with industrial jobs the demand for labor associated with industrial jobs, the county's population exploded. Immigrants poured into the area from all over Central and Eastern Europe (there was also a smaller Mexican immigrant community). In addition, both black and white migrants came from many regions of the United States, particularly [[Appalachia]] and the South. Mostly rural blacks went north in the [[Great Migration (African American)|Great Migration]], seeking both industrial jobs and escape from [[Jim Crow]] violence and disenfranchisement in the South.

By 1930, Lake County's population surpassed 260,000, with first- and second-generation Americans constituting a majority of the population. The second wave of the [[Ku Klux Klan]] gained a large following here in the 1920s, as it did for a time in the rest of Indiana. The KKK organized against the numerous European immigrants, who were mostly Catholic. While the steel industry reigned supreme, other industries also found the county to be an ideal location for cheap land and well-developed transportation networks, such as automobiles, oil, chemicals, consumer goods, food processing, and construction supply companies.<ref name="auto">{{cite web |title=Lake County, IN |url=http://www.encyclopedia.chicagohistory.org/pages/707.html |website=Encyclopedia of Chicago |publisher=Chicago History Museum |access-date=October 3, 2018}}</ref>

The [[Great Depression]] was devastating to Lake County, as it was to other areas with economies based on [[heavy industry]]. The Depression, combined with industrial strife, changing demographics, and unionization, caused a realignment of politics in Lake County. It became a stronghold of the [[Democratic Party (United States)|Democratic Party]]; Lake County has supported the Democratic nominee for president in every election since 1932 (exceptions occurred in 1956 and 1972). [[Indiana's 1st congressional district]] has elected Democratic candidates in every election since 1930.

[[World War II]] restored prosperity, as industry revived to support the war effort. Good economic times continued into the 1970s. During this period, unions helped industrial workers gain middle-class wages. In addition to attracting refugees and immigrants from Europe, [[black Americans]] and Mexicans migrated here in the postwar period in even higher numbers than in the 1910-1930 period. As minority populations exploded in such industrial cities as East Chicago and Gary, racial tensions surfaced again. Following construction of state and federal highways, development of cheaper land provided newer housing to middle-class people who could afford it. Both [[white flight|whites]] and established black families moved out of the aging industrial cities.<ref name="auto"/>
