Illinois County

Marion County, Illinois

Salem's William Jennings Bryan birthplace and Illinois's oil heritage - from Salem's William Jennings Bryan Birthplace (the "Great Commoner" - three-time Democratic presidential nominee, Populist movement leader, Secretary of State under Wilson, and prosecution attorney in the Scopes Monkey Trial - was born in Salem on March 19, 1860) to Marion County's significant petroleum production (the Illinois Basin oil fields have produced oil in Marion County since the 1930s, making it one of Illinois's most historically significant oil-producing counties) and the 1947 Centralia Mine Disaster's devastating legacy.
