It’s worth remembering that the Civil War transformed the entire nation, not just the South. From the tribes living in Montana to the slaves in Mississippi to Yankees in Vermont, no one in this nation was the same after 1865. That includes Chicago:
Some impacts, courtesy of Chicago History Museum and the Encyclopedia of Chicago:
• Boosted commerce: “The opening of the Union Stock Yard on Christmas Day, 1865, is symbolic of the Civil War’s impact on Chicago. The war directed the flow of vital food commodities away from Chicago’s most persistent urban rivals, which were too close to the front lines during the first two years of the war and were hurt by stoppages of trade on the Mississippi and Ohio Rivers.”
• Helped banking: “The Civil War also helped spur industrialization by bringing stable banking to Chicago for the first time. The First National Bank of Chicago was founded in July 1863, and by war’s end the city boasted 13 national banks, more than any other city in America.”
• Race riot: “In 1862 the city suffered its first race riot when white teamsters tried to prevent African-Americans from using the omnibus system. The Chicago City Council voted to segregate the public schools.”
• POW camp: Chicago was home to one of the largest Union Army prisoner-of-war camps for Confederate soldiers: Camp Douglas, near 35th Street and Martin Luther King Drive. Of the 10,000-plus Confederate soldiers at the camp, 4,457 died, mostly due to poor sanitary and medical facilities. The Chicago History Museum has several artifacts from the camp, including the bell that rang out to signify the end of the Civil War.
• Death toll: There were 22,436 soldiers from Cook County, and most came from Chicago. Almost 4,000 soldiers from the city died, and there are memorials in Grant Park, Lincoln Park and some city cemeteries.
“Thousands of Confederate soldiers are buried in Lincoln Park [formerly the city cemetery] and in Oak Wood Cemetery, which has a significant monument memorializing the rebel soldiers who perished at Camp Douglas,” Lewis said.
Wait, there’s a Confederate monument in Chicago?
Anyway, this is a nice overview of the basics.
