Significance:

  • Horace Greeley, publisher of the New York Tribune, reportedly coined the term “Bleeding Kansas” to describe the escalating violence in the Kansas Territory during the 1850s.
  • Pro-slavery partisans who operated in Bleeding Kansas were known as Border Ruffians.
  • Anti-slavery partisans who operated in Bleeding Kansas were known as Free-Staters and Jayhawkers.
  • The Battle of Osawatomie was the largest armed conflict to take place in Bleeding Kansas.
  • Recent historical research documents 157 homicides in Kansas between 1854 and 1861. Of those, only fifty-six can be directly attributed to political differences regarding slavery – roughly eight deaths per year. By comparison during the 1850s, Los Angeles County, California experienced homicide rates ranging from 110 to 414 deaths per 100,000 people.
  • Much of the hysteria engendered by the turbulence in Bleeding Kansas was a product of sensationalized reports published by Northern and Southern newspapers intended to foment the passions of pro and anti-slavery partisans.
  • The politicized accounts of violence that occurred in Bleeding Kansas intensified the sectional polarization that eventually spawned the Civil War.
