Why do you think the struggle in Kansas was called a mini civil war?

The struggle in Kansas, known as "Bleeding Kansas," was termed a mini civil war because it involved violent confrontations between pro-slavery and anti-slavery factions in the mid-1850s. This conflict arose in the context of the broader national debate over slavery, particularly following the Kansas-Nebraska Act, which allowed settlers to determine the status of slavery in their territories. The intense clashes, political turmoil, and bloodshed mirrored the divisions that would later culminate in the American Civil War, making it a precursor to larger national conflict.
