who wrote bleeding Kansas

Bleeding Kansas was not written by a single author, as it refers to the violent political confrontation in the United States over the issue of slavery in the mid-1850s. However, the events of Bleeding Kansas were extensively covered in newspapers and documented by various historians and journalists of the time. Some notable works on the subject include "Bleeding Kansas: Contested Liberty in the Civil War Era" by Nicole Etcheson and "Bleeding Kansas: From the Kansas-Nebraska Act to Harpers Ferry" by Sara Paretsky.
