The Castaic Range War, also known as the Jenkins-Chormicle Affair, was a range war that happened in Castaic, California from 1890 to 1916, between ranchers and farmers William Willoby Jenkins and William C. Chormicle, who both staked claims on a piece of land in the territory. The feud started when Jenkins fell into a dispute with Chormicle when the latter purchased 1,600 acres of the same land he had settled in years ago. When the problem couldn't be settled on court, violence then erupted between the two which lasted for over two decades, in which dozens of men from both sides were killed. William Chormicle died of old age in 1919. The Castaic affair was one of the largest range war in American history, as well as becoming one of the bloodiest event in the state.
