The Harlan County War, or Bloody Harlan, was a series of coal mining-related skirmishes, executions, bombings, and strikes (both attempted and realized) that took place in Harlan County, Kentucky, during the 1930s.
 The incidents involved coal miners and union organizers on one side and coal firms and law enforcement officials on the other.
 The question at hand: the rights of Harlan County coal miners to organize their workplaces and better their wages and working conditions.
 It was a nearly decade-long conflict, lasting from 1931 to 1939.
 Before its conclusion, two acclaimed folk singers would emerge, state and federal troops would occupy the county more than half a dozen times, an indeterminate number of miners, deputies, and bosses would be killed, union membership would oscillate wildly, and workers in the nation's most anti-labor coal county would ultimately be represented by a union.

The Battle of Evarts is the name given to a mining strike and ensuing violence that occurred in Harlan County, Kentucky, in 1931.
 In February 1931 The Harlan County Coal Co. cut wages for its employees.
 The United Mine Workers union responded by holding a rally in Pineville, drawing over 2,000 attendees.
 This and other wage cuts and firings led to a strike, and on May 5 Sheriff Jim Daniels (who was reportedly on the payroll of the Black Mountain Coal Co.) and "three carloads of deputies armed with machine guns, sawed off shotguns and rifles drove into Evarts" to confront the striking miners.
 It is unclear who fired first, but after the battle Jim Daniels, two of his deputies and one miner had died.
 Eventually Gov. Flem D. Sampson called in the National Guard to stop the strike.
 It ended in June after several deaths and arrests.
