<p>Over ten thousand Britons fought as police in the First Irish War ( 1920-21 ). Most of these British police were ex-soldiers, veterans of the Great War and members of the Royal Irish Constabulary (RfC), called 'Black and Tans' for their mixed uniforms of dark police green and military khaki. Ex-officers joined a separate force, the Auxiliary Division (ADRIC), a special emergency gendarmerie, heavily armed and organized in military-style companies. Pitted against the guerrillas of the Irish Republican Army (IRA), the Black and Tans and Auxiliaries took many 'reprisals', assassinating Irish republicans and burning their homes and shops. As a consequence, their name became a byword for crime and violence, and the specter of 'black-and-tannery' has haunted Ireland ever since.</p> <p>This dissertation uses evidence from both British and Irish archives and from British newspapers to study the British police and their behaviour in the First Irish War. According to legend the Black and Tans and Auxiliaries were ex-convicts and psychopaths, hardened by prison and crazed by war. In fact, most of them were quite ordinary men, whose violent and criminal behaviour was a proud of circumstance, not character. The British government would not believe that the conflict in Ireland was a war, and relied on the police to suppress the rebel 'murder gang.' Unsuited for guerrilla warfare, the RIC was already losing its discipline and committing atrocities before its British reinforcements arrived. British constables lived and worked alongside Irish constables, and followed their example, good or bad. Freed from the sometimes moderate influence of the constabulary's Irish majority, Auxiliaries behaved with even greater license than Black and Tans. The violence of the British and Irish police was overlooked and even encouraged by the British government, which was anxious to keep up the pretence that Irish revolutionaries were merely terrorists and gangsters.</p> / Doctor of Science (PhD)

From 1906 to 1912 the British police contended with the struggles of militant suffragettes and active unionists. In facing the disturbances associated with the suffragette movement and union mobilization, the police confronted the dual problems of maintaining the public order essential to the survival and welfare of the kingdom while at the same time assuring to individuals the liberty necessary for Britain's further progress. This dissertation studies those police activities in detail.
