What happened March 1920 AD

The British increased the use of force; reluctant to deploy the regular British Army into the country in greater numbers, they set up two paramilitary police units to aid the RIC. The Black and Tans were seven thousand strong, mainly ex-British soldiers demobilized after World War I. Deployed to Ireland in March 1920, most came from English and Scottish cities. While officially they were part of the RIC, in reality, they were a paramilitary force.

On 13 March 1920 during the Kapp Putsch, 12,000 Freikorps soldiers occupied Berlin and installed Wolfgang Kapp, a right-wing journalist, as chancellor.

In March 1920, Tomás Mac Curtain, the Sinn Féin Lord Mayor of Cork, was shot dead in front of his wife at his home, by men with blackened faces who were seen returning to the local police barracks. The jury at the inquest into his death returned a verdict of wilful murder against David Lloyd George (the British Prime Minister) and District Inspector Swanzy, among others. Swanzy was later tracked down and killed in Lisburn, County Antrim. This pattern of killings and reprisals escalated in the second half of 1920 and in 1921.

Hitler was discharged from the army on 31 March 1920 and began working full-time for the NSDAP (National Socialist German Workers Party).
