The 1920 Cork hunger strike begins which eventually results in the deaths of three Irish Republicans including the Lord Mayor of Cork Terence MacSwiney.

The 1920 Cork hunger strike occurred in late 1920, during the Irish War of Independence, when 65 men interned without trial in Cork County Gaol went on hunger strike, demanding release from prison, and reinstatement of their status as political prisoners. Beginning on 11 August 1920, they were joined the following day by the Lord Mayor of Cork, Terence MacSwiney. A week into the hunger strike, all but 11 of the hunger strikers were released or deported to prison in England, with MacSwiney being among the latter.

Irish republicanism is the political movement for an Irish republic, void of any British rule. Throughout its centuries of existence, it has encompassed various tactics and identities, simultaneously elective and militant and has been both widely supported and iconoclastic.

Terence James MacSwiney was an Irish playwright, author and politician. He was elected as Sinn Féin Lord Mayor of Cork during the Irish War of Independence in 1920. He was arrested by the British Government on charges of sedition and imprisoned in Brixton Prison. His death there in October 1920 after 74 days on hunger strike brought him and the Irish Republican campaign to international attention.

August 11 is the 223rd day of the year in the Gregorian calendar; 142 days remain until the end of the year.
