The IRA prisoners in Northern Ireland engaged in protests starting in the 1970s to demand special political prisoner status be reinstated after it was removed. This led to a blanket and later dirty protest. Bobby Sands led two hunger strikes in 1980 and 1981 to pressure the British government, leading to his election as MP while on a hunger strike. Despite international pressure, Prime Minister Margaret Thatcher refused to back down. Sands and nine other prisoners died from starvation, further polarizing nationalists and unionists and strengthening the IRA's position.
