The Troubles: Ulster loyalist militant Michael Stone attacks a Provisional IRA funeral in Belfast with pistols and grenades. Three persons, one of them a member of PIRA are killed, and more than 60 others are wounded.

The Troubles were an ethno-nationalist conflict in Northern Ireland that lasted for about 30 years from the late 1960s to 1998. Also known internationally as the Northern Ireland conflict, it began in the late 1960s and is usually deemed to have ended with the Good Friday Agreement of 1998. Although the Troubles mostly took place in Northern Ireland, at times violence spilled over into parts of the Republic of Ireland, England, and mainland Europe.

Ulster loyalism is a strand of Ulster unionism associated with working class Ulster Protestants in Northern Ireland. Like other unionists, loyalists support the continued existence of Northern Ireland within the United Kingdom, and oppose a united Ireland independent of the UK. Unlike other strands of unionism, loyalism has been described as an ethnic nationalism of Ulster Protestants and "a variation of British nationalism". Loyalists are often said to have a conditional loyalty to the British state so long as it defends their interests. They see themselves as loyal primarily to the Protestant British monarchy rather than to British governments and institutions, while Garret FitzGerald argued they are loyal to 'Ulster' over 'the Union'. A small minority of loyalists have called for an independent Ulster Protestant state, believing they cannot rely on British governments to support them. The term 'loyalism' is usually associated with paramilitarism.

Michael Anthony Stone is a British former militant who was a member of the Ulster Defence Association, a loyalist paramilitary group in Northern Ireland. He was convicted of three counts of murder committed at an IRA funeral in 1988. In 2000, he was released from prison on licence under the Good Friday Agreement. In November 2006, Stone was charged with attempted murder of Martin McGuinness and Gerry Adams, having been arrested attempting to enter the parliament buildings at Stormont while armed. He was convicted and sentenced in 2008 to a further 16 years' imprisonment, before being released on parole in 2021.
