Hillsborough’s Uneasy Promise
Archived: 26 September 2026
In 1985, the Anglo-Irish Agreement, signed by Garret FitzGerald and Margaret Thatcher at Hillsborough, created a permanent consultative role for Dublin in Northern Ireland affairs while confirming majority consent for constitutional change. It offered constitutional nationalists progress but provoked unionist protest and Fianna Fáil opposition. Violence continued, including major IRA attacks and the killing of a Garda officer. Sinn Féin advanced electorally and revised its Dáil abstention policy. The Republic faced severe unemployment and emigration, alongside the Progressive Democrats’ foundation and liberalised contraception law. Religious controversy, theatre, U2’s Croke Park concert and Cork 800 reflected changing national identities amid hardship.
