Provisional IRA in the Republic of Ireland
The Provisional IRA in the Republic of Ireland was very active in the country during the Troubles (1969–1998). The country was seen as a safe haven for IRA members who used it to flee from British security forces, organise training and homemade weapons, and conduct attacks on British or Loyalist targets in nearby Northern Ireland, England, and even continental Europe.
