The Nineteenth Amendment of the Constitution is an amendment of the Constitution of Ireland which permitted the state to be bound by the British–Irish Agreement and enabled the establishment of shared political institutions between Ireland and Northern Ireland. It also provided a mechanism for a further amendment to the Constitution upon a declaration by the government on the implementation of the Agreement, most notably by changing Articles 2 and 3 from the previous claim over the whole island of Ireland to an aspiration towards creating a united Ireland by peaceful means, "with the consent of a majority of the people, democratically expressed, in both jurisdictions in the island".
Ireland is one of four members of the European Union that are not members of NATO. The others are Austria, Cyprus and Malta. The country has a longstanding policy of military neutrality: it does not join military alliances or defence pacts, or take part in international conflicts. The nature of Irish neutrality has varied over time. Ireland declared itself a neutral state during the Second World War, and during the Cold War it did not join NATO nor the Non-Aligned Movement. Since the 1970s, some have defined it more broadly to include a commitment to "United Nations peacekeeping, human rights and disarmament". Recent Irish governments have defined it narrowly as non-membership of military defensive alliances. The compatibility of neutrality with Ireland's membership of the European Union has been a point of debate in EU treaty referendum campaigns since the 1990s. The Seville Declarations on the Treaty of Nice acknowledge Ireland's "traditional policy of military neutrality". The Irish Defence Forces have been involved in many UN peacekeeping missions.

It was approved by referendum on 11 June 2004 and signed into law on 24 June of the same year. It affected in part changes made to the Constitution by the Nineteenth Amendment of the Constitution of Ireland which was passed as part of the Good Friday Agreement.
This is a list of referendums related to the European Union, or referendums related to the European Communities, which were predecessors of the European Union. Since 1972, a total of 48 referendums have been held by EU member states, candidate states, and their territories, with several additional referendums held in countries outside the EU. The referendums have been held most commonly on the subject of whether to become a member of European Union as part of the accession process, although the EU does not require any candidate country to hold a referendum to approve membership or as part of treaty ratification. Other EU-related referendums have been held on the adoption of the euro and on participation in other EU-related policies.
