  • Summit meetings are often held at key moments in the Alliance's evolution – they are not regular meetings, but important junctures in the Alliance's decision-making process.
  • Summits are used, for instance, to introduce new policy, invite new members into the Alliance, launch major initiatives and reinforce partnerships.
  • They are meetings of the North Atlantic Council at its highest level possible – that of Heads of State and Government.
  • Since 1949, there have been 32 NATO summits (see the full list below); the last one was in June 2022 in Madrid, Spain. The next will be in July 2023 in Vilnius, Lithuania.
  • NATO summits are always held in a NATO member country and are chaired by the NATO Secretary General.

Summit meeting agendas

NATO summit meetings are effectively meetings of the North Atlantic Council (NAC) - the Alliance's principal political decision-making body - at its highest level, that of Heads of State and Government.

Due to the political significance of summit meetings, agenda items typically address issues of overarching political or strategic importance. Items can relate to the internal functioning of the Alliance as well as NATO's relations with external partners.

Major decisions

Many of NATO's summit meetings can be considered as milestones in the evolution of the Alliance. For instance, the first post-Cold War summit was held in London, in 1990, and outlined proposals for developing relations with Central and Eastern European countries. A year later, in Rome, NATO Heads of State and Government published a Strategic Concept that reflected the new security environment. This document was issued as a public document for the first time ever. At the same summit, NATO established the North Atlantic Cooperation Council – a forum that officially brought together NATO and partner countries from Europe, Central Asia and the Caucasus.

The 1997 Madrid and Paris Summits invited the first countries of the former Warsaw Pact – Czechia, Hungary and Poland – to join NATO, and established partnerships between NATO and Russia and Ukraine, while the 2002 Prague Summit saw major commitments to improving NATO's capabilities and transformed the military command structure.

Under exceptional circumstances, the Alliance has applied exceptional measures: following Russia's unprovoked attack on Ukraine, which started on 24 February 2022, NATO leaders held an extraordinary virtual summit on 25 February from NATO Headquarters, Brussels. This was shortly followed by an extraordinary summit meeting on 24 March where NATO Heads of State and Government met to address the consequences of Russia's invasion of Ukraine and take measures to further strengthen NATO's deterrence and defence. These are just a few of the many decisions that have been taken over the decades (a full summary of all NATO summit meetings can be found below under "Previous summit meetings").

Implementation of summit decisions

Typically, the decisions taken at a summit meeting are issued in declarations and communiqués. These are public documents that explain the Alliance's decisions and reaffirm Allies' support for aspects of NATO policies.

The decisions are then translated into action by the relevant actors, according to the area of competency and responsibility: the NAC's subordinate committees and NATO's command structure, which cover the whole range of the Organization's functions and activities.


Timing and location


Summits are convened upon approval by the NAC at the level of Permanent Representatives (or Ambassadors) or foreign and defence ministers. They are usually called on an ad-hoc basis, as required by the evolving political and security situation.

From the founding of NATO until the end of the Cold War – over 40 years – there were 10 summit meetings. Since 1990, their frequency has increased considerably in order to address the changes brought on by the new security challenges. In total, 32 summits have taken place since 1949, as well as a number of leaders' or special meetings (London, December 2019; the inauguration of the new headquarters, Brussels, May 2017; the visit of the newly elected President of the United States, Brussels, June 2001). 


NATO summit meetings are held in one of the member countries, including Belgium, at NATO Headquarters. Members volunteer to host a summit meeting and, after evaluating all offers, the NAC makes the final decision concerning the location.

In recent times, summit locations have held some thematic significance. For example, the Washington Summit of 1999 commemorated the 50th anniversary of the signing of the North Atlantic Treaty in that city. Istanbul – which hosted a summit meeting in 2004 – connects Europe and Asia and is where the Alliance launched the Istanbul Cooperation Initiative. This initiative is intended to foster linkages between NATO and the broader Middle East.


Previous summit meetings

The first time that Heads of State and Government from NATO countries met was at the actual signing ceremony of the North Atlantic Treaty on 4 April 1949, but this was not a summit meeting. The first summit meeting was held eight years later, in Paris in 1957. Subsequent summits have since occurred at key junctures in the history of the Alliance.

Madrid, 29-30 June 2022
NATO leaders adopted a new Strategic Concept, agreed a more proactive posture to bolster responsiveness, readiness and combat power, and took measures to strengthen NATO's deterrence and defence in the long term. In the context of Russia's war on Ukraine, they reiterated NATO's continued support to Ukraine and to other partners at risk. They reaffirmed NATO's Open Door Policy and officially invited Finland and Sweden to join NATO. They engaged with partners in the Indo-Pacific region to increase cooperation and focused on challenges from the south, including terrorism and the world food crisis caused by Russia's war on Ukraine. Allies committed to investing more in defence, to boosting resilience and to integrating cross-cutting issues such as technological innovation, climate change, human security and Women, Peace and Security across the Alliance's core tasks.

Brussels, 24 March 2022
Addressing the consequences of Russia's unprovoked war on Ukraine, Allied leaders agreed to reset NATO's longer-term deterrence and defence posture across all domains - land, sea, air, cyber and space. They reaffirmed the unity and resolve in their determination to oppose Russia's aggression, aid the government and people of Ukraine, and defend the security of all Allies.

Virtual extraordinary summit, 25 February 2022
NATO leaders unanimously condemned Russia's full-scale invasion of Ukraine - the gravest threat to Euro-Atlantic security in decades - and reiterated their support to Ukraine. They also stated that they would make all deployments necessary to ensure strong and credible deterrence and defence across the Alliance, now and in the future.

Brussels, 14 June 2021
NATO leaders agreed a set of proposals under the NATO 2030 reform agenda to strengthen the Alliance as a forum for political consultations; reinforce collective defence through increased readiness, modernised capabilities and more investment; and develop Alliance-wide resilience objectives to make societies less vulnerable to attack and coercion. A plan to boost transatlantic innovation, including with a new "defence accelerator" to foster cooperation, was adopted, as well as measures to uphold the rules-based international order, such as deepening partnerships and plans to step up training and capacity-building for partners. Leaders also agreed to address the security consequences of climate change and develop NATO's next Strategic Concept in time for the next summit in 2022.

Brussels, 11-12 July 2018
Three principal issues: reinforcing the Alliance's deterrence and defence, stepping up the fight against terrorism and fairer burden-sharing between NATO members.  Decisions were taken on raising the readiness of NATO forces, modernising the military command structure and setting up a cyberspace operations centre and counter-hybrid support teams. Leaders remained committed to a dual-track approach to Russia – defence and dialogue – and addressed challenges from the Middle East and North Africa. NATO launched a new training mission in Iraq and offered more support to Jordan and Tunisia. The financing for Afghan security forces was also extended until 2024. The government of Skopje was invited for accession talks to become NATO's 30th member.

Organising and holding these events

NATO summit meetings are centred on the activities of the North Atlantic Council (NAC or Council). As with all NAC meetings, the Secretary General chairs them and plays an important role in coordination and deliberations to help members reach consensus on the issues at hand.

As with meetings at the levels of Permanent Representatives and ministers, the work of the NAC is prepared by subordinate committees with responsibility for specific areas of policy. The Deputies Committee, which consists of Deputy Permanent Representatives, is responsible for drafting declarations and communiqués after meetings of heads of state and government, as well as foreign and defence ministers.

Other aspects of political work may be handled by the Political Committee and the Partnerships and Cooperative Security Committee. Depending on the topic under discussion, the respective senior committee with responsibility for the subject assumes the lead role in preparing Council meetings and following up Council decisions.

Support to the Council is provided by the Secretary of the Council, who is also Director of the ministerial and summit meeting task forces. The Secretary of the Council ensures that NAC mandates are executed and its decisions recorded and circulated. A small Council Secretariat ensures the bureaucratic and logistical aspects of the Council's work, while the relevant divisions of the International Staff support the work of committees reporting to the NAC.



NATO summit meetings normally involve member countries only. However, on occasion, and provided Allies agree, meetings can be convened in other formats. They include, for instance, meetings of defence ministers and foreign ministers or meetings of heads of state and government from partner countries.  They can also include leaders from countries contributing troops to a NATO-led operation, as was the case for ISAF troop-contributing countries at the 2010 Lisbon Summit or top representatives from international organisations such as the United Nations, the European Union or the World Bank.
