The United Nations

  • The United Nations (UN) was created in 1945 after the Second World War to help prevent future conflict and encourage cooperation between countries

    • The United Kingdom was a founding member

  • It is based in New York and today has 193 member states

The four main goals of the UN

UN emblem linking four goals: international peace, friendly relations, human rights improvement, and providing a forum for collaborative work.
The UN exists to maintain international peace and security, as well as improve relationships between countries, protect human rights and provide a forum for cooperation

The UN Security Council

  • The UK is one of five permanent members of the UN Security Council, alongside

    • the USA

    • Russia

    • France

    • China

  • Each of these countries has a veto, meaning they can block any Security Council resolution

    • This gives the UK significant influence in international decision-making.

The UK’s influence at the UN

  • As it has a permanent seat on the Security Council, the UK has significant diplomatic influence, even though it has less military and economic power than other leading members

    • This influence, gained through cooperation, diplomacy and reputation, is an example of soft power

  • UK civil servants, experts and non-governmental organisations (NGOs) also contribute to the work of many UN agencies, such as

    • the World Health Organisation (WHO)

    • UNESCO (United Nations Educational, Scientific and Cultural Organisation)

    • UNRWA, the UN agency supporting Palestinian refugees, which is currently in the news because of its work in Gaza

North Atlantic Treaty Organisation (NATO)

  • NATO (the North Atlantic Treaty Organisation) was created in 1949 as a mutual defence alliance

    • The UK was a founding member

  • It was originally formed to protect Western countries from the Soviet Union and other communist states in Europe, which were part of the Warsaw Pact

Membership and defence commitment

  • Today, NATO has 32 member countries

    • Finland joined in 2023

    • Sweden joined in 2024

  • All members agree to support each other if one is attacked

    • This is known as Article 5, the core of the NATO treaty

NATO organisation

  • NATO’s headquarters are in Belgium

  • It has both a military structure and a political structure that work together to coordinate defence and decision-making

  • In October 2024, Mark Rutte, former Prime Minister of the Netherlands, became the Secretary General, the organisation’s senior political leader

NATO and recent events

  • In recent years, the USA has pushed NATO members, including the UK, to increase their defence spending

  • Many NATO countries have recently supported Ukraine in its conflict with Russia by providing

    • military equipment

    • financial assistance

    • training for Ukrainian forces

The Commonwealth

  • The Commonwealth of Nations was created after the Second World War as countries that had once been part of the British Empire became independent

  • Today it has 56 countries, and some of them have no past connection with the UK

    • The Commonwealth contains about 30% of the world’s population

    • Its members include both very rich and very poor countries, and more than 30 of them have populations below 1.5 million

  • Membership is voluntary, so countries can choose whether to join

The Commonwealth in 2025
  • The Commonwealth is guided by a charter, which sets out shared values such as democracy, human rights, equality and development

    • The organisation also provides education, technical support and economic help to its members

  • The UK Monarch is the Head of the Commonwealth,

    • Leading the Commonwealth gives the UK a strong international role and helps it maintain influence across many different parts of the world

  • This leadership also strengthens the UK’s soft power

    • It can build positive relationships, support development projects and increase its global reputation with member countries

Examiner Tips and Tricks

  • A common mistake is assuming the Commonwealth is controlled by the UK

  • Remember that membership is voluntary and decisions are made collectively. Showing that the organisation operates through cooperation, not UK control, helps you avoid over-simplified answers and gain marks

The World Trade Organisation

  • The World Trade Organisation (WTO) was created as the General Agreement on Tariffs and Trade (GATT) after the Second World War to help countries trade fairly

  • Today the WTO has 166 member countries and is based in Geneva, Switzerland.

  • The UK first joined GATT in 1948
