The flag of the Council of Europe is the banner of Europe's oldest and largest pan-European intergovernmental body, founded in 1949 in the aftermath of the Second World War. The Council's remit covers human rights, democracy, and the rule of law, and it operates the European Court of Human Rights.
The flag of the Collective Security Treaty Organisation is the banner of the post-Soviet military alliance formed by treaty in 1992 and reorganised under its current name in 2002. The CSTO operates as a mutual-defence pact among its member states.
The flag of the World Trade Organization is the banner of the global trade body founded in 1995 to succeed GATT. The simple emblem-on-blue design echoes the visual conventions of UN-family agencies, distinguishing the organisation from purely sovereign symbols.
The flag of the Organisation for Economic Co-operation and Development is the banner of the policy forum and statistical agency for the world's mostly high-income democracies. Founded in 1961 as successor to the Marshall Plan's OEEC, the OECD's visual identity has been refreshed several times — most recently in 2020.
The flag of the Asia-Pacific Economic Cooperation forum is the banner of the regional economic body linking 21 economies bordering the Pacific. Adopted shortly after APEC's 1989 founding, the emblem signals the bloc's pan-Pacific scope without the heraldic baggage of national symbols.
The flag of the European Free Trade Association is the banner of the four-country trade bloc — Iceland, Liechtenstein, Norway, and Switzerland — founded in 1960 as a counterweight to the European Economic Community. Where EFTA once linked nine European economies, three (Austria, Finland, Sweden) departed for the EU and one (the UK) had left earlier.
The flag of the Organization for Security and Co-operation in Europe is the banner of the world's largest regional security body, with 57 participating states from Vancouver to Vladivostok. The flag was adopted in 1995 when the Conference on Security and Co-operation in Europe (CSCE, founded 1975) was renamed and given permanent institutions.
The flag of the International Criminal Police Organization is the banner of the worldwide police-cooperation body founded in Vienna in 1923. The emblem combining globe, scales, and olive branches was adopted in 1950 and has been the organisation's visual identity ever since, surviving two reorganisations (1956, 1989) without redesign.
The flag of the International Atomic Energy Agency is the banner of the global nuclear watchdog established in 1957 in response to US President Eisenhower's 1953 "Atoms for Peace" speech. The emblem combining atomic symbol with olive branches captures the agency's dual mandate: promoting peaceful nuclear applications while preventing weapons proliferation.
