Signature of the United Nations Charter

On 26 June 1945, 50 states signed in San Francisco the United Nations Charter, which is the foundational treaty of the United Nation. It entered into force four months later, on 24 August 1945 after it has been ratified by the Permanent Members of the Security Council and the majority of the other signatories. Today, 67 years later, 193 countries are members of the United Nation, more then 100’000 peace keepers in 16 different missions are on duty for the United Nations. In the last decades, the General Assembly established several agencies in order to deal with the challenges society is facing, from the United Nations Development Program (UNDP) to the United Nations Children’s Fund (UNICEF) and other specialised agencies.
