In the aftermath of the First World War (1914 – 1918), millions of people fled their homelands in search of refuge. Governments responded by drawing up a set of international agreements to provide travel documents for these people who were, effectively, the first recognized refugees of the 20th century. Their numbers increased dramatically during and after the Second World War (1939-1945), as millions more were forcibly displaced.
In response, the international community steadily assembled a set of guidelines, laws and conventions aimed at protecting the basic human rights and treatment of people forced to flee conflict and persecution.
The process, which began under the League of Nations in 1921, culminated in the 1951 Convention which consolidated and expanded on previous international instruments relating to refugees and continues to provide the most comprehensive codification of the rights of refugees at the international level.
