Unrra

 UNRRA stands for United Nations Relief and Rehabilitation Administration.

It was established in November 1943, before the formal creation of the United Nations, by 44 Allied nations during World War II. Its mission was to provide emergency relief to people devastated by the war. 

Its major responsibilities included:

Providing food, clothing, fuel, and shelter.

Delivering medical care and helping control disease.

Assisting millions of refugees and displaced persons to return home.

Supplying farm equipment, seeds, and tools to help restart agriculture.

Supporting the reconstruction of war-torn communities. 

UNRRA operated from 1943 to 1947 (with final wind-up completed shortly afterward). Many of its responsibilities were later transferred to organizations such as the World Health Organization and the International Refugee Organization. 

UNRRA is remembered as one of the first large-scale international humanitarian relief efforts and laid the foundation for many of the humanitarian agencies that followed.
