Perhimpoenan Indonesia or PI (English: Indonesian Association; Dutch: Indonesische Vereeniging) was an Indonesian student association in the Netherlands in the first half of the twentieth century. It was established under the Dutch name Indische Vereeniging (English: Indies' Association; Malay/Indonesian: Perhimpoenan Hindia). It later changed its name to Indonesische Vereeniging (Indonesian Association) in 1922, and its Malay translation Perhimpoenan Indonesia in 1925. Although small in membership numbers – throughout the period between 30 and 150 members – the organization was important because it was one of the first to campaign for full Indonesian independence from the Netherlands, and because many PI-students would later acquire prominent political positions in the independent state of Indonesia.[1]
