of the United Nations. 82% of the participants voted for complete independence from the Netherlands. Tensions mounted as Croes stepped up the pressure on the Dutch government by organising a general strike in 1977. Croes later met with Dutch Prime Minister Joop den Uyl, with the two sides agreeing to assign the Institute of Social Studies in The Hague to prepare a study for independence, entitled Aruba en Onafhankelijkheid, achtergronden, modaliteiten, en mogelijkheden; een rapport in eerste aanleg (Aruba and independence, backgrounds, modalities, and opportunities; a preliminary report) (1978). Autonomy In March 1983, Aruba reached an official agreement within the Kingdom for its independence, to be developed in a series of steps as the Crown granted increasing autonomy.
