When Indonesia occupied East Timor between 1975 and 1999, declaring it "the Republic's 27th Province", the use of Portuguese was banned, and Indonesian was declared the sole official language, but the Roman Catholic Church adopted Tetum as its liturgical language, making it a focus for cultural and national identity. After the United Nations Transitional Administration in East Timor (UNTAET) took over governance in September 1999, Tetun (Dili) was proclaimed the country's official language, even though according to "Encarta Winkler Prins" it was only spoken by about 8% of the native population at the time, while the elite (consisting of 20 to 30 families) spoke Portuguese and most adolescents had been educated in Indonesian. When East Timor gained its independence on 20 May 2002, Tetum and Portuguese were declared as official languages. The 2010 census found that Tetum Prasa had 385,269 native speakers on a total population of 1,053,971, meaning that the share of native Tetum Prasa/Dili speakers had increased to 36.6% during the 2000s.
