In 1925, Britain declared Cyprus a crown colony. In the years that followed, the determination of Greek Cypriots to achieve "enosis" continued. In 1931 this led to open revolt. A riot resulted in the death of six civilians, injuries to others and the burning of Britain's Government House in Nicosia. In the months that followed, about 2,000 people were convicted of crimes in connection with the struggle for union with Greece. Britain reacted by imposing harsh restrictions. Military reinforcements were dispatched to the island and the constitution suspended. A special "epicourical" (reserve) police force was formed consisting of only Turkish Cypriots, press restrictions instituted and political parties banned. Two bishops and eight other prominent citizens directly implicated in the conflict were exiled. Municipal elections were suspended, and until 1943 all municipal officials were appointed by the government. The governor was to be assisted by an Executive Council, and two years later an Advisory Council was established; both councils consisted only of appointees and were restricted to advising on domestic matters only. In addition, the flying of Greek or Turkish flags or the public display of portraits of Greek or Turkish heroes was forbidden.
