According to the 1960 Constitution of the Republic of Cyprus (Articles 2 and 3) the Turkish Cypriots are recognised as one of the "Two Communities" of the Republic (alongside the Greek Cypriots). Hence, legally, they have equal power-sharing rights with the Greek Cypriots and are not defined as a "minority group", despite being fewer in numbers (numbering 1,128 in the south of the island in the 2011 census). The Turkish language is an official language of the republic, alongside the Greek language. However, due to the Cyprus crisis of 1963–64, followed by the Greek-led 1974 Cypriot coup d'état and then the 1974 Turkish invasion of Cyprus, the northern half of the island was occupied by Turkey and the Turkish Cypriots declared their own "state" - the Turkish Republic of Northern Cyprus (TRNC), recognized only by Turkey - in 1983. Today it is partly populated by Turkish Cypriots and mostly by Turkish settlers. According to the 2011 "TRNC" census, the population of Northern Cyprus was 286,257. Other estimates suggests that there is between 300,000-500,000 Turkish Cypriots and Turkish settlers living in the north of the island.
