Armenians have had a continuous documented presence in Cyprus since 578 AD: according to historian Theophylact Simocatta, during his campaign against the Persian King Chosroes I, Byzantine General Maurice the Cappadocian captured 10,090 Armenians as prisoners in Arzanene, of whom about 3,350 were deported to Cyprus. More Armenians arrived during the reign of Armenian-descended Emperor Heraclius for political reasons and also during the pontificate of Catholicos Hovhannes III Odznetsi for commercial reasons. Flowing on, after the end of Arab raids in Cyprus, more arrived by the patrician Niketas Chalkoutzes for military reasons, when Armenian mercenaries were transferred to Cyprus to protect it. In the middle Byzantine period, Armenian generals and governors served in Cyprus, like Alexios Mousele or Mousere who undertook the construction of Saint Lazarus' basilica in Larnaca. It appears that Saint Lazarus' church had been an Armenian Apostolic church in the 10th century and was used by Armenian-Catholics during the Latin Era as well. The numerous Armenians required an analogous spiritual pastorate, and so in 973 Catholicos Khatchig I established the Armenian Bishopric in Nicosia. Relations between Cyprus and the Armenians became closer when the Kingdom of Cilicia was established. Between 1136-1138, Byzantine Emperor John II Comnenus moved the entire population of the Armenian city of Tell Hamdun to Cyprus. After Isaac Comnenus' wedding to the daughter of the Armenian prince Thoros II in 1185, Armenian nobles and warriors came with him to Cyprus, many of whom defended the island against Richard the Lionheart, when he landed in Limassol.
