The region includes four of the biggest Church of Cyprus, which is registered in the list of World Heritage Sites by UNESCO.
In Cyprus some groups exploited these events for personal benefits or revenge and started to use violence against those who did not agree to endorse Christianity.
Epiphanius of Salamis,[4] in order to appease and limit the unacceptable behaviour of this groups, sought support of Emperor Theodosius and with a decree [5] established this mountainous region as a security zone for non-Christians, known back then as the "infidelity area" ("Apistilia" in Greek: η περιοχή των απίστων).
In 653 AD due to the Arab invasion, the area of Pitsilias became the bastion of resistance, its population strengthened by refugees and retreating soldiers.
Mainly because of the small number (10000 Army), and after a few unsuccessful attempts, Rashidun Caliphate drafted a peace treaty with local leaders of Pitsilias avoiding the ravages of guerrilla warfare.
