 Fearing that the Rûm of Syria might aid the Greek Revolution, the Porte issued an order that they should be disarmed.In Jerusalem, the city's Christian population, who were estimated to make up around 20% of the city's total (with the majority being Rûm), were also forced by the Ottoman authorities to relinquish their weapons, wear black, and help improve the city's fortifications.Greek Orthodox holy sites, such as the Monastery of Our Lady of Balamand, located just south of the city of Tripoli in Lebanon, were subjected to vandalism and revenge attacks, which in fact forced the monks to abandon it until 1830.
