From the summer of 1909 onwards the nature of the rebellions in Macedonia changed. The Christian communities largely ceased their rebellious activities while the Albanians, who were 70% Muslim and until that time had been the most loyal group in Macedonia, now started to rebel against the Ottoman state. Until that time, it had always been assumed by the Unionists that Islam would ensure the loyalty of the Muslim Albanians, so the frequent Albanian revolts came as a surprise. The decision to impose Turkish as the language in schools together with another law announcing that Albanian could only be written in the Arabic alphabet while the majority of Albanians had wished to adopt the Latin alphabet. After crushing one Albanian revolt in 1909, another one broke out in March 1910. The uprising had been crushed by the autumn, many Albanian nationalists were executed and a systematic attempt was being made to crush Albanian nationalism by banning Albanian newspapers and private schools. In March 1911, yet another Albanian revolt broke out, but this time, the government chose negotiation by sending the sultan Mehmed V to tour Macedonia in June 1911 and proclaim an amnesty for those Albanian rebels who agreed to lay down their arms. The Italian invasion of Libya came as another blow against the country.
