Britain took advantage of the Egyptian-Turkish crisis in 1839 AD, and the issue ended with the intervention of its forces in Syria, and Muhammad Ali was forced to withdraw from all the provinces he seized following the conclusion of the London Treaty of 1840 AD between the Ottoman Empire and the four European, powers (Britain, Russia, Austria and Prussia) this study clarified the effects of the issuance of the firman 1841AD and its results limiting his forces ,restricting his authority in Egypt within its natural borders and some areas in Palestine and to abide by the conditions of the Ottoman Sultan's Farman, which led to the weakness of Muhammad Ali as the mentioned countries gave themselves the right to intervene in future to protect this province against any Ottoman interference, which means that the successors of Muhammad Ali pasha must rely on full European support to preserve the independence of their province in the future.
