Ethiopian–Ottoman border conflict

The Ethiopian–Ottoman border conflict was an undeclared war between the Ottoman province of Egypt and various Ethiopian warlords occurring soon after the Egyptian conquest of Sudan. By the middle of the 19th century, the Ethiopians and Turco-Egyptians faced each other across an undefined and contested border. Muhammad Ali initially entertained the idea of conquering all of Tigray and Amhara, but by the middle of the 19th century Egypt had only limited objectives in Ethiopia, namely to establish its authority over the mineral rich slopes of the Ethiopian peripheral areas.
