It is thought that the conquest of the Sudan by Muhammad Ali was motivated primarily by the legendary gold of the Sudan and by the need for manpower for the newly formedNizam-I-Jadid(the new army). Because of Egypt's involvements in Syria and Arabia in the 1830s, the need for more funds and manpower for the army had increased considerably. The most promising areas for minerals, trade, and slave hunting bordered on the Ethiopian plateau. Those areas were inhabited by a mixed Hamitic and Negroid population, many of whom were Muslims and pagans. These people, although in many cases they did not realize it, were considered by some of the Ethiopian border lords to be their subjects, since the Ethiopian concept of a border was not that of a dividing line but of undefined areas stretching into their neighbours' lands.The situation in Ethiopia in the first half of the nineteenth century was generally conducive to an Egyptian conquest. The internal wars which had been gaining momentum ever since the middle of the eighteenth century expedited the fragmentation of the country, weakened most of the important provincial rulers, and exhausted the population. The revival of Islam in the beginning of the nineteenth century had an immediate impact upon Ethiopia. Islam was spread in the interior by the trading caravans monopolized by Muslim merchants, and found many followers among the Galla tribes of Ethiopia. Moreover, the actual rulers of the country were the Galla chiefs who had been the guardians of the puppet emperors in Gondar since the end of the eighteenth century; and as they feared the growing pressure of Tigrean and Amhara Christian lords, they were ready, if necessary, to invite the Egyptians to enter Ethiopia. However, the reappearance of European powers in the Red Sea at the beginning of the nineteenth century not only facilitated the acquisition of quantities of firearms by Tigrean and Amhara lords, but above all curbed the expansionist tendencies of Egypt in the direction of Ethiopia. Thus, until the middle of the nineteenth century Egypt had only limited objectives in Ethiopia, namely to establish its authority over the mineral-rich areas on the slopes of the Ethiopian plateau and to control the caravan routes and the outlets of the seemingly rich Ethiopian trade. Nevertheless, the ground was prepared for the clash between Egypt and Ethiopia in the period of Khedive Ismail.
