based at Faras, and weaving based at Dongola. Smaller local industries include leatherworking, metalworking, and the widespread production of baskets, mats, and sandals from palm fibre. Also important was the gold mined in the Red Sea Hills to the east of Makuria. Cattle was of great economic importance. Perhaps their breeding and marketing was controlled by the central administration. A great assemblage of 13th century cattle bones from Old Dongola has been linked with a mass slaughter by the invading Mamluks, who attempted to weaken the Makurian economy. Makurian trade was largely by barter as the state never adopted a currency. In the north, however, Egyptian coins were common. Makurian trade with Egypt was of great importance. From Egypt a wide array of luxury and manufactured goods were imported. The main Makurian export was slaves. The slaves sent north were not from Makuria itself, but rather from further south and west in Africa. Little is known about Makurian trade and relations with other parts of Africa. There is some archaeological evidence of contacts and trade with the areas to the west, especially Kordofan. Additionally, contacts to Darfur and Kanem-Bornu seem probable, but there are only few evidences. There seem to have been important political relations between Makuria and Christian Ethiopia to the south-east. For instance, in the 10th century, Georgios II successfully intervened on behalf of the unnamed ruler at that time, and persuaded Patriarch Philotheos of Alexandria to at last ordain an abuna, or metropolitan, for the Ethiopian Orthodox Church. However, there is little evidence of much other interaction between the two Christian states.
