The town traces its origins to the 18th century, when a colony of Tukrir from Darfur finding the spot a convenient resting-place for their fellow-pilgrims on their way to Mecca and back, obtained permission from the Emperor of Ethiopia to make a permanent settlement there. However Hormuz Rassam records a different account, stating "within the last century" the rulers of Metemma were in constant war with their counterparts at Er-Rashid and manned their armies with slaves taken from Kurdufan and Darfur. These foreign conscripts eventually revolted and killed the "so-called Arab chief", making one of their number ruler. Lying on the main trade route from Sennar to Gondar, Metemma/Gallabat grew into a trade center of some importance. The Scottish explorer James Bruce travelled through the town in 1772. This location not only made the settlement a major marketplace, but also a major slave market in the 19th century. Richard Pankhurst has published estimates of the number of people sold in this market during the 19th century that range between 10,000 and 20,000. By 1881, European visitors reported that the Emperor Yohannes IV had ordered the slave market closed. Emperor Yohannes was killed in battle nearby on 9–10 March 1889 fighting the Sudenese Mahdist in the Battle of Gallabat. An Italian column from Gadabi occupied Metemma on 12 April 1936, which consisted of one Eritrean battalion, one squadron mounted on camels, and 1 platoon of light tanks. During the occupation, the Italians built a mosque in the town. After war was declared between the British and Italian Empires, the Italians crossed the border and occupied Gallabat. But the British recaptured the town 6 November 1940 with the intent of then capturing Metemma; however, the attack on Metemma failed miserably and the British were forced to evacuate Gallabat again. They occupied Metemma for good 19 January 1941. The trade route through Metemma remained important up to the beginning of the 20th century, but the introduction of rail transport to Sudan, as well as improvements to the roads inside Ethiopia robbed the town of its importance, until by E.C. 1944 an official survey found only 129 thatched and corrugated-roof houses in Matemma, of which "fourteen were government properties, three were owned by nagades and twelve were empty -- probably reserved for renting." During the Ethiopian Civil War, Metemma was captured by the Ethiopian Democratic Union on 13 January 1977, who attacked from positions inside Sudan. The town was taken from the EDU by the Ethiopian People's Revolutionary Democratic Front 7 October 1990, claiming to have killed 28 of its enemy forces, wounded 21, and captured 16. A road toAl Qadarif of good standard was completed mid-March 2002, allowing import and export goods to be sent through Port Sudan, where an area had been reserved for Ethiopian goods and containers.
