Ingessana (Gaahmg, Tabi) are the members of an African ethnic group of Sudan who speak the Gaam language. They live around the Tabi Hills, southwest of Ad-Damazin and northwest of Kurmuk in the Blue Nile Province. The capital of the Ingessana area is Bao (11.350797,34.083710), and the government offices are in Soda. Subgroups There are 4 major subgroups of the Ingessana: the Jok Kulelek, the Jok Bulek, the Jok Gor, and the Jok Tau. Each of these major subgroups of the Ingessana has an economic specialisation: the Jok Kulelek own great heards of livestock, the Jok Bulek are known for their farming capabilities, the Jok Gor are skilled weavers and the Jok Tau specialise as blacksmiths and iron workers. History As Jedrej (1995) explains, the Gaahmg (Ingessana) have historically protected themselves and their hills from many invasions by outsiders. As a result, their culture is much more resistant to change than that of other ethnic groups of the southern Blue Nile region. Mainly self-sustaining in what they cultivate in the hill area, the Gaahmg are slow to grow cash crops or to migrate for wages. As a result of past conflict with Arabs and other invaders, they have a reputation of being hostile towards strangers and even refugees. Although the origins of the Gaahmg are unclear, the Ingessena hills were alternately raided for several hundred years by the Funj sultans of Sennar to the northwest or by the Abyssinian kings of Gondar to the northeast, the Ingessena hills being a borderland between these kingdoms that plundered for slaves and gold. The Dinka and Nuer to the southwest raided the Gaahmg for cattle during times of drought or flooding in their own areas. From 1820-1855, the ruling Turkish-Egyptian administration demanded heavy tributes of slaves and gold. When they did not receive their demands, they attacked and imprisoned the Gaahmg, taking several hundred prisoners at a time. The Gaahmg fought back with speed and surprise attacks, causing many attacks on them to be unsuccessful. In 1888-1889, the Mahdist government raided the Funj area and the Ingessena hills in particular, to provide for Khartoum during a severe and widespread famine, taking 1000 head of cattle from the Gaahmg on one occasion. The Gaahmg made counter attacks and held Arabs captive for ransom at ten head of cattle per person. From 1903-1934, the Anglo-Egyptian government continued a similar pattern of collecting tribute and squelching
