the 1821 Egyptian conquest of the Funj sultanate of Sennar, in the north of Sudan, and the forcible levying of slaves in Sudan in 1822– 3, led Sudanese slave- owners to revolt.
The indigenous IOA aristocracy did experience crisis, but it had
less to do with anti- slave trade measures, commodity prices, or
superior European military technology, than a combination of misguided domestic policies and environmental factors.

There is clear evidence that the economic and expansionist
policies adopted by the Egyptian and Merina regimes backfired to the
extent that they undermined their economies and caused widespread
domestic hostility to the ruling regime. First, their attempts to industrialise failed. Had they succeeded and a modern industrial sector been created based on free wage labour, the story could have been very different. However, both states relied on the unfree labour of mostly unpaid peasant farmers for their factories and workshops, infrastructural improvements, and cash crop production. Growing peasant animosity to the state- run forced labour regime (called fanompoana in Madagascar) was one of the chief reasons for the failure of the industrial experiment in Egypt and Madagascar. Also economically damaging was the erosion of the traditionally strong artisan class due chiefly to state- imposed, sometimes permanent, corvée labour. This crushed individual enterprise and pushed artisans into abandoning their trades. Most serious of all, a deepening crisis developed in the agricultural sector as peasants were coerced into the army, factories, or other state enterprises, or fl ed the land to avoid forced labour and other taxes.
demands made by Egyptian forces upon nomadic
Arabs in the border region with Ethiopia,north of Khartoum,provoked
revolt by the nomads. Mek Nimmur, one of the nomad leaders, fl ed
to Ethiopia from where, every dry season,he launched cross- border
attacks on Egyptians as, after his death, did his son and namesake.
These confrontations led to much of the Ethiopian borderlands in
Kordofan- Darfur and Darfur- Wadai becoming depopulated and
hence uncultivated. Similarly, Egyptian raids south of Bahr al- Ghazal,
in Sudan, for cattle, ivory, and slaves, aroused great local animosity.
Indeed, due to imperial expansionism, the Egyptian army found
itself increasingly overstretched.
