In the 18th, 19th, and early 20th centuries, a wide variety of resistance movements across Asia and Africa fought against European imperialism. These movements reflected a range of organizational principles, from traditional kingdoms to religious movements to guerrilla nationalists.

India's independence movement and revolts in Sudan.

Explanation:

These two campaigns are fought in all factors. The riots in Sudan were triggered by religion and brought out by violent processes. France had authority in Sudan, and the organizers of the faith-sponsored campaign attempted to overcome French rule. On the other hand, the old Indian freedom movement was not on a violent pathway. Civil disobedience, nonviolent protests were the main techniques of resistance. India's independence campaign is promoted by ethnicity and nationalism. So one campaign used violent and militant ways, while the other campaign used revolution and patriotism.
