Why do you think the Berbers resented being ruled by the Arabs, even though they had converted to their religion?

The Berbers resented being ruled by the Arabs because they decided not to quietly accept the domination of the Arabs. This is as a result of the ban on "Anciet Berber Poetry" which led to open revolt and riot in Kabyle in 1980 - 1981. The Berbers saw this as a suppression of their Berber culture and an attempt to efface the Berber historical memory. They could not take it any longer, so riot broke out.

Even when the Berbers were converted to Muslims, the Arabs treated them like second-class muslims and heavily taxed and even enslaved them. All these led to the resentment by the Berbers against the domination and rulership by the Arabs.

Because they were treated by the Arabs as second-class Muslims, heavily taxed, and even enslaved.

Explanation:

In North Africa, most especially Algeria, the population was majorly of Berber origin, and additionally with those who followed traditional Berber religious practices.

However, when the Arabs swept in, invaded and conquer the region in the seventh century, subjugating the Berbers, they brought with them an Islam that replaced traditional practices and Christianity.

Alas, even after many Berbers converted, they were treated by the Arabs as second-class Muslims, heavily taxed, and even enslaved.

Hence, this made the Berbers resented being ruled by the Arabs, even though they had converted to their religion.
