Although the system of governance in the two countries aimed to spread the Islamic message among the peoples and the provincial rulers were fully loyal, the Emirate of Taqali, which came under the influence of Sennar due to its commercial location, was affected by the intense competition between Sennar and Darfur. Or, because the influence of the rulers of Darfur was stronger and more powerful than that of the rulers of Sennar, Taqali sought to improve its relations with Darfur, which angered the Sennar alliance.

The special relations between the Shaigiya and Darfur had an impact on strengthening the position of the Shaigiya themselves, as they were able to break away from the obedience of the Abdallab and also the Funj, rulers of Sennar, and thus entered into a war with the Abdallab.

The transfer of power from the Funj, descendants of Amara Dongus, who took power in 1500 AD until the reign of Sultan Onsa bin Sultan Badi the Red in 1719 AD, saw the throne taken by the house of Ain Shams, who were ministers to the Funj. Thus, the rule of the Funj dynasty lasted from 1500 AD to 1719 AD, more than two centuries. Then the rule of the house of Ain Shams continued from 1720 AD until mid-1821 AD, with the arrival of the Egyptian forces during the reign of Muhammad Ali, the ruler of Egypt under the Turkish Wali. From here, the Sudanese call that invasion.

Chaos prevailed in Sennar after the influence of Darfur began to rise and affect the course of events in Sudan. It can even be said that during the period from 1787 AD to mid-1821 AD, i.e., during thirty-four years, nine kings ruled Sennar, starting with Sultan Awkal, whom Sheikh Nasser appointed. Then after Awkal, Nawwar took over, then Bari, then Ranfi, then Badi, who ruled for twenty-eight years out of the thirty-four years. From this, we can see the extent of the disintegration and chaos that afflicted the country, the breakdown and disruption of water facilities, and the widespread anxiety and fear that led to the increased migration of tribes, especially from the central region of Sudan, which includes the land of
