The inhabitants of Nubia, then turning west to Wadi al-Aalaqi, reached the region of Shangeer, near the bend of the Nile to the west, close to the kingdom of Al-Abwab, where he discovered new sites of gold cities. He realized that this area was part of the region of Al-Rabtab and Al-Asir, where he established new bases to obtain water for settlement after discovering new sites for mining and overcoming the forces of "George I," the king of Nubia. Then he moved north when he heard that some tribes from Sham had revolted against him after they had settled in the area of Adandan, in agreement with the Nubians. His area of influence expanded to the area of Aidhab to the east, and its northern borders were Aswan. Ibn Tulun feared for himself from the expansion of Al-Amri's influence and sent an army to fight him. Ibn Tulun's armies were defeated by Al-Amri, and he moved north to Edfu. However, he decided to return to his area of influence in the mines. The tribe of Rabia attacked him and fought him, but he defeated them. Al-Amri aimed to establish an independent principality from Ibn Tulun in that vast region south of Aswan, after he had settled in an area near the Fila mine in Egypt. Then he parted from them after a dispute over the Shanka mine, which is thought to be near Umm Nabardi or Wadi Hamd Qalib. However, Al-Amri did not find enough water for mining operations in that mine. The Nile flooded, and its people prevented him from it, suspecting his intentions. But Al-Amri attacked the inhabitants of Shangeer, the region located between Abu Ahmed and Berber, and captured a large number of them, whom he sold in the markets of Egypt. His wealth increased, and his authority grew, and caravans began to arrive at his camp laden with provisions. However, his leadership did not last long, as he entered into long wars with Nubia. Sa'd al-Ashira accused him of collaborating with Ailan, and finally, Al-Amri was forced to move north and encamp near Aswan, although this was after he had extended his influence over the tribes of Juheina, Rabia, and Sa'd al-Ashira. His influence and authority grew to such an extent that it is mentioned that sixty thousand camels were used to transport provisions from Aswan to his allies, in addition to the supplies that came from Aidhab. Ibn Tulun had thought of taking revenge on Al-Amri, but he preferred safety after his initial defeat against Al-Amri's forces. 64
