The Conquest of Egypt
Egypt in the last part of the Roman reign: such was their oppression in collecting the various taxes that the people were groaning and craving for a better life in the change of rules . The taxes levied numbered more than twenty , the heaviest of which were the wheat tax , the capitation and the land tax . What made matters worse were the religious disputes accompanied by persecution , all of which caused the ruination of the country . There was a bitter hostility between the national Monophysite of "Jacobite" , and the official "Chalcedonian" (which the curators of Constantinople supported in Egypt) . Cruelly persecuted , the Jacobites looked forward to a change that was to bestow tolerance upon them . Moreover , the standing army was powerless against any foreign invasion . And these conditions combined made the Egyptians welcome the new conquerors .
On crossing the eastern frontiers of Egypt , Amr with his 4 , 000-men-army Arabs met was at Pelusuim (el Farma) where the Roman garrison held out for a month . Again , Amr besieged Belbeis (some thirty miles from Misr) for a month before it surrendered . On his way to the fortress of Babylon , he defeated scanty grouping of the Romans and the rest retreated to a fortress where they could defend themselves for some time . This ancient castle still stands (at least in part) and is known as Kasr-esh-Shema . It was built by Trajan on the site of a Persian fort , and had been fortified by the Romans not long before the Arab invasion .
Before approaching the castle , Amr occupied "Umm Duneyn" (Ezbekiya) , a village lying a little to the north of the fortress . Its possession gave him the command of plenty of boats , and he sent bands of his Arabs up the river to invade the Faiyum Oasis and other parts of Upper Egypt . The Arabs counted on the aid of at least the neutrality of the native Copts , of whose hostility to the Romans Amr had become well
About the middle of June 640 , a big reinforcement of 12 , 000 men under Ez-Zubair Ibn El Awwam , accompanied by several of the companions of the Prophet was sent at Amr's request . He had taken up a position at Heliopolis (on , Ain-Shams) , some miles to the north of Babylon . In July 640 , the Romans were routed with much slaughter at Heliopolis and fled to Babylon .
The Arabs besieged the fortress for eight months and its garrison at last capitulated on April 641 .
Before the battle of Heliopolis , El Mukawkis "Cyrus" (the governor of Egypt and the powerful patriarch of Alexandria) , accompanied by others , opened negotiations with the Arabs with a view to peace . The Arabs offered: conversion to Islam , or the payment of a poll-tax , or war to the knife . The negotiators were willing to submit to the poll-tax , but the Roman garrison utterly refused . When the garrison found the situation critical , they renewed the negotiation and submitted to the poll-tax , provided that the fortress should be left in their hands until Heraclius gave his final decision . Heraclius utterly repudiated this agreement , summoned Cyrus to Constantinople to account for his conduct
1) Those who held their own creed were to pay the poll-tax .
2) It was agreed that the Alexandrians should pay a monthly tribute , and deliver up 150 soldiers and 50 civilians as hostages .
3) The Muslims should not interfere with the churches and affairs of the Christians .
5) The Muslims should hold aloof from Alexandria for 11 months during which the Roman army would leave the city and embark . And they embarked in September 642 .
The Arabs took another year to complete their conquest since they met serious resistance in some towns and provinces . Amr extended his conquest to Libya , because it had been ceded to Egypt during the last period of the Byzantine rule . So , he marched on and captured Cyranaica and Tripoli . His soldiers went southward to the northern frontiers of the Sudan .
The whole of Egypt , up to the borders of the Sudan on the south and Libya on the west , became subject to Muslim domination . Measures were taken to improve the conditions of the peasantry . The land was left in the hands of the cultivators; the old irrigation works were restored and the ancient canal connecting the Mediterranean Sea with the Red Sea was cleared out . The Egyptian Christians (who are called the Copts) were treated with marked favor in consequence of their good will towards the Muslims . Taxation was regulated upon a fixed and moderate scale , and trade was fostered by light customs dues .
