Ever since the Arab conquest in 641 Egypt has been ruled by Mohammedans, and for more than half the time by men of Turkish race. Though now and again a strong man has gathered all the reins of control into his own hands and been for a time a personal monarch, as a rule the government has been, till recent years, a military bureaucracy. The people, of course, had no voice in the government. The Egyptians have never been a self-governing race, and such a dream as constitutional democracy was never heard of until a few years ago. By the Arab conquest in the seventh century the people merely changed masters. They were probably not indisposed to welcome the Moslems as their deliverers from the tyranny of the Orthodox Church of the East Roman or Byzantine Empire, invincibly intolerant of the native monophysite heresy; and when the conquest was complete they found themselves, on the whole, better off than before. They paid their taxes to officials with Arabic instead of Greek titles, but the taxes were lighter and the amount was strictly laid down by law. The land-tax of about a pound per acre was not excessive on so fertile a soil, and the poll-tax on nonconformity, of the same amount, was a moderate price to pay for entire liberty of conscience and freedom in public worship guaranteed by solemn treaty. The other taxes were comparatively insignificant, and the total revenue in the eighth century was about £7,000,000. The surplus went to the caliph, the head of the vast Mohammedan empire, which then stretched from Seville to Samarkand, whose capital was first Damascus and afterwards Baghdad. For over 200 years (till 868) Egypt was a mere province of this huge caliphate, and was governed, like other provinces, with a sole view to revenue. "Milk till the udder be dry and let blood to the last drop" was a caliph's instructions to a governor of Egypt. As these governors were constantly changed--there were sixty-seven in 118 years under the Abbasid caliphs of Baghdad--and as a governor's main object was to "make hay while the sun shines," the process of milking the Egyptian cow was often accelerated by illegal extortion, and the governor's harvest was reaped before it was due. Illegality was, however, checked to some extent by the generally wise and just influence of the chief justice, or kadi, whose probity often formed the best feature of the Arab government in Egypt.
