At first of course there was a brief period of confusion, some burning, pillaging, massacring; but this was soon checked by the Arab governors. When things had settled down again, the subject populations found themselves at least no worse off than before, and they shortly began to perceive that they had benefited by the change of rulers. They were permitted to retain their own laws and judges; governors of their own race administered the districts, collected the taxes, and determined such differences as arose amongst themselves. The citizen classes, instead of bearing the whole burden of the State expenditure, had only to pay a poll-tax of no very exacting amount, and they were free of all obligations; unless they held cultivable land, in which case they paid the _Kharaj_ or land-tax as well. The poll-tax was graduated according to the rank of the payer, from twelve to forty-eight _dirhems_ a year, or from about three to twelve pounds at our present purchasing power of money; and its collection in twelve monthly instalments made it the easier to meet. The poll-tax was an impost upon heresy; it was levied only upon Christians and Jews: the land-tax, on the other hand, which varied according to the productiveness of the soil, was assessed equally on Christians, Jews, and Moslems. As a rule the old proprietors and cities preserved their property as before the conquest. The lands of the Church, indeed, and of those landowners who had fled to the mountains of the north, were confiscated, but even then their serfs were left upon them as cultivators, and were only required to pay a certain proportion, varying from a third to four-fifths, of the produce, to their new Moslem lords. Sometimes the cities, such as Merida and Orihuela, had been able to obtain exceptionally favourable terms from the conquerors, and were suffered to retain their goods and lands upon the payment of a fixed tribute. At the worst, beyond the poll-tax, the Christians were in no way subject to heavier exactions than their Moslem neighbours. They had even gained a right which had never been permitted them by the Gothic kings: they could alienate their lands.[7] In religious toleration they had nothing to regret. Instead of persecuting them, and forcing upon them a compulsory conversion, as the Goths had upon the Jews, the Arabs left them free to worship whom or what they pleased; and so valuable was the poll-tax to the treasury, that the Sultans of Cordova were much more disposed to discourage than to welcome any considerable missionary fervour that might deprive the State of so useful a source of revenue. The result was that the Christians were satisfied with the new _régime_, and openly admitted that they preferred the rule of the Moors to that of the Franks or Goths. Even their priests, who had lost most of all, were at first but little incensed with the change, as the old chronicle, ascribed to Isidore of Beja, written at Cordova in 754, shows.
