From that period to the middle of the present century, the kingdom maintained its Independence; but at the latter æra, the Bashaw of Tripoli invaded it with a powerful force, laid siege to the capital, defeated, and took captive the King, and carried him a prisoner to Tripoli. For two years the unfortunate Monarch was detained in bondage, but at the end of that period, on the condition of an annual tribute of fifty slaves and ten pounds of gold dust, the Bashaw restored him to his Crown. Till the accession of the present King of Fezzan, this tribute was faithfully transmitted; but the reigning Sovereign, conscious of the declining power of Tripoli, and of the internal strength which the affection and confidence of his people had given to his Kingdom, has gradually diminished the amount, and altered the nature of the acknowledgement; for it now consists in an occasional present of a few slaves, and of a pound or two of gold dust, and is rather the compliment of a trading State to the Kingdom in which its principal commodities are sold, than a proof of political dependence. Still, however, the expression of _my_ Kingdom of Fezzan is in frequent use with the reigning Bashaw of Tripoli, who is the grandson of the Conqueror; nor has the dependence of the former State on the latter been ever directly renounced.[7] In Fezzan, as in all the Countries in which the Mahometan Faith is established, the descendants of the Prophet are considered as a distinct and highly privileged order. Their property is sacred; their persons are inviolable; and while the colour of their turbans, and the revered title of Shereef, announce to the people the august dignity which they bear, they derive from the hereditary nature of their privileges a high degree of permanent influence, and sometimes of dangerous power.[8] Among the privileges of their rank may be numbered an exemption from certain punishments, and that sort of general indulgence which the prevalent dread of shedding the blood of the Prophet unavoidably creates. To these circumstances of distinction it is owing that, like the Nobility of other States, they are sometimes subjected to, and feel a particular apprehension of the penalty of dishonour, especially of that of having dust thrown upon their heads. But great as the privileges of this high order unquestionably are, the individuals who compose it have no union or general concert with each other; for neither in contests for power, nor in resistance to oppression, do they ever act as a body. Some of the class are devoted to the indolence of a religious life; but a larger proportion is engaged in the active concerns and progressive pursuits of commerce: for, in general, the descendants of Mahomet, following the example of their great ancestor, are either Princes or Merchants. The _Revenue_ of Fezzan is composed of a variety of branches, the principal of which are,
