Chapter LVII: The Turks.
Part III.
The greatness and unity of the Turkish empire expired in the person of Malek Shah. His vacant throne was disputed by his brother and his four sons; ^! and, after a series of civil wars, the treaty which reconciled the surviving candidates confirmed a lasting separation in the Persian dynasty, the eldest and principal branch of the house of Seljuk. The three younger dynasties were those of Kerman, of Syria, and of Roum: the first of these commanded an extensive, though obscure, ^47 dominion on the shores of the Indian Ocean: ^48 the second expelled the Arabian princes of Aleppo and Damascus; and the third, our peculiar care, invaded the Roman provinces of Asia Minor. The generous policy of Malek contributed to their elevation: he allowed the princes of his blood, even those whom he had vanquished in the field, to seek new kingdoms worthy of their ambition; nor was he displeased that they should draw away the more ardent spirits, who might have disturbed the tranquillity of his reign. As the supreme head of his family and nation, the great sultan of Persia commanded the obedience and tribute of his royal brethren: the thrones of Kerman and Nice, of Aleppo and Damascus; the Atabeks, and emirs of Syria and Mesopotamia, erected their standards under the shadow of his sceptre: ^49 and the hordes of Turkmans overspread the plains of the Western Asia.
After the death of Malek, the bands of union and subordination were relaxed and finally dissolved: the indulgence of the house of Seljuk invested their slaves with the inheritance of kingdoms; and, in the Oriental style, a crowd of princes arose from the dust of their feet. ^50
