acy of the khans of Persia; and he often interposed
his authority, and sometimes his arms, to check their depredations, and
to preserve the peace and balance of his Turkish frontier. The death
of Cazan, [38] one of the greatest and most accomplished princes of the
house of Zingis, removed this salutary control; and the decline of the
Moguls gave a free scope to the rise and progress of the Ottoman Empire.

545, 546) might propagate and color the report of the union and victory
of the kings of the Franks on the confines of Bulgaria. Abulpharagius
(Dynast. p. 310) after forty years, beyond the Tigris, might be easily
deceived.]

the Moguls, since the fabulous defeat of Batou, had not attacked either
the Franks or Greeks; and of this he is a competent witness. Hayton
likewise, the Armenian prince, celebrates their friendship for himself
and his nation.]

[Footnote 38: Pachymer gives a splendid character of Cazan Khan, the
rival of Cyrus and Alexander, (l. xii. c. 1.) In the conclusion of his
history (l. xiii. c. 36) he _hopes_ much from the arrival of 30,000
Tochars, or Tartars, who were ordered by the successor of Cazan to
restrain the Turks of Bithynia, A.D. 1308.]

the critical learning of Mm. De Guignes (Hist. des Huns, tom. iv. p.
329--337) and D'Anville, (Empire Turc, p. 14--22,) two inhabitants of
Paris, from whom the Orientals may learn the history and geography of
their own country. * Note: They may be still more enlightened by the

After the retreat of Zingis, the sultan Gelaleddin of Carizme had
returned from India to the possession and defence of his Persian
kingdoms. In the space of eleven years, than hero fought in person
fourteen battles; and such was his activity, that he led his cavalry in
seventeen days from Teflis to Kerman, a march of a thousand miles.
Yet he was oppressed by the jealousy of the Moslem princes, and the
innumerable armies of the Moguls; and after his last defeat, Gelaleddin
