Under some of this dynasty, Central Asia was comparatively a civilized country; and Christian travellers passed with safety from the banks of the Euphrates to Samarcand and Pekin.

Some of the Chinese emperors favored Christianity, and ordered the erection of numerous churches.
Meanwhile the sword of Moslem fanaticism was advancing eastward.
Bagdad fell before it, and all the country on the Euphrates; then Persia, then Cabul, and the regions of the north.

The Nestorian Church being thus crushed at home, its missions languished.

And finally, about the year 1400, Tamerlane, who has been called 'the greatest of conquerors,' swept like a whirlwind over the remains of Nestorian Christianity, prostrating everything in his course."1 1 Tracey's _History_, p.312.See also _Missionary Herald_ for 1838, pp.
