THE EAST IN MEDIEVAL TIMES 301 made large and valuable contributions to civilisation, her political history, as ever, was very much disturbed. Progress in" that vast country has been so often interrupted by war and barbarism that one really wonders how the Chinese could at all produce their rich culture. Under the Han dynasty (206 B.C. to 221 A.D.), in addition to China proper, Tong- krng and Annam had been reduced to being tributary states. Besides developing excellent pottery, jade, bronze and iron- work, silk brocades and embroideries, etc., the Han emperors had encouraged literature and secured its preservation by getting Confucian classics engraved on stone. The invention of paper in 105 A.D. and! the modification of the ancient Chinese characters had made writing an easier art. The in- vention of the hair-pencil under the Ch'in had also facilita- ted the practice of that art on silk. Soothill describes this as 'the period of the first great collators, commentators, and historians, and of the fathers of the form of much subse- quent poetry.' He also writes ; " Whatever may be said of the government, the world-enriching discovery of paper would alone entitle the Han period to be styled glorious." After this China was partitioned between the three king- doms of Wei, Wu, and Shu. These kingdoms fought among themselves (221—589) and paved the way for the Tartar invasions. It was the age, as in Europe, of chaos and chivalry. But out of this darkness one figure arises. It is that of a Tartar who, in 397, founded the House of Toba. He organised the civil administration and, by his encouragement of learning, civilised his barbarous people. Though the Tobas at first persecuted the Buddhists, they became its great supporters later, and through them the religion was finally established in China. Its in- fluence may be illustrated by the attitude of the founder of a succeeding dynasty, viz., the Liang dynasty (502—
