fever of conquest such as possessed Europe when the New World and the route to the East round the Cape were discovered. India's expansion was slow, generally peaceful and attracted little attention at home. Partly it was due to the natural permeation and infiltration of a superior culture beyond its own borders, but it is equally natural that this gradual process should have been sometimes accelerated by force of arms. The Hindus produced no Tamerlanes or Babers, but a series of expeditions, spread over long ages, but still not few in number, carried them to such distant goals as Ceylon, Java and Camboja.

But the diffusion of Indian influence, especially in China, was also due to another agency, namely religious propaganda and the deliberate despatch of missions. These missions seem to have been exclusively Buddhist for wherever we find records of Hinduism outside India, for instance in Java and Camboja, the presence of Hindu conquerors or colonists is also recorded.[2] Hinduism accompanied Hindus and sometimes spread round their settlements, but it never attempted to convert distant and alien lands. But the Buddhists had from the beginning the true evangelistic temper: they preached to all the world and in singleness of purpose: they had no political support from India. Many as were the charges brought against them by hostile Confucians, it was never suggested that they sought political or commercial privileges for their native land. It was this simple disinterested attitude which enabled Buddhism, though in many ways antipathetic to the Far East, to win its confidence.

Ceylon is the first place where we have a record of the introduction of Indian civilization and its entry there illustrates all the phenomena mentioned above, infiltration, colonization and propaganda. The island is close to the continent and communication with the Tamil country easy, but though there has long been a large Tamil population with its own language, religion and temples, the fundamental civilization is not Tamil. A Hindu called Vijaya who apparently started from the region of Broach about 500 B.C. led an expedition to Ceylon and introduced a western Hindu language. Intercourse with the north was doubtless maintained, for in the reign of Asoka we find the King of Ceylon making overtures to him and receiving with enthusiasm the missionaries whom he sent. It is possible that southern India played a greater part in this conversion than the accepted legend indicates, for we hear of a monastery built by Mahinda near Tanjore.[3] But still language, monuments and tradition attest the reality of the connection with northern India.

It is in Asoka's reign too that we first hear of Indian influence spreading northwards. His Empire included Nepal and Kashmir, he sent missionaries to the region of Himavanta, meaning apparently the southern slopes of the Himalayas, and to the Kambojas, an ambiguous race who were perhaps the inhabitants of Tibet or its border lands. The Hindu Kush seems to have been the limit of his dominions but tradition ascribes to this period the joint colonization of Khotan from India and China.

Sinhalese and Burmese traditions also credit him with the despatch of missionaries who converted Suvarṇabhûmi or Pegu. No mention of this has been found in his own inscriptions, and European critics have treated it with not unnatural scepticism for there is little indication that Asoka paid much attention to the eastern frontiers of his Empire. Still I think the question should be regarded as being sub judice rather than as answered in the negative.

Indian expeditions to the East probably commenced, if not in the reign of Asoka, at least before our era. The Chinese Annals[4] state that Indian Embassies reached China by sea about 50 B.C. and the Questions of Milinda allude to trade by this route: the Ramayana mentions Java and an inscription seems to testify that a Hindu king was reigning in Champa (Annam) about 150 A.D. These dates are not so precise as one could wish, but if there was a Hindu kingdom in that distant region in the second century it was probably preceded by settlements in nearer halting places, such as the Isthmus of Kra[5] or Java, at a considerably anterior date, although the inscriptions discovered there are not earlier than the fifth century A.D.

Java seems to have left some trace in Indian tradition, for instance the proverb that those who go to Java do not come back, and it may have been an early distributing centre for men and merchandize in those seas. But Ligor probably marks a still earlier halting place. It is on the same coast as the Mon kingdom of Thaton, which had connection with Conjevaram by sea and was a centre of Pali Buddhism. At any rate there was a movement of conquest and colonization in these regions which brought with it Hinduism and Mahayanism, and established Hindu kingdoms in Java, Camboja, Champa and Borneo, and another movement of Hinayanist propaganda, apparently earlier, but of which we know less.[6] Though these expeditions both secular and religious probably took ship on the east coast of India, e.g. at Masulipatam or the Seven Pagodas, yet their original starting point may have been in the west, such as the district of Badami or even Gujarat, for there were trade routes across the Indian Peninsula at an early date.[7]

It is curious that the early history of Burma should be so obscure and in order not to repeat details and hypotheses I refer the reader to the chapter dealing specially with this country. From an early epoch Upper Burma had connection with China and Bengal by land and Lower Burma with Orissa and Conjevaram by sea. We know too that Pali Buddhism existed there in the sixth century, that it gained greatly in power in the reign of Anawrata (c. 1060) and that in subsequent centuries there was a close ecclesiastical connection with Ceylon.

Siam as a kingdom is relatively modern but like Burma it has been subject to several influences. The Siamese probably brought some form of Buddhism with them when they descended from the north to their present territories. From the Cambojans, their neighbours and at one time their suzerains, they must have acquired some Hinduism and Mahayanism, but they ended by adopting Hinayanism. The source was probably Pegu but learned men from Ligor were also welcomed and the ecclesiastical pre-eminence of Ceylon was accepted.

We thus see how Indian influence conquered Further India and the Malay Archipelago and we must now trace its flow across Central Asia to China and Japan, as well as the separate and later stream which irrigated Tibet and Mongolia.

Tradition as mentioned ascribes to Asoka some connection with Khotan and it is probable that by the beginning of our era the lands of the Oxus and Tarim had
