King Amshuverma Thakura was the Licchavi king of Nepal in the sixth century AD (605-629 AD) of the Thakuri dynasty. He was learned, bold and farsighted Thakuri emperor of Lichhavi period, he was also a lover of art, architecture and literature. He built Kailash Bhawan. He was a brave king, fought many battles and extended the territory of his kingdom far and wide. A close relationship between Nepal and Tibet was established. He is credited with opening trade routes to Tibet, though he is most famous for one of his daughters, Bhrikuti, who married a Tibetan ruler named Tsrong-tsong Gompo (King Srong Tsangampo / Srong btsan sGampo). She was instrumental in spreading Buddhism to Tibet. The Chinese Buddhist monk Xuanzang, who visited India during the 7th century, described Aṃshuvarmā as a man of many talents.Buddhism was introduced to Tibet and Nepali pagoda structure became popular in Tibet. Then, Nepali art and architecture spread over the countries like China and Japan. An inscription by Aṃshuvarmā dated to 607 at Tistung professes the importance of the "Aryan code of conduct" (i.e. the caste system). A great feat of architecture and engineering, the Kailashkut Bhawan, a grand palace whose remains are found near Hadigaun in Kathmandu, is said to have been built by this ruler.
Amshuverma also married his sister Bhoga Devi to an Indian king, Sur Sen, and this marriage helped him strengthen relationship with India. He maintained the independence and sovereignty of Nepal by his successful foreign policy. His Sanskrit grammar, entitled Shabda Vidya, made him popular even outside the nation. The famous Chinese traveller Huen Tsang praised him in his travel account. Amshuverma's regime became a boon to the Licchavi Period so that it came to be called a golden age. He has become immortal in the history of Nepal.
Amshuverma was endowed with all the kingly qualities and virtues. He was a just, impartial and an able administrator. He was a true servant of the people without any political bias. According to some inscriptions, King Shiva Deva used to say that Amshuverma was a man of universal fame and he always destroyed his enemies by his heroic nature. Some other inscriptions tell us that he had a great personality, who dispelled darkness by the light of his glory. Huen Tsang, himself a learned man and respected scholar, writes about him as a man of high accomplishments and great glory. Amshuverma had written a book on grammar in Sanskrit. The great grammarian Chandraverma, a scholar of Nalanda University, was patronized by him. He followed Shaivism but was tolerant towards all other religions. He can rightly be compared with the Emperor Asoka of India as regards his political outlook and impartial feelings without any religious prejudices. For the development of economic condition of the people he paid great attention to the improvement of trade and commerce of the country. Nepal had trade relations with India, Tibet and China and became the thoroughfare of India's trade with China and vice versa. Amshuverma gave equal importance to industrial advancement and agricultural prosperity. He made every effort to help the people by providing canals to irrigate the fields. He levied a water tax, a land tax, a defense tax and a luxury tax, using the income from these sources for the development works of the country and not for his personal pleasure and luxury.
