Wang Xuance (Chinese: 王玄策 (pinyin wáng xuáncè), fl. 7th century) was a Tang Dynasty guard officer and diplomat. In 648, Tang Taizong sent him to India in response to Harshavardhana sending an ambassador to China. However once in India he discovered Harshavardhana had died and the new king attacked Wang and his 30 mounted subordinates. This led to Wang Xuance escaping to Tibet and then mounting a joint of over 7,000 Nepalesemounted infantry and 1,200 Tibetaninfantry and attack on the Indian state on June 16. The success of this attack won Xuance the prestigious title of the "Grand Master for the Closing Court." He also secured a reported Buddhist relic for China.
