The story of Tibet King Songtsan Gambo and Princess Wencheng of Tang Dynasty is well known by Tibetan people as well as Han people. If you wanna know Tibet, you must know this story at first as there are many tourist sites related with this story.
The story happened about 1300 years ago when Princess Wencheng of the Tang Dynasty (618-907) left Chang’an (Xi’an) to marry Songtsan Gambo, king of the Tubo kingdom. Their marriage was aimed to maintain amicable relations between the Tang and the Tubo.
The Tang was a powerful dynasty in Chinese history. It was the civilization center of East Asia. Neighboring nations and tribes fell under the influence of the Tang Dynasty, and earnestly sought ties with the dynasty. They either claimed allegiance to the Tang or paid tributes to the imperial court. This stimulated exchanges between the Han and other nationalities.
The same period saw Songtsan Gambo gain control of the highland area in the west. After having annexed some tiny states, he founded the Tubo Kingdom and named Loso (Lhasa) the capital city. Beginning in 634, he twice dispatched Gar Tongtsan to Chang’an,
where the Tubo minister informed the Tang of Songtsan Gambo’s desire for a daughter of the Tang emperor. Tang Emperor Taizong agreed to let Wencheng marry the Tubo king. Accompanied by the Tubo minister, Princess Wencheng set out for the farway Tubo Kingdom. This segment of history was later turned into tales which remain an important part of Tibetan folklore.
