context_page_description: The Mongol invasions of Vietnam or Mongol-Vietnamese Wars refer to the military campaigns launched by the Mongol Empire, and later the Yuan dynasty, against the Trần dynasty in Đại Việt and the Champa in 1258, 1282–1284, 1285, and 1287–88. In studies of China and Mongolia, the campaigns are often treated as a success due to the establishment of tributary relations with Dai Viet despite the Mongols suffering several military defeats. In contrast, Vietnamese historiography emphasizes the Dai Viet military victories.
  The first invasion began in 1258 under the united Mongol Empire, as it looked for alternative paths to invade Song China. The Mongol general Uriyangkhadai was successful in capturing the Dai Viet capital Thang Long before turning north in 1259 to invade the Song dynasty in modern-day Guangxi as part of a coordinated Mongol attack with armies attacking in Sichuan under Möngke Khan and other Mongol armies attacking in modern-day Shandong and Henan. The first invasion also established tributary relations between the Trần dynasty, formerly a Song dynasty tributary state, and the Yuan dynasty.
