Yingchang
Yingchang () was one of the important cities in the Yuan dynasty. It was situated on Lake Taal Nor in modern Heshigten Banner, Inner Mongolia. The city of Yingchang was built by the Khongirad Mongols in 1271, the same year that Kublai Khan established the Yuan dynasty. The city was the administrative seat of the Prince of Lu (鲁王). This square-walled city incorporated Chinese-like symmetry, wide axial streets from the gates led to an administrative compound in the center north area, emulating the Tang style. Shortly after Toghon Temür, the last Yuan emperor, lost Dadu and Shangdu to  the Ming dynasty in 1368 and 1369 respectively, the Yuan remnants (now referred to as the Northern Yuan) established their capital at Yingchang. After the death of Toghon Temür in this city in 1370, the Ming armies managed to capture the Yingchang, one of the major cities still in the hands of the Northern Yuan, in the same year. Biligtü Khan Ayushiridara fled north soon afterwards and later made Karakorum the capital city. The Northern Yuan once took back Yingchang in 1374, but the Ming recaptured the city in 1380.
