Toghon Temür
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 town of Yingchang, the last major city in China proper 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.
