Ghiyath al-Din Tughluq vs Wang Shichong

Ghiyath al-Din Tughluq, then governor of Dipalpur, led a revolt against the Khilji sultan Khusrau Khan. He defeated Khusrau Khan at the Battle of Saraswati and captured Delhi, proclaiming himself sultan. This established the Tughluq dynasty.

Ghiyath al-Din Tughluq founded the city of Tughlaqabad near Delhi and built a massive fort there. The fort was designed to be impregnable, with thick walls and a strategic location. It served as his capital and a symbol of his power.

Ghiyath al-Din Tughluq led a campaign against the Kakatiya kingdom of Warangal. He defeated the Kakatiya ruler Prataparudra II and annexed the region to the Delhi Sultanate. This extended Tughluq control into the Deccan.

Ghiyath al-Din Tughluq was killed when a wooden pavilion collapsed on him during a victory parade near Tughlaqabad. The structure was reportedly built hastily. His son Muhammad bin Tughluq succeeded him amid suspicions of foul play.

Wang Shichong, a Sui general, staged a coup in Luoyang, killing the Sui regent and declaring himself emperor of the short-lived Zheng dynasty. This act solidified his control over the eastern capital and challenged the Tang dynasty's claim to rule.

Wang Shichong's forces were decisively defeated by Li Shimin's Tang army at Hulao Pass. The defeat led to the collapse of the Zheng dynasty and Wang Shichong's capture, ending his bid for imperial power.

After his capture at Hulao, Wang Shichong was executed by the Tang dynasty. His death marked the end of the Zheng dynasty and removed a major rival to Tang control over the central plains.
