[Why] After the establishment of Zhu Wen's Later Liang, it and the northern Shatuo military bloc Later Tang waged decades of bloody contention for hegemony. The two sides fought multiple rounds of extremely brutal tug-of-war for control of the Central Plains central axis. [What] Later Tang Emperor Zhuangzong Li Cunxu, leading elite Shatuo cavalry, launched a hundred-li lightning strike, driving deep to break Kaifeng. The last emperor of Later Liang committed suicide, and the Later Liang regime was announced to vanish in smoke. [Who] Li Cunxu was a Shatuo military genius adept at tactical assault, of unmatched battlefield record but careless in domestic governance, who founded the Later Tang. The last emperor of Later Liang was a passive-defending sovereign with no power to turn things around. [How] The Later Tang's destruction of Liang displayed the apex of the military vitality of northern Shatuo cavalry forces during the Five Dynasties, successfully recovering the Yellow River basin. It temporarily stabilized northern defense but failed to fully end the fragmentation.

The historic event of Conquest of Later Liang by Later Tang represents a key developmental peak of the Huaxia dynastic system. The military peak of the Shatuo group during the turbulent Five Dynasties. By establishing this moral or administrative benchmark, it continues to shape the structural and philosophical fabric of ancient Chinese statecraft.
