[Why] The last Shang king Zhou was depraved and brutal, plundering at home and overstretching abroad, having lost the hearts of the people. Risen in the west under King Ji Fa, the Zhou tribe resolved to launch a punitive war on behalf of the suffering populace. [What] King Wu of Zhou allied with many eastern lords and met the massive Shang defenders at Muye for the life-or-death battle. Large numbers of Shang slaves defected on the field, and King Zhou, seeing all was lost, climbed his terrace and self-immolated. [Who] King Wu of Zhou was an outstanding military leader who aligned with the will of heaven and the people, commanding with composure. His strategist Jiang Shang (Lord Taigong) provided the decisive plan that shattered the Shang line. [How] The battle directly overthrew the cruel Shang and laid the founding cornerstone of the Western Zhou. It is the largest and most tragic regime-toppling decisive battle of the Bronze Age in Chinese history.
