China's Most Mysterious Catastrophe! Beijing Explosion 'Near-Atomic Bomb Level' Kills 20,000, Truth Remains Unknown

During the Tianqi era of the Ming Dynasty, a mysterious and massive explosion in Beijing reduced tens of thousands of homes to rubble and claimed over 20,000 lives. Even the emperor was startled by the sudden blast and took cover under a table. Known as the 'Tianqi Explosion,' this disaster's immense destructive power has made it one of the greatest unsolved mysteries in Chinese history.

How extensive was the explosion's impact?

According to a report by Sohu.com, on May 30, 1626 (the 6th day of the 5th month in the 6th year of Tianqi), at around 9 a.m., the sky over Beijing was clear. Suddenly, a deafening explosion erupted near Wanggongchang, a facility responsible for producing and storing black powder. The ground shook violently, and smoke and dust shot into the sky. Located in the southwestern part of Beijing, Wanggongchang was a key gunpowder manufacturing and storage site managed by the Ministry of Works of the Ming Dynasty, hence the event is also known as the 'Wanggongchang Explosion.'

The explosion's impact was vast, stretching from Shunchengmen Street in the east, to Xingbu Street in the north, and Pingzemen in the west, affecting an area spanning dozens of miles. Countless homes were instantly reduced to ashes, with over 20,000 people killed and countless others injured. The blast was so powerful that bodies, tiles, and various objects were hurled up to 10 li (about 5 km) away, creating a horrifying scene far beyond what a typical fire or gunpowder explosion could cause.

How did Emperor Xizong survive?

At the time of the explosion, Emperor Xizong (Zhu Youxiao) was dining in the Qianqing Palace. The sudden violent tremors caused the palace to shake, and he quickly fled to the Jiaotai Hall, taking shelter under a large table, which saved his life. In the chaos, palace attendants scattered in panic; one close aide was struck by a falling beam and killed instantly, while workers repairing the palace fell from heights and died.

The shockwaves spread rapidly, with reports of collapsed buildings even in Jizhou, hundreds of miles away. To calm public fear, Emperor Xizong issued a 'Zuiji Edict,' taking responsibility for governmental failures, announcing a general amnesty, and allocating funds for disaster relief. Among the public, various theories emerged—some believed it was an earthquake or meteorite impact, while others speculated about alien landings. However, most scholars, considering the explosion's epicenter was a gunpowder depot, widely accept spontaneous ignition of stored gunpowder as the most plausible explanation.

What was the true cause of this massive explosion? Its power rivaled the Hiroshima atomic bomb

Modern research estimates the Tianqi Explosion's force at approximately 10,000 to 20,000 tons of TNT equivalent—on par with the atomic bomb dropped on Hiroshima. However, based on Wanggongchang's black powder production and storage capacity at the time, annual output was at most 3,000 tons, and stockpiles could not have exceeded 10,000 tons.

Even if all stored gunpowder had detonated simultaneously, the resulting destructive power still fails to adequately explain the scale of devastation observed. As a result, the true cause of this disaster remains unexplained, cementing the Tianqi Explosion's status as one of the most mysterious and significant events in Chinese history.
