In July of 1518, 400 people of the city of Strasbourg, France spontaneously started dancing for one month. Dancing Plague of 1518 is one of the most bizarre incidents you’ll ever read about.
It started with only one woman. Frau Troffea. It eventually grew to around 400 people who danced without rest in the morning, mid-day, afternoon, dusk, and night. The leaders of Strasbourg soon noticed and declared that the cause was ‘hot blood’. Their solution? MORE dancing. The authorities believed that more dancing would get the ‘boogie’ out of their systems. Musicians were hired and even a wooden stage was built for the dancers.
After a month had passed, the dancers stopped and went back to their regular lives (except for those who died from heart attacks and exhaustion). The cause of this dancing plague is still unknown.
