The correct response is: It was a plague that travelled along the Silk Road and devastated communities and economies.
The Black Death, which occurred in the 14th century, specifically from 1347 to 1351, was caused by the bacterium Yersinia pestis and resulted in the deaths of an estimated 25 to 30 million people in Europe, which was about one-third of the population at the time. It significantly impacted communities by leading to severe labor shortages, social upheaval, and economic decline in many areas. The plague also altered social structures and relations, contributing to shifts in power dynamics, particularly between the working class and landowners. Additionally, the trauma and loss spurred changes in religious beliefs and practices, with a rise in fervent religious movements and changes in art and culture.
