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, was one of the deadliest pandemics in human history, caused by the bacterium Yersinia pestis. It spread from Asia to Europe primarily through trade routes like the Silk Road and resulted in significant mortality, wiping out an estimated 25-30 million people in Europe—about a third of the continent's population at the time. The impact was profound, leading to social, economic, and cultural changes, including labor shortages that contributed to the decline of feudalism, shifts in power dynamics, and changes in attitudes towards religion and science.
