The Black Death, caused by the bubonic plague bacterium Yersinia pestis, was one of the deadliest pandemics in human history, claiming an estimated 75 to 200 million lives in the 14th century. This review provides an overview of the disease's etiology, epidemiology, and impact on European society. We examine the pandemic's spread, symptoms, and mortality rates, as well as the social, economic, and cultural consequences of the disaster. We also discuss the scientific understanding of the plague at the time, the various theories about its origin, and the responses of medieval societies to the crisis. This review aims to provide a comprehensive understanding of the Black Death's significance in human history and its continued relevance to contemporary public health issues.
