Which disease was appropriately named after the dark splotches it formed on its victims' bodies in the 14th century?

In the mid-14th century, a terrifying pandemic swept across continents, leaving a trail of devastation and a distinctive physical mark on its victims. Those afflicted often developed purplish-black lesions and necrosis, particularly on their extremities like fingers, toes, and nose. These unsightly, dark discolorations were a grim indicator of the disease's progression, a visible sign of the internal ravages it inflicted. It was these very symptoms, these dark splotches, that gave the disease its enduring and morbidly appropriate name.

This catastrophic illness is most famously known as the Black Death, though it is also scientifically identified as bubonic plague. Originating in Asia, it traveled westward along trade routes, reaching Europe in the 1340s. Its rapid spread and extremely high mortality rate—estimated to have wiped out 30-60% of Europe's population—made it one of the deadliest pandemics in human history. The disease is caused by the bacterium Yersinia pestis, typically transmitted to humans through the bite of infected fleas carried by rodents. The "bubonic" aspect of its name refers to the painful, swollen lymph nodes that were another hallmark symptom.
