The Black Death was the deadliest pandemic recorded in human history. The Black Death pandemic resulted in the deaths of up to 75–200 million people in Eurasia and North Africa, peaking in Europe from 1347 to 1351. Plague, the disease, was caused by the bacterium Yersinia pestis. The Y. pestis infection most commonly results in bubonic plague, but can also cause septicaemic or pneumonic plagues.

The Black Death was present in the Holy Roman Empire between 1348 and 1351.

The Black Death in medieval culture includes the effect of the Black Death (1347–1350) on art and literature throughout the generation that experienced it.

The consequences of the Black Death have had both immediate and long-term effects on human population across the world. These include a series of biological, social, economic, political and religious upheavals which had profound effects on the course of world history, especially the History of Europe. Often simply referred to as "The Plague", the Black Death was one of the most devastating pandemics in human history, peaking in Europe between 1348 and 1350 with an estimated one-third of the continent's population ultimately succumbing to the disease. Historians estimate that it reduced the total world population from 475 million to between 350 and 375 million. In most parts of Europe, it took nearly 80 years for population sizes to recover, and in some areas more than 150 years.

The Cronaca fiorentina di Marchionne di Coppo Stefani written by Baldassarre Bonaiuti is considered today as one of the best works written on the Black Death in Florence in the year 1348. It is the only known literary work by Bonaiuti. It was written in vulgar Latin. There is no information as to when he may have started his work, but he devoted much time on it in his retirement from about 1378 until his death, a period of seven years.

The crucifix of San Marcello is a medieval work of religious art that is venerated in the Oratory of Santissimo Crocifisso of the Church of San Marcello al Corso in Rome. Having survived a fire that destroyed the church in 1519, the crucifix was popularly believed to possess intercessory powers. During an epidemic of plague in 1522 the crucifix was carried in a procession through the city. According to popular belief at the time, the procession caused the plague to leave the neighborhoods through which the crucifix passed, and eventually to die out in Rome.

The Kingdom of France had the largest population of Europe at the time, and the Black Death was a major catastrophe. The Black Death in France was described by eyewitnesses such as Louis Heyligen, Jean de Venette and Gilles Li Muisis. The Black Death migrated from Southern France to Spain, from Eastern France to the Holy Roman Empire, and to England by ship from Gascony.

Yersinia pestis is a gram-negative, non-motile, rod-shaped, coccobacillus bacterium, without spores. It is a facultative anaerobic organism that can infect humans via the Oriental rat flea. It causes the disease plague, which takes three main forms: pneumonic, septicemic, and bubonic. There may be evidence suggesting Y. pestis originated in Europe in the Cucuteni–Trypillia culture and not in Asia as is more commonly believed.
