Description Droughts and heatwaves are both dangerous natural hazards with a potential significant impact on human societies. In order to understand these hazards, it is important to examine such extreme events in the past. During the years 1471 to 1474, warm and dry weather conditions are described in most parts of Europe. Until now, these extraordinary years have not been examined in depth. Moreover, in spring 1473, a great drought and heat occurred in Europe. This heatwave facilitated a fast phenological development. During the summer and the autumn, temperatures were unusually high, and extremely dry weather conditions continued. In many places, the harvest began remarkably early, and there was abundant wine of a good quality. Fruit trees even bloomed for the second time in autumn. The heat and drought had a considerable impact on the environment and also caused damage to agriculture and society, including water shortages, harvest failures and rising food prices. The weather conditions of the years from 1471 to 1474 were outstanding during the fifteenth century and the heatwave and drought, as well as impacts on environment, economy, and society in the year 1473, were comparable to—if not more severe—than those in the year 1540. Learning from past climate anomalies like the 1473 drought in Europe is important for evaluating more recent and future climate extremes under increasing anthropogenic pressure.
