In the 16th century Augsburg became one of Germany's largest cities. Augsburg was a major manufacturing center for textiles, armor, scientific instruments, as well as gold- and silver-smithing. The prolific printers of Augsburg also made the city the largest producer of German-language books in the Holy Roman Empire. Like other free imperial cities, Augsburg was an independent entity, and had authority over its tax policies. Augsburg's wealth attracted artists seeking patrons. The city rapidly became a creative centre for sculptors and musicians. Augsburg became the base of the Holbein family, starting with Hans Holbein the Elder. The composer Leopold Mozart was born and educated in Augsburg. Rococo became so prevalent that it became known as "Augsburg style" throughout Germany. Augsburg benefitted majorly from the establishment and expansion of the Kaiserliche Reichspost in the late 15th and early 16th century. This postal system, which was the first modern postal service in the world, was created through negotiations and agreements between the Taxis family represented by and the early Habsburgs monarches, notably Maximilian I, his son Philip the Handsome and grandson Charles V. Even when the Habsburg empire began to extend to other parts of Europe, Maximilian's loyalty to Augsburg, where he conducted a lot of his endeavours, meant that the imperial city became "the dominant centre of early capitalism" of the sixteenth century, and "the location of the most important post office within the Holy Roman Empire". From Maximilian's time, as the "terminuses of the first transcontinental post lines" began to shift from Innsbruck to Venice and from Brussels to Antwerpt, in these cities, the communication system and the news market started to converge. As the Fuggers as well as other trading companies based their most important branches in these cities, these traders gained access to these systems as well.(Despite a widely circulated theory which holds that the Fuggers themselves operated their own communication system, in reality they relied upon the imperial posts, presumably from the 1490s onwards, as official members of the court of Maximilian I). Witch hunts Several witch hunts occurred in Augsburg in the late 16th century. Following the 1585–1588 plague epidemic, southeast Germany was shattered by the 1589–1591 witch hunts. Following the 1592–1593 plague epidemic, cities in southeast Germany entered a period of inflation, marked by brutal witch hunts in urban areas. Thirty Years' War Religious peace in the city was largely maintained despite increasing tensions up
