History of Torun

general is known as Kulm law. In 1236, due to frequent flooding, it was relocated to the present site of the Old Town. In 1263 Franciscan monks settled in the city, followed in 1239 by Dominicans. In 1264 the adjacent New Town was founded predominantly to house Torun's growing population of craftsmen and artisans. In 1280, the city (or as it was then, both cities) joined the mercantile Hanseatic League, and thus became an important medieval trade centre.

The First Peace of Thorn ending the Polish–Lithuanian–Teutonic War was signed in the city in February 1411. In 1440, the gentry of Thorn formed the Prussian Confederation, and in 1454 rose with the Confederation against the Monastic state of the Teutonic Knights in the Thirteen Years' War. After almost 200 years, the New and Old Towns amalgamated in 1454. The Poles destroyed the Teutonic castle. The Thirteen Years' War ended in 1466 with the Second Peace of Thorn, in which the Teutonic Order ceded their control over western provinces, henceforth Royal Prussia. Toruń became part of Kingdom of Poland.

In 1557, during the Protestant Reformation, the city adopted Protestantism, while most Polish cities remained Roman Catholic. Under Mayor Heinrich Stroband (1586–1609), the city became centralized. Administrative power passed into the hands of the city council. In 1595 Jesuits arrived to promote the Counter-Reformation, taking control of St. John's Church. The Protestant city officials tried to limit the influx of Catholics into the city, as Catholics (Jesuits and Dominican monks) already controlled most of the churches, leaving only St. Mary's to Protestant citizens.

In 1677 the Prussian historian and educator Christoph Hartknoch was invited to be director of the Thorn Gymnasium, a post which he held until his death in 1687
