Tumult of Thorn: Religious unrest is followed by the execution of nine Protestant citizens and the mayor of Thorn (Toruń) by Polish authorities.

The Tumult of Thorn (Toruń), or Blood-Bath of Thorn refers to executions ordered in 1724 by the Polish supreme court under Augustus II the Strong of Saxony. During a religious conflict between Protestant townsfolk represented by mayor Johann Gottfried Rösner, and the Roman Catholic students of the Jesuit college in the city of Thorn (Toruń) in Royal Prussia, the college had been vandalised by a crowd of German Protestants. The mayor and nine other Lutheran officials were blamed for neglect of duty, sentenced to death, and executed on 7 December 1724.

Protestantism is a branch of Christianity that emphasizes justification of sinners through faith alone, the teaching that salvation comes by unmerited divine grace, the priesthood of all believers, and the Bible as the sole infallible source of authority for Christian faith and practice. The five solae summarize the basic theological beliefs of mainstream Protestantism.

Toruń is a city on the Vistula River in north-central Poland and a UNESCO World Heritage Site. Its population was 196,935 as of December 2021. Previously, it was the capital of the Toruń Voivodeship (1975–1998) and the Pomeranian Voivodeship (1921–1945). Since 1999, Toruń has been a seat of the local government of the Kuyavian-Pomeranian Voivodeship and is one of its two capitals, together with Bydgoszcz. The cities and neighboring counties form the Bydgoszcz–Toruń twin city metropolitan area.
