The Thirty Years' War (1618–1648) was fought primarily in what is now Germany, and at various points involved most countries in Europe. It was one of the longest and most destructive conflicts in European history. The conflict lasted, unceasing, for 30 years, making it one of the longest continuous wars in modern history.

The origins of the conflict and goals of the participants were complex, and no single cause can accurately be described as the main reason for the fighting. Initially, the war was fought largely as a religious conflict between Protestants and Catholics in the Holy Roman Empire, although disputes over the internal politics and balance of power within the Empire played a significant part. Gradually, the war developed into a more general conflict involving most of the European powers. In this general phase, the war became more a continuation of the Bourbon–Habsburg rivalry for European political pre-eminence, and in turn led to further warfare between France and the Habsburg powers, and less specifically about religion.

Various wars have been named after their approximate duration:

Johann Christoph Friedrich von Schiller [ˈjoːhan ˈkʁɪstɔf ˈfʁiːdʁɪç fɔn ˈʃɪlɐ] (10 November 1759 – 9 May 1805) was a German poet, philosopher, historian, and playwright. During the last seventeen years of his life (1788–1805), Schiller struck up a productive, if complicated, friendship with already famous and influential Johann Wolfgang von Goethe. They frequently discussed issues concerning aesthetics, and Schiller encouraged Goethe to finish works he left as sketches. This relationship and these discussions led to a period now referred to as Weimar Classicism. They also worked together on Xenien, a collection of short satirical poems in which both Schiller and Goethe challenge opponents to their philosophical vision.

Friedrich Schiller was born on 10 November 1759, in Marbach, Württemberg as the only son of military doctor Johann Kaspar Schiller (1733–96), and Elisabeth Dorothea Kodweiß (1732–1802). They also had five daughters. His father was away in the Seven Years' War when Friedrich was born. He was named after king Frederick the Great, but he was called Fritz by nearly everyone. Kaspar Schiller was rarely home during the war, but he did manage to visit the family once in a while. His wife and children also visited him occasionally wherever he happened to be stationed. When the war ended in 1763, Schiller's father became a recruiting officer and was stationed in Schwäbisch Gmünd. The family moved with him. Due to the high cost of living—especially the rent—the family moved to nearby Lorch.
