University of Wittenberg in the context of "Andreas Karlstadt"

The Ninety-five Theses or Disputation on the Power and Efficacy of Indulgences is a list of propositions for an academic disputation written in 1517 by Martin Luther, then a professor of moral theology at the University of Wittenberg, Germany. The Theses are retrospectively considered to have launched the Protestant Reformation and the birth of Protestantism, despite various quasi- or proto-Protestant groups having existed previously.

The Theses are framed as propositions to be argued in an academic debate rather than necessarily representing Luther's opinions. They aired contemporary theological misgivings about the theory and practice of indulgences and their relation to repentance, penance and papal authority: this was triggered by the scandal of certain Catholic clergy, who were supposedly selling plenary indulgences in Germany, which were certificates supposed to reduce the temporal punishment in purgatory for sins committed by the saved purchasers or their loved ones.

Georg Philipp Friedrich Freiherr von Hardenberg (2 May 1772 – 25 March 1801), pen name Novalis (/noʊˈvɑːlɪs/; German: [noˈvaːlɪs]), was a German aristocrat and polymath, who was a poet, novelist, philosopher and mystic. He is regarded as an influential figure of Jena Romanticism.

Novalis was born into a minor aristocratic family in Electoral Saxony. He was the second of eleven children; his early household observed a strict Pietist faith. He studied law at the University of Jena, the University of Leipzig, and the University of Wittenberg. While at Jena, he published his first poem and befriended the playwright and fellow poet Friedrich Schiller. In Leipzig, he then met Friedrich Schlegel, becoming lifelong friends. Novalis completed his law degree in 1794 at the age of 22. He then worked as a legal assistant in Tennstedt immediately after graduating. There, he met Sophie von Kühn. The following year Novalis and Sophie became secretly engaged. Sophie became severely ill soon after the engagement and died just after her 15th birthday. Sophie's early death had a life-long impact on Novalis and his writing.

Philipp Jakob Spener (23 January 1635 – 5 February 1705) was a German Lutheran theologian who essentially founded what became known as Pietism. He was later dubbed the "Father of Pietism". A prolific writer, his two main works, Pia desideria (1675) and Allgemeine Gottesgelehrtheit (1680), were published while he was the chief pastor in the Lutheran Church at Frankfurt.

In 1691, he was invited to Berlin by the court of Brandenburg. In Berlin, Spener was at odds with the predominant Lutheran orthodoxy, as he had been all his life. Spener influenced the foundation of the University of Halle. Disputing his positions, the theological faculty of Wittenberg, formally accused him of 264 errors.
