Map - Martin Luther University of Halle-Wittenberg (Martin-Luther-Universität Halle-Wittenberg)

Martin Luther University of Halle-Wittenberg (Martin-Luther-Universität Halle-Wittenberg), also referred to as MLU, is a public, research-oriented university in the cities of Halle and Wittenberg, and is the largest and oldest university in the German state of Saxony-Anhalt. MLU offers German and international (English) courses leading to academic degrees such as BA, BSc, MA, MSc, doctoral degrees, and Habilitation.

The university was created in 1817 through the merger of the University of Wittenberg (founded in 1502) and the University of Halle (founded in 1694). MLU is named after Protestant reformer Martin Luther, who was a professor in Wittenberg. Today, the university campus is located in Halle, while Leucorea Foundation in Wittenberg serves as MLU's convention centre. Both Halle and Wittenberg are about one hour from Berlin via the Berlin–Halle railway, which offers Intercity-Express (ICE) trains.

University of Wittenberg (Universität Wittenberg) was founded in 1502 by Frederick the Wise, Elector of Saxony, as the Renaissance was becoming more and more popular. The foundation of the university was heavily criticized, especially when Martin Luther's Ninety-five Theses reached Albert of Brandenburg, the Archbishop of Mainz. Ecclesiastically speaking, the Electorate of Saxony was subordinate to Albert. He criticized the elector for Luther's theses, viewing the recently founded university as a breeding ground for heretical ideas. Under the influence of Philipp Melanchthon, building on the works of Martin Luther, the university became a centre of Protestant Reformation, even incorporating, at one point in time, Luther's house in Wittenberg, the Lutherhaus, as part of the campus. Notable alumni include George Müller, Georg Joachim Rheticus and – in fiction – William Shakespeare's Prince Hamlet and Horatio and Christopher Marlowe's Doctor Faustus.

University of Halle (Universität Halle) was founded in 1694 by Frederick III, Elector of Brandenburg, who became Frederick I, King in Prussia, in 1701.

In the late 17th century and early 18th century, Halle became a centre for Pietism within Prussia.

In the 17th and 18th centuries, the universities were centers of the German Enlightenment. Christian Wolff was an important proponent of rationalism. He influenced many German scholars, such as Immanuel Kant. Christian Thomasius was at the same time the first philosopher in Germany to hold his lectures not in Latin, but German. He contributed to a rational programme in philosophy but also tried to establish a more common-sense point of view, which was aimed against the unquestioned superiority of aristocracy and theology.

The institutionalisation of the local language (German) as the language of instruction, the prioritisation of rationalism over religious orthodoxy, new modes of teaching, and the ceding of control over their work to the professors themselves, were among various innovations which characterised the University of Halle, and have led to its being referred to as the first "modern" university, whose liberalism was adopted by the University of Göttingen about a generation later, and subsequently by other German and then most North American universities.

The University of Wittenberg was closed in 1813 during the Napoleonic Wars. The town of Wittenberg was granted to Prussia in the Congress of Vienna in 1815, and the university was then merged with the Prussian University of Halle in 1817. It took its present name on 10 November 1933.
