In Leipzig, East Germany, the first of weekly demonstration for the legalisation of opposition groups and democratic reforms takes place.

The Monday demonstrations (German: Montagsdemonstrationen in der DDR) were a series of peaceful political protests against the government of the German Democratic Republic (GDR) that took place in towns and cities around the country on various days of the week from 1989 to 1991. The Leipzig demonstrations, which are the most well known, took place on Mondays. The protests are conventionally separated into five cycles.

Leipzig (, German: [ˈlaɪptsɪç ] (listen); Upper Saxon: Leibz'sch) is the most populous city in the German state of Saxony. With a population of 605,407 inhabitants as of 2021 (1.1 million residents in the larger urban zone), it surpasses the Saxon capital of Dresden, and is Germany's eighth most populous city as well as the second most populous city in the area of former East Germany after (East) Berlin. Together with Halle (Saale), the largest city of the neighbouring state of Saxony-Anhalt, the city forms the polycentric Leipzig-Halle Conurbation. Between the two cities (in Schkeuditz) lies Leipzig/Halle Airport.

Leipzig is located about 160 km (100 mi) southwest of Berlin in the Leipzig Bay, which constitutes the southernmost part of the North German Plain, at the confluence of the White Elster River (progression: Saale→ Elbe→ North Sea) and two of its tributaries: the Pleiße and the Parthe. The name of the city as well as the names of many of its boroughs are of Slavic origin.

Leipzig has been a trade city since at least the time of the Holy Roman Empire. The city sits at the intersection of the Via Regia and the Via Imperii, two important medieval trade routes. Leipzig was once one of the major European centres of learning and culture in fields such as music and publishing. After the Second World War and during the period of the German Democratic Republic (East Germany) Leipzig remained a major urban centre in East Germany, but its cultural and economic importance declined. Events in Leipzig in 1989 played a significant role in precipitating the fall of communism in Central and Eastern Europe, mainly through demonstrations starting from St. Nicholas Church. The immediate effects of the reunification of Germany included the collapse of the local economy (which had come to depend on highly polluting heavy industry), severe unemployment, and urban blight. Starting around 2000, however, the decline was first arrested and then reversed and, since then, Leipzig has seen significant changes with the restoration of major historical buildings, the demolition of derelict properties of little historical value, and the development of new industries and a modern transport infrastructure.Leipzig today is an economic centre, is rated as the most livable city in Germany by the GfK marketing research institution, and has the second-best future prospects of all cities in Germany according to the Hamburg Institute of International Economics (HWWI) and Berenberg Bank. The city is one of two seats of the German National Library, as well as the seat of the German Federal Administrative Court. Leipzig Zoo is one of the most modern zoos in Europe and ranks first in Germany and second in Europe. Since the opening of the Leipzig City Tunnel in 2013, Leipzig forms the centrepiece of the S-Bahn Mitteldeutschland public transit system. Leipzig is currently listed as a "Sufficiency" level global city by the Globalization and World Cities Research Network, Germany's "Boomtown" and was the 2019 European City of the Year.Leipzig has long been a major centre for music, both classical as well as modern "dark alternative music" or darkwave genres. The Oper Leipzig is one of the most prominent opera houses in Germany. Leipzig is also home to the University of Music and Theatre "Felix Mendelssohn Bartholdy". The Leipzig Gewandhaus Orchestra, established in 1743, is one of the oldest symphony orchestras in the world. Johann Sebastian Bach is one among many major composers who lived and worked in Leipzig. During a stay in the city, Friedrich Schiller wrote his poem "Ode to Joy".
