Leipzig is the most populous city in the German state of Saxony. With a population of 605,407 inhabitants as of 2021, it is Germany's eighth most populous city as well as the second most populous city in the area of former East Germany after Berlin. Together with Halle, the largest city of the neighbouring state of Saxony-Anhalt, the city forms the polycentric conurbation of Leipzig-Halle. Between the two cities lies Leipzig/Halle Airport.
Leipzig is located about 160 kilometres 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 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.
