The Leipzig History had several remarkable spots. First mention of this city was in the year 1015, and it received city rights in 1165. It fundamentally gave shape to Saxony and the German history in general.
The city became famous for commerce. Its trade fair, which began in the middle Ages, is the oldest remaining trade fair in the world.
In 1409, the University of Leipzig was founded and the city became the center of German law and the publishing industry.
The first German long distance rail project was between Leipzig and Dresden in 1839. Thus, it became hub of central European rail route traffic and had the largest terminal station by area in Europe. (Their main station (Hauptbahnhof) is huuuuge and incredibly beautiful!)
The city was heavily damaged in World War II but was reestablished after the war to become one of the major cities of East Germany.
And in 1889, it played a major role in the peaceful change to the reunification of Germany.
