Red Bull Leipzig, commonly known as RB Leipzig, is a professional football club based in Leipzig, Germany. Founded on May 19, 2009, by the Austrian energy drink company Red Bull GmbH, the team quickly rose through the ranks of German soccer to become one of its top clubs (source).
The formation of RB Leipzig marked Red Bull's first foray into German football. After purchasing the playing rights of fifth-tier side SSV Markranstädt for €350,000 and renaming it RasenBallsport Leipzig e.V., Red Bull aimed to reach Bundesliga within just a few years (source).
In their debut season (2009-10), RB Leipzig secured promotion from Oberliga (fifth tier) to Regionalliga Nordost (fourth tier). The team continued its ascent under coach Alexander Zorniger and achieved another promotion in 2012-13 after finishing first in Regionalliga Nordost (source).
In just five years since its inception, RB Leipzig reached the second tier of German football - 2. Bundesliga - following their successful campaign during the 2013-14 season under manager Ralf Rangnick. That same year saw key player signings like Emil Forsberg and Marcel Sabitzer who would contribute significantly to future successes (source.
