NRW-Liga
The NRW-Liga, or Nordrhein-Westfalen-Liga (English: North Rhine-Westphalia League), was the highest football league in the state of North Rhine-Westphalia from 2008 to 2012. It was one of the eleven Oberliga groups in German football, the fifth tier of the German football league system.
With the reorganisation of the German league system in 2012, the NRW-Liga was disbanded once more as the Regionalliga West above it would then only contain clubs from North Rhine-Westphalia. The league was replaced by the three regional leagues, the Mittelrheinliga, Niederrheinliga and Oberliga Westfalen at this level.
