Landesbank der Rheinprovinz

The Landesbank der Rheinprovinz or Rheinische Landesbank was a German provincial public bank or Landesbank, whose origins go back to the Rheinische Provinzial-Hülfskasse (lit. 'Assistance Fund of the Rhine Province') established 1854 in the Rhine Province of Prussia. Following uncontrolled expansion in the 1920s, it collapsed in 1931, shortly after Austria's Creditanstalt and before Danatbank, thus contributing materially to the European banking crisis of 1931.

The Landesbank der Rheinprovinz was a direct predecessor entity of Westdeutsche Landesbank (WestLB), which had its head office in Düsseldorf on the same grounds where the Rheinische Landesbank had been established. WestLB in turn collapsed in 2007–2008 after uncontrolled balance sheet expansion, in an echo of the previous episode of 1931.
