Through its predecessor, the Bayerische Gemeindebank (founded 1914), and its much older subsidiary, the Bayerische Landesbodenkreditanstalt (founded 1884), BayernLB can claim to have more than 100 years of history. In its current form, the bank was founded by law on June 27, 1972, through the merger of the two institutions. Its first President was CSU veteran politician Karl Theodor Jacob.
