Not directly about the bank, but [Insurgent Democracy](https://press.uchicago.edu/ucp/books/book/chicago/I/bo210283...) is a great read. The Non-Partisan League successfully organized rural farmers against corporate power in the 1910s & 20s. Though they only were in power for a decade or so, their legacy is still quite strong. BND, state hail insurance, and a state-run grain mill to name a few!
