As the title says, with a POD around 1830 or higher, make a scenario where two distinctly different North and South identities emerge, and OTL German Nationalism doesn’t exist in the same form, with different unification efforts taking place in the north and south, and ideally create two separate German states, one with direct control of the North and one in the South.
The best way i could see this happening is a much more conservative Leader German State idea, with Bismarck stopping after the North German Federation was created? Idk, but I would like to see what you guys have in mind.
