I've read some timelines where Germany is united earlier - usually in 1848 at the Frankfurt Assembly, with appropriate butterflies regarding WW1, etc.
Now, my question is whether it would be possible to have a German Unification past its OTL date of 1871. Perhaps the Franco-Prussian War ends in a stalemate with a status quo ante bellum peace, or a Prussian defeat?
Could a unification still happen at a later date, perhaps as late as the early 20th century, or would "Germany" remain a loose collection of squabbling mini-states without the Prussians victory over the French?
