What does leftist mean in this context? Sure you could say the "nationalist" movements against monarchies and for more democratic processes were progressive at the time, i.e. they wanted to change the status quo. Calling them leftist in the modern sense (again with a huge caveat about what leftist even mean), doesn't make much sense IMO. Also it's important not to forget that the internationalist movements (which I'd argue fit modern definitions of "left" much more closely) developed quite quickly (in historical timeframes) after, e.g. it was only 50 odd years between the Warburg festival in Germany (generally considered the birth of German nationalism) and the Paris commune.
