Only if the French Revolution is more successful, but not enough to incorporate the German States. So mabe the French fund some kind of Socialistic ATL 1848 Revolations. However a successful Jacobin France butterflys Karl Marx.
Even if the french revolution was more successful, it would not have turned into some kind of socialist government.
The biggest chaos France ever faced was the french revolution. Even at the time when the most extremist revolutionaries held power, they did not want any kind of socialist evolution. They even crushed the microscopic minority called the "hebertists" that could be quickly called "pre-socialists".
In 1848, they were very small socialist movements in France. It was impossible to have a socialist revolution in France because had universal suffrage and was a nation of small peasants that hated the distributionists.
This may be hard to understand today because so many french media and teachers promote left-wing ideas. But a very very wide majority of the french wanted to crush the commune of Paris in 1871.
They wanted to crush it because they refused any risk that Paris lead the country into chaos like it had done in the years of the first french revolution.
They wanted to crush it because they rejected what was done in Paris by the commune of Paris.
You just could not have a socialist revolution in 19th century countries that had not reached a level of industrial development that could create the conditions for a big socialist party. You can't have it in a country where rural small property is dominant.
The russian revolution was the exception that proves the rule. It needed the existence of immense aristocratic properties, the personal initiative of Lenin who invented the notion of militarily organized political party, and many specific russian conditions.
Given the military organization of Prussia, any socialist coup attempt would be crushed. And you won't have a socialist majority in Germany in the 19th century.
