My understanding of Finnish history is rough but from what I understand Finland was also industrialized in late 1800s as Russian Dutchy under Alexander II's reforms. IIRC reward for being loyal unlike uprising in crimea and poland. It got the benefits of empire. Granted much slower than rest of Europe due to geography. Civil war over russification not unlike purges in SKorean or Taiwan/ROC, at the end of the day you need get the population in line under a national identity either through ideology or coercsion so they can focus on development instead of be distracted by sectarian drama.
