Yeah.
If we start think the procedure of how you get "civilized" in past centuries as Finnish speaking peasant.
1. You were either conscripted, or "conscripted" to the army of king
2. You were signed to the ranks with your Swedish "soldier name" (as Swedish officers couldn't pronounce Finnish names easily), you became "Staal", "Svard", etc. when you were called Matinpoikas, or Nenonens, or...
3. You were forcibly taught the rudimentary Swedish vocabulary as the king's army command tongue
4. You participated to an endless wars at The Kingdom's eastern periferia
5. You survived (unlike countless others of your social 'class') against the odds
6. The King knighted you for your deeds, and your low-noble children spoke Swedish. Your "tax" was to provide soldiers or cavalry for the army.
7. Repeat 1-6 until Finns were exhausted.
8. Retreat from the province, when Finns are killed to the last man. Repeatedly. Let eastern cavalry rape their women (developed under similar circumstances as a battle thralls). Century after century.
9. Make a little brother that takes always every beating for the big brother.
10. Expect they would be always obedient. Expect they would love you. Expect they would give up.
Symbolic value of this win penetrate through the thousands of pages of tomes of Finnish history, written in Swedish.
