I never knew what the lyrics was about. Thank you. Your article led me to this article below, and I had a blast reading it.

King Louis VXI was truly a remarkable king. His death marks the end of a great European monarchy, and I can see that the propaganda destroying great people today, is of the same caliber as the propaganda who wanted to destroy this king, even beyond his grave. He went to his death with a repenting heart, but with his noble dignity intact. His legacy also belongs to the Polish people.

The irony is that the liberty people brag about was actually lost with his death. But many are to indoctrinated to see that this so called democracy has enslaved them more than anything. It’s what you get for turning your back on God, I reckon.
