Except:

Nine of the Catalans on trial for their efforts to achieve independence received between nine and 13 years in prison for sedition. Four of them were additionally convicted for misuse of public funds, and three more were fined for disobedience. The Spanish Constitution says the country can’t be divided.

I’m reminded of the short story by H. Beam Piper, an early alternate reality story, written about 70 years ago:

All the world knows that the American Patriots lost their war for independence from England; that their army was shattered, that their leaders were either killed or driven into exile. How many times, when I was a little boy, did I not sit up long past my bedtime, when old Baron von Steuben was a guest at Tarlburg-Schloss, listening open-mouthed and wide-eyed to his stories of that gallant lost struggle! How I used to shiver at his tales of the terrible winter camp, or thrill at the battles, or weep as he told how he held the dying Washington in his arms, and listened to his noble last words, at the Battle of Doylestown! And here, this man was telling me that the Patriots had really won, and set up the republic for which they had fought! I had been prepared for some of what Hartenstein had called unrealistic beliefs, but nothing as fantastic as this.

If the Catalans had won their bid for independence, they would be feted as national heroes today. Moral of the story is don’t do it unless you have a realistic chance of winning. They did not.
