Emperors of the House of Hapsburg

That doesn't necessarily mean he wasn't lawfully the Emperor.

What about the Spanish branch of the Habsburgs? If they had not been deposed in 1714 after the spanish succesion war spain will still be a confederation of independent kingdoms with the same king but with different money, armies, governments....... :( Long live the Habsburgs, the real monarchs of spain, austria, and germany, united by the same kings.

theres no doubt that wilson's insistence on self-determination for the slavs was political grandstanding given British India, the American Philippines, etc-- I don't blame Horthy for opposing Charles since the political reality was that the allies (particularly the Czech-led "Little Entente") would have intervened in any attempt at a restoration (inexplicably). Perhaps it's for the best - had they been restored they would've been deposed or killed by the Communists 20 years later.

The Archduke Otto von Habsburg-Lothringen isn't here because he has never reigned.

I love the imperial austrian anthem. Congratulations for this great video! Thank you so much!
