Royalty and Transylvania

Can anyone name how many princes of Transylvania there have been?

Who would be the greatest?

Here are some names: Emperor of Austria, King of Hungary, Prince of Transylvania, Joesph

Micheal the Brave Prince of Wallachia, Prince of Moldavia, Prince of Transylvania

There is no Prince of Transylvania at the present time, as Otto von Hapsburg is the pretender to the title of Prince of Transylvania.

Yes there were many, and yes you can find it on wikipedia.

Have fun!
