On Mandalore the rulers are called Mandalore's. This is one thing I don't get if they are ruled by them then how is Dutchess Santine the ruler? She isn't a Mandalore I don't think, is she i dought it.
There were many mandalores
Mandalore the Indomitable
Mandalore the Preserver
Jaster Mereel
Jango Fett (Before Bounty Hunter)
Boba Fett (Befor Gnome Virus plagued Mandalore.)
Feel free to post pics of known Mandalores or more of those already posted.
