"That makes me wonder. I know, from the timeline of jedi civil war, it was 5 years to kotor.
But to be honest, does anyone have confrimation how long the Mandalorian Wars were?"
Well, if we base our timeline off the Chronicles, the Mandalorean War (#IX) is said to have started in 3,963 BBY. The next Chronicle (X) states its timeframe as 3,961 - 3,956. Now at the begining of X, the mandalorians are in retreat, so we might assume that the war lasted from 3963-3961, aka. 2 years. If we assume that skirmishes lasted the whole of that time (which I don't), then the war lastes 7 years. I definatly lean towards the two year mark.
