LOL! They were not mentioned in the movies, the wars happened before the movies. You also have to understand that there have been tons of shows/animated movies/games that have come out too concerning the Star Wars universe. "The Mandalore Plot" is the twelfth episode in Season Two of the Star Wars: The Clone Wars television series. It aired on January 29, 2010 and is the first of a three-part storyline. LOL! AND SORRY I MEANT TO SAY: And btw, Beskar, the armor the Mandalorians wear can NOT be cut by almost nothing, including a light saber. Edit: Wait, that reads right, basically Beskar is almost indestructible. Can I just say, just because you were born after Windows 3.1 does not mean Windows 3.1 never existed. I don't know, maybe I might be wrong, but at least I have sources to pull from, not just saying "to my knowledge" and "from my memory" and the notorious "I don't recall".
