Final Fantasy XII
Final Fantasy XII takes place in Dalmasca. Princess Ashe of Dalmasca and Prince Rasler of Nabradia had been married for a short time when the Archadian Empire invaded Dalmasca.  A war started thereafter, and Archadia took over Dalmasca in no time, for the small country of Dalmasca stood no chance against the massive Archadian Empire.  While the war was going on, Prince Rasler died, leaving Princess Ashe alone.  The king of Dalmasca, Ashe's father, decided to surrender  to Archadia, clinging to dreams of peace. However, Archadia's ruler wanted him dead as soon as the treaty was signed. Knights from Dalmasca tried to rescue him, but one of the captain of the knights, Basch, was replaced by his twin brother, who then killed king Raminas of Dalmasca, and the main character's older brother Reks.  Basch's twin brother is a "Judge" who works for Archadia. The real Basch is accused of high treason and is supposedly killed. Princess Ashe went into hiding afterwards, and was deemed dead.
