 Ultimately, Frederick prevailed in all those conflicts by outliving his opponents and sometimes inheriting their lands, as was the case with Ladislaus, from whom he gained Lower Austria in 1457, and with his brother Albert VI, whom he succeeded in Upper Austria.In 1462, his brother Albert raised an insurrection against him in Vienna and the emperor was besieged in his residence by rebellious subjects.In this war between the brothers, Frederick received support from the King of Bohemia, George of Poděbrady.
