John Parricida (German: Johann Parricida) or John the Parricide, also called John of Swabia (Johann von Schwaben), (ca. 1290 – 13 December 1312/13) was the son of the Habsburg duke Rudolf II of Austria and Agnes, daughter of King Ottokar II of Bohemia. By killing his uncle, King Albert I of Germany, he foiled the first attempt of the Habsburg dynasty to install a hereditary monarchy in the Holy Roman Empire.
