Otto I, Duke of Swabia and Bavaria

OTTO (954-Lucca 31 Oct 982, bur Aschaffenburg St Peter and Alexander).  Regino records the birth of "Liutolfo filius Otto" in 954[177].  He was appointed OTTO Duke of Swabia in 973 by his uncle King Otto II in succession to Duke Burkhard III.  "Otto…imperator augustus" confirmed donations of property "de locis Ozenheim, Tetingen…in pago Moiinegouwe in comitatu Eberhardi comitis" by "nobis nepos et equivocus noster Otto dux Sweuorum" to "sancti Petri Ascaffaburg" by charter dated 29 Aug 975[178].  King Otto installed him as OTTO Duke of Bavaria in [976], after confiscating it from his cousin Heinrich II "der Zänker" Duke of Bavaria[179], although Carinthia and the Italian marches were taken from the duchy and made into the new duchy of Carinthia.  "Otto…imperator augustus" donated property in Regensburg to Friedrich Archbishop of Salzburg by charter dated 21 Jul 976 after consulting "Ottonis Bauariorum ducis, nostri…fratris filii"[180].  He campaigned in Italy with his uncle King Otto II.  He took part in the capture of Tarento, and in the battle 13 Jul 982 at which the German army was defeated by a Byzantine/Muslim alliance near Stilo in Calabria[181].  The death of "Otto dux egregius, filius Liudolfi, fratruelis Ottonis secundi", soon after this defeat, is recorded in the Annalista Saxo[182].  The necrology of St Gall records the death "II Kal Nov" of "Ottonis ducis Alamannie"[183].  He is presumably the "Otto dux Sueuorum" whose death is recorded "1 Nov" in The necrology of Merseburg[184].
