Otto I, Duke of Swabia and Bavaria

[1] The Duchy of Carinthia and the March of the Nordgau were also taken from Henry, but were not bestowed on Otto, thus their history is separate from that of Bavaria from this point on.

[1] The army of Bavarians that was ambushed by Boleslaus I of Bohemia near Plzeň while on its way to join the emperor at this time may have been sent by Duke Otto.

[2][3] In 980 Otto accompanied the emperor on his south Italian campaign, fighting both the Byzantines and the Sicilian Arabs.

Assigned to take the news of the campaign back to Germany, he died en route, of wounds received in battle, either 31 October or 1 November, at Lucca.

His family brought his body back and had it buried in the collegiate church of Saints Peter and Alexander at Aschaffenburg, which Otto had generously endowed.
