[2][3][4] At Nördlingen, Conrad IV granted Egno a privilege stating that nobody could cross the duchy of Brixen without the permission of either the emperor, the king or the bishop.
A letter written by Albert von Behaim confirms that Egno had closed the passes by September 1240, greatly hampering communication between the Pope and his German allies.
[4] In April 1245, Egno was in Vienna aiding the negotiations between the Emperor and Duke Frederick II of Austria for the former's marriage to the latter's niece, Gertrude.
He had to fight the podestà Sodeger de Tito and Ezzelino III da Romano for control of his bishopric.
[1] The death of Ezzelino in 1259 brought respite to Egno, but in 1265 he faced a rebellion in Trent and had to flee to Riva del Garda.
[3] On 21 April 1263, Egno enfeoffed Louis II, Duke of Bavaria, with the fiefs that had escheated to the bishopric on the death of Count Siboto VI of Falkenstein.
