Jaromír even attacked the new bishop of Olomouc and carried off by force of arms the relics which had been removed from Prague to the new see.
Pope Alexander II sent the legate Rudolph to hold a diet in Prague in response to the conflicts surrounding the new see.
Jaromír was an ally of Holy Roman Emperor Henry IV during the Investiture Controversy.
In 1085, John died, and a Reichstag convened in Mainz to suppress the Moravian see, re-uniting it to Prague by Jaromír's insistence.
Vratislaus fell out with Henry over the loss of Meissen and raised his chaplain Wecel to Olomouc as Bishop Andrew I. Jaromír went to Rome to protest to Pope Urban II.
