In 1522, the news came to Nidaros that Walkendorf had died in Rome.
The Cathedral Chapter then unanimously elected on 13 April 1522 Olav Engelbrektsson as the new Archbishop of Nidaros, and he therefore went to Rome for his pallium.
 Just over a month before the election, King Christian II had fled to the Habsburg Netherlands after the nobles revolted with the help from the Duchy of Schleswig - Holstein.
This was known to the Cathedral Chapter when Olav Engelbrektsson was chosen because it still had to send a letter to the King for his approval of the election.
On his way to Rome, Olav stopped in Mechelen, Flanders, for a visit with the King, who had been living in exile in the Duchy of Burgundy, because Christian II was still legally the King of Norway.
 Olav hailed the King, pledged his allegiance to him and delivered the Cathedral Chapter's letter to him.
 He left with the King's approval.

However, for his pallium, Olav had to wait in Rome for the election of the next Pope because Adrian VI had just died on 14 September 1523.
 During his stay, Olav met the Bavarian scholar, Jacob Ziegler, and gave him the information that went into Ziegler's major treatise of geography, Schondia, published in Strasbourg in 1532.
 Engelbrektsson’s statements about his homeland showed his deep sense of nationalism and his distrust of the Danish officials who had been oppressing his homeland.
 When Giulio de' Medici was elected as Pope Clement VII on 19 November 1523, Olav could finally have his pallium and go home.
 He was consecrated as the Archbishop of Nidaros by the new Pope in December 1523.
 On Christmas Day, Olav left Rome for home.

Engelbrektsson probably would not have been the Archbishop of Nidaros, had the King of Denmark had the complete control of Norway.
 But the situation was left unsettled when Christian II fled to exile and Frederick I would not be legally elected by the Riksråd of Norway as the next King of Norway until 1524.
