to Navarre in early 1329. They were crowned in the Pamplona Cathedral on 5 March. Both were raised on a shield and both threw money during the ceremony. They signed a coronation oath, establishing their royal prerogatives. The charter underlined that Joan was the "true and natural heir" of Navarre, but also declared that "all of the kingdom of Navarre would obey her consort".
