Diocese of Stockholm in 1942. Historical significance and royal connections Storkyrkan has been the venue of important events in the history of Sweden. The growing wealth and influence of Stockholm during the Middle Ages, and the church's vicinity to the Royal Palace, attracted the attention of both the Archbishop of Uppsala and the monarchs of Sweden. The archbishop occasionally appointed a special representative to the church, and frequently intervened in local church matters. On at least one occasion, in 1338, a bishop (Hemming of Turku) was ordained in Storkyrkan. The Reformation in Sweden was at least partly born in Storkyrkan: it was here that Lutheranism was publicly preached for the first time in Sweden and Storkyrkan was at the same time the first church in Sweden where Mass was celebrated in Swedish (instead of Latin), in 1525. One of the main advocates of the Reformation in Sweden, Olaus Petri, then served as a priest in Storkyrkan. As Storkyrkan from then on was used exclusively by the Swedish-speaking congregation of Stockholm, the sizeable German and Finnish-speaking congregations also moved out to the German Church and a chapel in the town hall, respectively. The church has been used for the coronation of kings and queens of Sweden on several occasions. The first royal coronation that took place in Storkyrkan was the coronation of Magnus IV and Blanche of Namur in 1336. The coronation was conducted by , Bishop of Tartu, in the presence of all Swedish bishops. Most medieval coronations however took place in Uppsala Cathedral. The next time a coronation took place in Storkyrkan was in 1497, when King John was crowned King of Sweden there, during the Kalmar Union. His son Christian II of Denmark was crowned in Storkyrkan on 4 November 1521 in a ceremony designed to mark the submission of Sweden to the rule of King Christian. During the ceremony, representatives of Emperor Charles V presented the king with the Order of the Golden Fleece. Just a few days later, the Stockholm Bloodbath took place. For some time it was then considered inauspicious for ruling monarchs to be crowned in Storkyrkan. However, the wedding between King Eric XIV of Sweden and Karin Månsdotter, as well as her coronation following the wedding, took place in Storkyrkan in 1568. Maria Eleonora of Brandenburg was also crowned as Queen of Sweden in Storkyrkan, following her marriage to King Gustavus Adolphus in
