THE DATE AND location of Coloman's coronation is nowhere mentioned in our sources. We know it happened and a few details are revealed thanks to four charters: two letters of Andrew II written to Pope Innocent III, a diploma of Honorius III, and a grant from the Hungarian sovereign to Demeter of the Aba kindred, one of the officials of the newly crowned Coloman. The last two sources were issued long after the events (in 1222 and 1234), and neither reveal the location nor the date, but do confirm the fact of the enthronement.

The first royal letter sent to Innocent III is dated to 1214 and must have followed the Scepus Council. Andrew II intended to handle several items. First, he requested papal permission for Coloman to be crowned king of Galicia by Archbishop John of Esztergom (filium nostrum […] in regem inungat). The second letter was meant to offer thanks for the received licence and formulated a petition for a golden crown for Coloman (coronam auream Regie dignitati congruentem filio nostri conferre). Furthermore, the Hungarian king promised to send a clergyman from Galicia to participate at the Fourth Lateran Council. The council started in November 1215, so the royal letter was probably written in August, at the very latest.

Regarding the coronation, while in the Kingdom of Hungary the reigning archbishop of Esztergom had the right to conduct the enthronement, this privilege concerned solely the Hungarian kings and it did not require papal permission. The case of Coloman was different; it was a new phenomenon with no precedent, and therefore papal licence was essential. Innocent III's approval was intended to be secured using the formulation of a request that it was motivated by the local elite and people, who were eager to join the Roman Church (Galiciae principes et populus, nostri ditioni subiecti humiliter a nobis postularunt). The Scepus Agreement was not even mentioned in the first letter, whereas the second mentions a matrimonial contract (contractum) and asks for papal mediation to convince Leszek to send help for Coloman, who was under siege in the castle of Halych.
