Matthew Csák did not want to accept the king's rule; therefore, he did not attend King Charles' third coronation, when he was crowned with the Holy Crown of Hungary (27 August). Moreover, Matthew Csák still continued to expand the borders of his domains and occupied several castles in the northern part of the kingdom. On 25 June 1311, he led his troops towards Buda and pillaged the surrounding territories and on this account the Cardinal Gentile excommunicated him on 6 July 1311. However, he did not accept the punishment and persuaded some priests to continue their services on his territories.
