[2] Martin had to pay 800 golden florins as servitium commune to the papal court, this relatively low amount reflects the insignificance of the diocese within the Hungarian church hierarchy.
[3] Martin took part in the provincial synod to Udvard, Komárom County (present-day Dvory nad Žitavou, Slovakia), convoked by Archbishop Thomas of Esztergom in May 1307.
[1][5] During the early years of his episcopate, the oligarch Amadeus Aba ruled de facto independently the northern and north-eastern counties of the kingdom, including the overwhelming territory of the Diocese of Eger.
Alongside other lords and prelates, Martin participated with his banderium in the royal campaign, which consisted of successful sieges and the decisive Battle of Rozgony against the Aba dominion in the summer of 1312.
They complained that Martin and his predecessors – Lampert Hont-Pázmány and Andrew – unlawfully seized tithes of altogether approximately 50 villages in Abaúj, Borsod, Ung and Szerencs counties, which belonged to the revenues of the Eger Chapter.
[14] Martin even threatened implicitly his superior, Archbishop Thomas that bypassing the ecclesiastical hierarchy, he appeals directly to the Holy See in the litigation process, in the event of an unfavorable judgment for him.
[14] Around the same time with the lawsuit between Martin and his cathedral chapter, the Hungarian monarch concluded a short-lived peace with the oligarch Matthew Csák, who thus was able to retain several captured Church properties in Upper Hungary, which had mostly belonged to the Archdiocese of Esztergom and its suffragans.
In response to Charles' actions, who seized church incomes to finance his war against the oligarchs, the prelates of the realm – including Martin – summoned a national synod to Kalocsa and made an alliance in the spring of 1318 against all who would jeopardize their interests.
[11] According to István Sugár, the need for united action by the prelates in national politics at the turn of 1317 and 1318 put severe pressure on Martin to retreat from his stubborn stance during the trial.
[12][16] As before with Amadeus Aba, Martin also sought to establish good relations with Philip Drugeth, the new lord of Northeast Hungary, who was considered the most faithful confidant of Charles.
Philip requested the bishop to allow 40 days of absolution to the newly erected St. Ladislaus chapel of the Pauline hermits near Középnémeti in 1319 (today a borough of Milhosť in Slovakia).
