James, Bishop of Nyitra

He pledged a portion in the village Keltkő (later Zsitvatő, present-day a borough of Radvaň nad Dunajom, Slovakia) and a surrounding fishpond along the Danube in 1226.

Upon the request of King Andrew II of Hungary, he donated Lelőc to the Crown and subsequently he was compensated with the estate Nádas (today Nedašovce, Slovakia), then an accessory of the castle of Nyitra, in 1232.

[4] King Andrew II of Hungary persuaded his heir and eldest son Béla to separate from his wife, Maria Laskarina in 1222.

[5][6] James again performed a diplomatic mission in the winter of 1228, when took a journey to Velehrad, where Ottokar I of Bohemia confirmed the privileges of the local Cistercian monastery.

Two rival factions emerged in the following months: a large part of the canons nominated Bishop Desiderius of Csanád, while some members of the college supported the candidacy of James.

[10] Pope Gregory IX delegated him to judge in the various stages (1227–1228, 1235) of a harsh litigation between the Pannonhalma Abbey and a Hungarian lord Demetrius Csák regarding the right of ownership over the castle Németújvár (present-day Güssing, Austria).

[11] When John, Bishop of Bosnia, put Hungary under a new interdict in the first half of 1234, because Andrew had not dismissed his non-Christian officials despite his oath of Bereg, Pope Gregory ordered Ugrin Csák, Archbishop of Kalocsa, James of Nyitra and Abbot Uros of Pannonhalma to investigate the case.

[12] According to Roger of Torre Maggiore's Carmen miserabile, James was one of the prelates, who was killed in the disastrous Battle of Mohi on 11 April 1241, during the first Mongol invasion of Hungary.
