[1] In contrast, historian Gergely Kiss argued Raynald originated from Belleville in the Kingdom of France (now a neighbourhood in Paris), but this is contradicted by the account of Flemish traveller William of Rubruck.
[2] According to the account of William of Rubruck from 1253, Raynald had an unidentified nephew, who was abducted by the Mongols from Gyulafehérvár (present-day Alba Iulia, Romania) during the 1241–1242 invasion of Hungary and lived in Karakorum when the explorer met him.
[4] A record of the Regestrum Varadinense from 1215 mentions Raynald as provost of Várad too; he judged over a trial by ordeal (of red-hot iron), acquitting the accused local from Gyán.
[5] Historian Dániel Bácsatyai considered Reynald was perhaps also a member of that Hungarian delegation led by John, Archbishop of Esztergom, which was present in England on 7 July 1220, when Thomas Becket's remains were moved from his first tomb to a shrine, in the recently completed Trinity Chapel.
[11] Immediately after his election, Raynald had to deal with the case of the Teutonic Knights, who were granted Burzenland (Barcaság, present-day Romania), the sparsely populated southeastern part of Transylvania by Andrew II in 1211.
When Andrew II confirmed the grant in May 1222, the king emphasized that Burzenland belonged to the sovereignty of his Crown and the knights were also subjects to the authority of the Bishopric of Transylvania.
Although Pope Honorius acknowledged Andrew's charter at the end of 1222, the Teutonic Knights and their Grand Master Hermann von Salza began a diplomatic campaign.
In response (and after a complaint from Hermann von Salza), Pope Honorius reprimanded Raynald with harsh words in December 1223 not to dare to exercise episcopal powers over the territory of Burzenland held by Teutonic Order.
For instance, he made it obligatory for local clerics in Burzenlamd to attend the bishopric's synods and collected tithe not only from Hungarians and Székelys in the region but also from anyone (i.e. German colonists too) who lived there, threatening the resistance with excommunication.
In April 1224, Pope Honorius placed Burzenland and the neighboring territory beyond the Carpathian Mountains, where the Cumans lived (i.e. future Wallachia), under the protection of the Holy See, granting full ecclesiastical autonomy to the Teutonic Order over these lands.
[19] The pope delegated Bulcsú Lád and two other clerics – the Bishop of Cumania (possibly Theodoric) and the provost of Bethlen (present-day Beclean, Romania) – to judge over the lawsuit in November 1235.
When Ugrin Csák asked for permission to establish a Roman Catholic diocese in Syrmia in order to facilitate the conversation of Bosnian heretics, Pope Gregory commissioned Raynald and Desiderius, Bishop of Csanád to investigate the legitimacy of the request.
[21] With the consent of Raynald, the church of Németi (present-day Satu Mare, Romania), inhabited by German colonists, was exempted from the jurisdiction of the archdeacon of Sásvár, and was granted the right of free election of parish priest by Andrew II in 1230.
