Radiàalso known as Radich Postupovich (; fl. 1413âÂÂ1441) was a Serbian nobleman that had the title of Grand ÃÂelnik (count palatine), the highest dignitary after the Serbian monarch. He began his service under Prince, later Despot, Stefan Lazarevià(r. 1389âÂÂ1427) as ÃÂelnik, then was elevated to Grand ÃÂelnik during the rule of Despot ÃÂuraàBrankovià(r. 1427âÂÂ1456). He was very wealthy, and held the silver mines in Novo Brdo of the Serbian Despotate. Radiàfounded and renovated several churches and monasteries which still exist, including the notable VraÃÂevà ¡nica and Kastamonitou. He took monastic vows and became a monk in Kastamonitou where he spent his last years.
He held the highest position, under Stefan LazareviÃÂ and ÃÂuraÃÂ BrankoviÃÂ, and was the longest office-holder (ÃÂelnik), and the most powerful political figure besides the monarch in his time.
Radiàwas born in ca. 1363 or 1372, in the village of Kamenica, to a family of miners, who extracted lead, zinc and silver from the Rudnik mine. RadiÃÂ's father was vojvoda Milutin, a lord of Gruà ¾a. He was brought up at the court of Prince Lazar of Serbia and was friends with the heir, Stefan. At the age of 17, he joined his father's contingent and fought at the Battle of Kosovo (1389) under the command of Prince Lazar against Ottoman Sultan Murad I; according to tradition he prayed to Saint George and promised that if he would survive, he would found the VraÃÂevà ¡nica monastery as a sign of gratitude. Some older soldiers made fun of his age, but he survived without a scratch, and became glorified as the strongest and most courageous fighter of the younger generation. The bulk of both armies were wiped out in the battle, including Prince Lazar and Murad I; although the Ottomans annihilated the Serbian army, they also suffered high casualties which delayed their progress. Serbs were left with too few men to effectively defend their lands, while the Turks had many more troops in the east. Consequently, the Serbian principalities that were not already Ottoman vassals, one after the other became so in the following decades.
Radiàhad the title of ÃÂelnik under Despot Stefan LazareviÃÂ. Stefan Lazareviàwrote two charters in 1405, which granted Radiàpossessions. In the same year Despot Stefan wrote a charter "from the glorious city of BoraÃÂ", which was held by RadiÃÂ. Radiàheld a great estate in Upper Gruà ¾a, at the foot of the Rudnik, where he would later found VraÃÂevà ¡nica. He and Despot Stefan led the Serbian army that supported Mehmet I and defeated Musa ÃÂelebi at the Battle of ÃÂamurlu (Ottoman Interregnum) in 1413. He held not only Rudnik and its surroundings; he received 70 villages in, among others, BraniÃÂevo and KiÃÂevo by Despot Stefan.
RadiÃÂ was elevated to Grand ÃÂelnik during the rule of ÃÂuraÃÂ BrankoviÃÂ, in the first half of 1429. The Grand ÃÂelnik was the highest court title of the Serbian Despotate, and the title-holders held great provinces, property, and honours, and RadiÃÂ was one of the most powerful ones.
RadiÃÂ's lands were the mines in Novo Brdo and Rudnik, and the city of Koznik. Radiàheld the Rudnik area (), which had the villages of BeluÃÂa, Prodanovci, Kamenica, à  umeni and Vlasi Vojkovci; He founded the VraÃÂevà ¡nica Monastery in 1428âÂÂ1429, which lied below the Rudnik, in VraÃÂevà ¡tica, which was composed out of five villages: Gornja and Donja (Upper and Lower) VraÃÂevà ¡tica (VraÃÂevà ¡nica), Grahovac, Konjuà ¡a and Brezova. According to tradition, Radiàlived in BeluÃÂa, which later was called and still today bears the name "CrnuÃÂa" (Gornja and Donja), after all of its male adults fell at the Battle of Kosovo, besides Radià(belo â "white", crno â "black"). Radiàalso received possessions in Banatska Crna Gora.
Radiàalso founded the monastery of the Great Annunciation (Veliko Blagoveà ¡tenje) in the village of Grabovica, near Gornji Milanovac, sometime before 1429âÂÂ30. The church dedicated to St. Archangel Gabriel in BoraÃÂ, in KniÃÂ, has an inscription dated to 1553 which name him as the founder. The Milentija monastery, in Milentija, which is mentioned in one of Radiàcharters dated 1430, was possibly founded by him.
In a 1433 charter issued to Vatopedi by RadiÃÂ, confirmed by Despot ÃÂuraÃÂ, RadiÃÂ held the village of Halae, while Stevan RatkoviÃÂ held Cerovac, in the province of Nekudim. RadiÃÂ did not stop at founding and renovating churches in his home region, as soon as he had gained wealth and status, he started reaching out to far away churches, as an example of the past noblemen and dynastic members. hegoumenos Neophytos persuaded RadiÃÂ to contribute to the restoration of Kastamonitou Monastery on Mount Athos. He became the second ktitor, and then took monastic vows and received the name Roman (after 1433). His spiritual bishop at that time was Marko, the Bishop of Arilje. RadiÃÂ spent his last years in Kastamonitou as a monk, the monastery then became Serbian.
He was alive in 1441, and is believed to have died before 1456, when Despot ÃÂuraàand his son Lazar Brankovià(1456âÂÂ1458) gifted RadiÃÂ's Church of St. George in VraÃÂevà ¡nica to Metropolitan Venedikt. Radiàwas buried in his endowment of VraÃÂevà ¡nica.
He married Ana, and had a son, Mihailo.
He is the mythological progenitor of the RadiÃÂ-Postupoviàfamily (àðôøÃÂ-ÃÂþÃÂÃÂÃÂÿþòøÃÂ), which produced several Orthodox clerics. In Serbian epic poetry, Radiàis called Rade OblaÃÂià(àðôõ ÃÂñûðÃÂøÃÂ) or Oblak Radosav (ÃÂñûðú àðôþÃÂðò), and also Rajko od Rasine ("Rajko from Rasina").
