Louis Fadrique

Louis Fadrique (also Luis or Lluís Frederic d'Aragó; died 1382) a Catalan nobleman who was Count of Salona, as well as lord of various other towns in Central Greece from ca. 1365 until his death in 1382. In 1375–1381 he also served as the vicar-general of the twin duchy of Athens and Neopatras.

Louis was the son of James Fadrique and a grandson of Alfonso Fadrique. When his father seized the fortress of Siderokastron in 1365, Louis became its castellan, although he was underage. When James died in 1366, Louis in addition received possession of the nearby town of Zetouni. Following the machinations of the agents of the then vicar-general, Roger de Llúria, in June 1367 King Frederick III of Sicily ordered Louis to surrender Siderokastron to Nicholas de Sosa, but Louis seems to have disregarded this and maintained control of the fortress throughout his life. In ca. 1368 he married Helena Asanina Kantakouzene, daughter of Matthew Kantakouzenos, the former Byzantine co-emperor (1353–1357). The couple had one daughter, Maria.

Louis also came into conflict with his uncle, Boniface Fadrique, to whom James had willed "all his rights and properties" in the Duchy of Athens, including the County of Salona with Loidoriki and Veteranitsa, and the island of Aegina, which Boniface gave his son Peter. With the support of most of the Catalan feudatories, rattled following the capture of Megara by the Florentine adventurer Nerio I Acciaioli, in April 1375, Louis obtained from Frederick III his appointment as vicar-general of the twin duchy of Athens and Neopatras. He had apparently exercised the duties of the office since the death or incapacitation of his rather incompetent predecessor, Matthew of Peralta, in the previous year; and would remain in office until the autumn of 1381. From this position, Louis was able to defeat his uncle and cousin when they took up arms against him. Louis took over their properties, and sent Peter to exile and prison in Aragon. His uncle Boniface died soon after sometime before September 1380.
