Alfonso X, King of Castile and León

Alfonso X (also occasionally Alphonso X, Alphonse X, or Alfons X), 23 November 1221 – 4 April 1284, called the Wise (Spanish: el Sabio), was the King of Castile, León and Galicia from 30 May 1252 until his death. He was of the House of Ivrea, a medieval Frankish dynasty of Burgundian origin which rose to prominence in Italy in the tenth century, even briefly holding the Italian throne. They also ruled the County of Burgundy in the eleventh and twelfth centuries. A cadet branch ruled the Kingdom of Galicia from 1111 and the Kingdoms of Castile and León from 1126 until 1369.

Born in Toledo, Spain, Alfonso was the eldest son of Ferdinand III of Castile and Elizabeth (Beatrice) of Swabia. His mother was the paternal cousin of Holy Roman Emperor Frederick II. His maternal grandparents were Philip of Swabia and Irene Angelina. For the first nine years of his life he was only heir to Castile until his father succeeded his own father Alfonso IX of Leon and united the kingdoms of Castile and Leon. Alfonso succeeded his father as King of Castile and León in 1252.

Of Castile-84 and Castilla-113 appear to represent the same person because: they have the same parents, same siblings, same birth, same death.
