Infante Peter, Count of Alburquerque
Peter, infans of Aragón, (1406 – besieging Naples, Italy, 1438), Viceroy of Sicily, 1424–1425, Duke of Noto, was the sixth child of King Ferdinand I of Aragón, and Countess Eleanor Urraca of Alburquerque.
Later king John, Peter, and Henry were a most troublesome princely group, nagging, invading, and fighting all over the lands of his rather peaceful cousin and brother in law, king Juan II of Castile, disrupting, robbing and bringing havoc to the castilian peasants and much opposed to Alvaro de Luna.[clarification needed]
Then, when king Alfonso V of Aragón, the eldest brother, decided to leave Aragón to conquest the kingdom of Naples and live there, leaving his wife, a sister of his much abused and battered cousin the king of Castile, Juan II of Castile, to have some 17 Aragonese - Italian illegitimate children from several Italian nobility women never returning to Spain, his brothers ran with him, too, circa 1432, thirsty for Neapolitan adventures, including the disastrous naval battle of Ponza but also the conquest of Gaeta.[clarification needed] Both Aragonese princes, "Infants" in Spanish, Peter, Duke of Noto, Italy died in battle, aged 32, in Italy, when attacking Naples, and Henry died in Spain, also in battle, aged 45, respectively.
