Please answer this: Information: - Infanta Maria of Portugal ( Portuguese pronunciation : ( mi ) ) ( 9 February 1313 -- 18 January 1357 ) was a Portuguese infanta ( princess ) , Queen consort of Castile upon her marriage to Alfonso XI in 1328 , and mother of King Peter of Castile . She was the first daughter of King Afonso IV of Portugal and his first wife Beatrice of Castile . Her maternal grandparents were Sancho IV of Castile and Maria de Molina . - Alfonso XI of Castile (13 August 131126/27 March 1350), called the Avenger ("el Iustecero"), was the king of Castile, Leon and Galicia. He was the son of Ferdinand IV of Castile and his wife Constance of Portugal. Upon his father's death in 1312, several disputes ensued over who would hold regency, which were resolved in 1313. - A title is a prefix or suffix added to someone's name in certain contexts. It may signify either veneration, an official position or a professional or academic qualification. In some languages, titles may be inserted before a last name (for example, "Graf" in German, Cardinal in Catholic usage or clerical titles such as Archbishop). Some titles are hereditary. - James I the Conqueror (Catalan: "Jaume el Conqueridor", Aragonese: "Chaime lo Conqueridor", Occitan: "Jacme lo Conquistaire", Spanish: "Jaime el Conquistador"; 2 February 1208 27 July 1276) was King of Aragon, Count of Barcelona, and Lord of Montpellier from 1213 to 1276; King of Majorca from 1231 to 1276; and Valencia from 1238 to 1276. His long reign -the longest of any Iberian monarch- saw the expansion of the House of Aragon in three directions: Languedoc to the north, the Balearic Islands to the south, and Valencia to the southwest. By a treaty with Louis IX of France, he wrested the county of Barcelona from nominal French suzerainty and integrated it into his crown. His part in the Reconquista was similar in Mediterranean Spain to that of his contemporary Ferdinand III of Castile in Andalusia. - Afonso IV (8 February 129128 May 1357), called the Brave, was King of Portugal and the Algarves from 1325 until his death. He was the only legitimate son of King Denis of Portugal by his wife Elizabeth of Aragon. - Sancho IV of Castile (12 May 1258 25 April 1295) called the Brave ("el Bravo"), was the King of Castile, Leon and Galicia from 1284 to his death. He was the second son of Alfonso X and Yolanda, daughter of James I of Aragon. - Denis (; Lisbon, 9 October 1261 Santarem, 7 January 1325), called the Farmer King ("Rei Lavrador") and the Poet King ("Rei Poeta"), was King of Portugal and the Algarve. The eldest son of Afonso III of Portugal by his second wife, Beatrice of Castile, and grandson of king Alfonso X of Castile (known as the Wise), Denis succeeded his father in 1279. His marriage to Elizabeth of Aragon, who was later canonised as a saint of the Roman Catholic Church, was arranged in 1281 when she was 10 years old. - Maria Alfonso Tellez de Menezes (c. 1265 1321), known as Maria de Molina, was the wife of Sancho IV of Castile. She was queen consort of Castile and Leon from 1284 to 1295, and served as regent for her minor son Ferdinand IV (1295 - c.1301) and later her grandson Alfonso XI of Castile (1312-1321). - A queen consort is the wife of a reigning king (or an empress consort in the case of an emperor). In Brunei, the wife of the Sultan is known as a "Raja Isteri" with prefix "Pengiran Anak", equivalent with queen consort in English, as were the consorts of tsars when Bulgaria was still a monarchy. A queen consort usually shares her husband's social rank and status. She holds the feminine equivalent of the king's monarchical titles, but historically, she does not share the king's political and military powers. A queen regnant is a queen in her own right with all the powers of a monarch, who (usually) has become queen by inheriting the throne upon the death of the previous monarch. - Elizabeth of Aragon, also known as Elizabeth of Portugal, T.O.S.F. (1271 4 July 1336; "Elisabet" in Catalan, "Isabel" in Aragonese, Portuguese and Spanish), was queen consort of Portugal, a tertiary of the Franciscan Order and is venerated as a saint of the Roman Catholic Church.
