Information: - An emperor (through Old French "empereor" from ) is a monarch, usually the sovereign ruler of an empire or another type of imperial realm. Empress, the female equivalent, may indicate an emperor's wife ("empress consort"), mother ("empress dowager"), or a woman who rules in her own right ("empress regnant"). Emperors are generally recognized to be of a higher honour and rank than kings. In Europe the title of Emperor was, since the Middle Ages, considered equal or almost equal in dignity to that of Pope, due to the latter's position as visible head of the Church and spiritual leader of Western Europe. The Emperor of Japan is the only currently reigning monarch whose title is translated into English as "Emperor". - For the Portuguese infanta daughter of Sancho I , see : Infanta Constanca of Portugal Infanta Constance of Portugal ( pt : Constanca ; 3 January 1290 -- Sahagun , 18 November 1313 ; Portuguese pronunciation : ( kots ) ; English : Constance ) , was a Portuguese infanta ( princess ) by birth and Queen consort of Castile by marriage .

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. - 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. - Sahagun is a town in the province of Leon, Spain.

Ques:Information: - Professor (commonly abbreviated as "prof.") is an academic rank at universities and other post-secondary education and research institutions in most countries. Literally, "professor" derives from Latin as a "person who professes" being usually an expert in arts or sciences, a teacher of the highest rank. - The University of Oxford (informally Oxford University or simply Oxford) is a collegiate research university located in Oxford, England, United Kingdom. While having no known date of foundation, there is evidence of teaching as far back as 1096, making it the oldest university in the English-speaking world and the world's second-oldest university in continuous operation. It grew rapidly from 1167 when Henry II banned English students from attending the University of Paris. After disputes between students and Oxford townsfolk in 1209, some academics fled northeast to Cambridge where they established what became the University of Cambridge. The two "ancient universities" are frequently jointly referred to as "Oxbridge". - Christ Church (the temple or house, "ds", of Christ, and thus sometimes known as "The House") is a constituent college of the University of Oxford in England. The college is associated with Christ Church Cathedral, Oxford, which serves as the college chapel and whose dean is "ex officio" the college head. - Christopher Brendan Reginald Pelling was the Regius Professor of Greek , at Christ Church , Oxford , from 2003 to 2015 .

They start at the beginning : so many autobiographies open with those depressing words '' I was born ... '' . -- Christopher Pelling , inaugural lecture , 20 May 2004 - The University of Dublin, corporately designated the Chancellor, Doctors and Masters of the University of Dublin, is a university located in Dublin, Ireland. It was founded in 1592 when Queen Elizabeth I issued a charter for Trinity College, as "the mother of a university", thereby making it Ireland's oldest operating university. It was modelled after the collegiate universities of Oxford and of Cambridge, but unlike these only one college was established; as such, the designations "Trinity College" and "University of Dublin" are usually synonymous for practical purposes. - Christ Church Cathedral is the cathedral of the diocese of Oxford, which consists of the counties of Oxford, Buckinghamshire and Berkshire. It is also the chapel of Christ Church at the University of Oxford. This dual role as cathedral and college chapel is unique in the Church of England. - A Regius professor is a university professor with royal patronage or appointment. They are a unique feature of academia in the British Isles. The first Regius professorship was in the field of medicine, and founded by the Scottish King James IV at Aberdeen University in 1497. Regius chairs have since been instituted in various universities, in disciplines judged to be fundamental and for which there is a continuing and significant need. Each was established by a British monarch, and following proper advertisement and interview through the offices of the university and the national government, the current monarch still appoints the professor (except for those at the University of Dublin in Ireland, which left the United Kingdom in 1922). This royal imprimatur, and the relative rarity of these professorships, means a Regius chair is prestigious and highly sought-after.
