Prefect (from the Latinpraefectus, perfect participle of praeficere: "make in front", i.e., put in charge) is a magisterial title of varying definition, but which, basically, refers to the leader of an administrative area.
A prefect's office, department, or area of control is called a prefecture, but in various post-Roman empire cases there is a prefect without a prefecture or vice versa. The words "prefect" and "prefecture" are also used, more or less conventionally, to render analogous words in other languages, especially Romance languages.
Praefectus, often with a further qualification, was the formal title of many, fairly low to high-ranking, military or civil officials in the Roman Empire, whose authority was not embodied in their person (as it was with elected Magistrates) but conferred by delegation from a higher authority. They did have some authority in their prefecture such as controlling prisons and in civil administration.
As Egypt was a special imperial domain, a rich and strategic granary, where the Emperor enjoyed an almost pharaonic position unlike any other province or diocese, its head was styled uniquely Praefectus Augustalis, indicating that he governed in the personal name of the august emperor.
Praefectus Sarmatarum gentilium (from the steppes, notably in Italy)
Praefectus urbi: a prefect of the republican era who guarded the city during the annual sacrifice of the Latin: feriae latina on Mount Alban in which the Consuls participated. His former title was "custos urbi" ("guardian of the city").
Especially in Medieval Latin, præfectus was used to refer to various officers—administrative, military, judicial, etc.—usually alongside a more precise term in the vernacular (such as Burggraf).
The term is used by the Catholic Church, which based much of its canon law terminology on Roman law, in several different ways.
The Roman Curia has the nine Prefects of all the Congregations as well as the two of the Papal Household and of the Economic Affairs of the Holy See.
The title also attaches to the heads of some Pontifical Council (central departments of the Curia), who are principally titled president, but in addition there is sometimes an additional ex officio position as a prefect. For example the president of the Pontifical Council for Interreligious Dialogue is also the prefect of the Commission for Religious Relations with Muslims.
Traditionally these Curial officials are Cardinals, hence often called "Cardinal-Prefect" or "Cardinal-President". There was a custom that those who were not cardinals when they were appointed were titled "Pro-Prefect" or "Pro-President". Then these officials would be appointed prefect or president after their elevation to the Sacred College. However, since 1998, this custom has fallen into disuse.
A Prefect Apostolic is a cleric (sometimes a Titular Bishop, but normally a priest) in charge of an apostolic prefecture, a type of Roman Catholic territorial jurisdiction fulfilling the functions of a diocese, usually in a missionary area or in a country that is anti-religious, such as the People's Republic of China, but that is not yet given the status of regular diocese. It is usually destined to become one in time.
In the context of schools, a prefect is a pupil who has been given limited authority over other pupils in the school, similar to the authority given to a hall monitor or safety patrol member.
In some British and Commonwealth schools (especially but not exclusively Independent schools), prefects, usually students in fifth to seventh years (depending on how many years the school in question has), have considerable power; in some cases they effectively run the school outside the classroom. They were once even allowed to administer school corporal punishment in some schools (now abolished in the UK and several other countries). They usually answer to a senior prefect known as the Head of School (though in Canada, Head of School is more often seen as a gender-neutral term for headmaster or headmistress) or Head Prefect or Head Boy or Head Girl or Senior Prefect. Larger schools may have a hierarchical structure with a team of prefects, a team of senior prefects, and a Head Boy and Girl. The Head Prefect may also be the School Captain if that is an appointed position in the school. However, due to Health and Safety laws the staff have tended to become stricter about what responsibilities prefects may hold, for fear of being held responsible in case of litigation. This system is also practised in Hong Kong, a former British colony.
In India, Pakistan, Sri Lanka, Singapore and Malaysia, prefects are student leaders in primary and secondary schools, often along the lines of other Commonwealth schools, but with superior powers. The prefect systems in these countries have changed little from when they were under the British, as the present governments have seen them as effective.
In Sweden, a prefect (prefekt) is the head of a university department.
In Jesuit and other Catholic schools this title was given formerly to members of the faculty, a prefect of discipline in charge of student attendance, general order and such, and a prefect of studies in charge of academic issues.
Many college preparatory boarding schools utilize the position of Prefect as a high student leadership position.
Modern sub-national administration
In Albania a prefect (Prefekti) is the State's representative in a region (qark). His agency is called the Prefektura. Albania have 12 prefects in 12 prefectures, appointed by the Prime Minister of Albania and the Government.
In France (and some former French or Belgian colonies, such as Rwanda), a prefect (préfet) is the State's representative in a département. His agency is called the préfecture, and his circumscription is also called a prefecture in some former French republics. Sub-prefects (sous-préfets, sous-préfecture) operate in the arrondissements under his control. In Paris, the prefect of police is the head of the city's police.
In Italy, a prefect (prefetto) is the State's representative in a province. His office is called Prefettura - Ufficio Territoriale del Governo . They have political responsibility and coordinate the local quaestor (Questore), who has technical responsibility, to enforce laws when public safety is threatened. The office existed in the Italian states before the Italian unification (1861), with various names (e.g., in the Kingdom of Two Sicilies the name was "intendente"); the born of the office, in the Italian system, dates from the times on Napoleonic occupation on Italy (1802), so it celebrated 200 years of life in 2002; the current name dates from 1861, under the government of Bettino Ricasoli, when a law extended the Kingdom of Sardinia administrative system to whole of Italy. In the early years the job entailed a more vigorous and continuous application of central state authority in imposing regulations in the fields of education, public works, sanitary provision and the nomination of mayors and provincial deputies. Today it plays an intermediary role between the municipalities and other local governments.
In some Spanish-speaking states in Latin America, following a French-type model introduced in Spain itself, prefects were installed as governors; remarkably, in some republics (like Peru) two levels were constructed from the French model: a prefecture and a department, the one being only part of the other.
In Greece a prefect (nomarhis, νομάρχης) used to be the elected head of one of the 54 prefectures (nomarhies, νομαρχίες), which were second-level administrative divisions, between the first-level Peripheries (periferies, περιφέρειες) and the third-level Municipalities (demoi, δήμοι), until their abolition with the Kallikratis reform in 2010. The Prefectural elections (popular ballot) would be held every four years along with the Municipal elections. The last Prefectural elections in Greece were held in October 2006.
In Romania, a prefect (prefect) is the appointed governmental representative in a county (judeţ) and in the Municipality of Bucharest, in an agency called prefectură. The prefect's role is to represent the national government at local level, acting as a liaison and facilitating the implementation of National Development Plans and governing programmes at local level.
In Brazil, a prefect (prefeito) is the elected head of the executive branch in a municipality. Larger cities, such as São Paulo, Rio de Janeiro, Curitiba, etc., also have sub-prefects, appointed to their offices by the elected prefect.
In Georgia, a prefect (პრეფექტი) was the head of the executive branch in a municipality, appointed by the President of Georgia from 1990 to 1992.
