An episcopal see is the ecclesiastical domain of authority of a Bishop. The diocese is the key geographical unit of authority in the form of church governance known as episcopal polity. Episcopal polity is a form of church governance which is hierarchical in structure with the chief authority over a local Christian church resting in a Bishop (Greek In the Roman Catholic Church and the Anglican Communion, an important diocese is called an archdiocese (usually due to size, historical significance, or both), which is governed by an Archbishop, who may be exempt from or have Metropolitan authority over the other ('suffragan') dioceses within a wider jurisdiction called an ecclesiastical province.

In the later organization of the Roman Empire, the increasingly subdivided provinces were administratively associated in a larger unit, the diocese (Latin dioecesis, from the Greek term διοίκησις, meaning "administration"). A bishop is an ordained or consecrated member of the Christian clergy who is generally entrusted with a position of authority and oversight The Roman Empire was the post-Republican phase of the ancient Roman civilization, characterised by an autocratic form of government and large territorial In Ancient Rome, a province (Latin provincia, pl provinciae) was the basic and until the Tetrarchy (circa A Roman or civil diocese ( Latin: dioecesis, from the διοίκησις, "administration" was one of the administrative divisions Latin ( lingua Latīna, laˈtiːna is an Italic language, historically spoken in Latium and Ancient Rome.

With the adoption of Christianity as the Empire's official religion in the 4th century, the clergy assumed official positions of authority alongside the civil governors. A formal Church hierarchy was set up, parallel to the civil administration, whose areas of responsibility often coincided. With the collapse of the Western Empire in the 5th century, the bishops in Western Europe assumed a large part of the role of the former Roman governors. The Western Roman Empire refers to the western half of the Roman Empire, from its division by Diocletian in 285 the other half of the Roman Empire was the Eastern A similar, though less pronounced, development occurred in the East, where the Roman administrative apparatus was largely retained by the Byzantine Empire. In modern times, many an ancient diocese, though later divided among several dioceses, has preserved the boundaries of a long-vanished Roman administrative division. For Gaul, Bruce Eagles has observed that "it has long been an academic commonplace in France that the medieval dioceses, and their constituent pagi, were the direct territorial successors of the Roman civitates. In the later Western Roman Empire, following the reorganization of Diocletian, a pagus (compare French pays, Spanish pago In the history of the Roman empire, civitas (pl civitates mainly referred to the condition of Roman Citizenship It was also used to describe a type of settlement 
Modern usage of 'diocese' tends to refer to the sphere of a bishop's jurisdiction. This became commonplace during the self-conscious "classicizing" structural evolution of the Carolingian empire in the 9th century, but this usage had itself been evolving from the much earlier parochia ("parish"), dating from the increasingly formalised Christian authority structure in the 4th century (see EB 1911). Carolingian Empire is a historiographical term sometimes used to refer to the realm of the Franks under the Carolingian dynasty. A parish is a Local church; it is an administrative unit typically found in episcopal or presbyterian churches
In the Methodist Church (Covering Great Britain and Ireland), churches are grouped together in sections. Sections are grouped together to form Circuits. Circuits are grouped together to form Districts. All of these, combined with the local membership of the Church, are referred to as the 'Connexion'. This, 18th century term, endorsed by John Wesley describes how people serving in different geographical centres are 'connected' to each other. The Methodist Church has an annual president. Each District is headed by a 'Chair' who oversees its functioning. Each Circuit is governed by a superintendent minister. The geographical regions covered by circuits and dioceses rarely overlap.
In the United Methodist Church, a bishop is given oversight over a geographical area called an Episcopal Area. The United Methodist Church is the largest Methodist denomination and the second largest Protestant denomination in the United States. A bishop is an ordained or consecrated member of the Christian clergy who is generally entrusted with a position of authority and oversight An Episcopal Area in the United Methodist Church (UMC is a basic unit of this denomination Each Episcopal Area contains one or more Annual Conference, which is how the churches and clergy under the bishop's supervision are organized. An Annual Conference in the United Methodist Church is a regional body that governs much of the life of the "Connectional Church Thus, the use of the term "diocese" referring to geography is the most equivalent in the U. M. Church, whereas each Annual Conference is part of one Episcopal Area (though that Area may contain more than one Conference).
In The Church of Jesus Christ of Latter-day Saints, a bishop is not the leader of a large administrative area, but is rather the spiritual leader of an individual local congregation (known as a ward and roughly equivalent to a Catholic parish). The Church of Jesus Christ of Latter-day Saints is the fourth largest Christian denomination in the United States and the largest and most well-known Bishop is the highest priesthood office of the Aaronic priesthood in the Latter Day Saint movement.

A stake is an administrative unit composed of multiple congregations in denominations of the Latter Day Saint movement.
