Originally, a patriarch was a man who exercised autocratic authority as a pater familias over an extended family. The system of such rule of families by senior males is termed patriarchy.
The word is derived from Greek πατριάρχης (patriarchēs), meaning "chief or father of a family", a compound of πατριά (patria), meaning "family", and ἄρχειν (archein), meaning "to rule"
Abraham, Isaac, and Jacob are referred to as the three patriarchs of the people of Israel, and the period during which they lived is termed the Patriarchal Age. The word patriarch originally acquired its religious meaning in the Septuagint version of the Bible.
Today, the word has acquired specific ecclesiastical meanings. In particular, the highest-ranking bishops in Eastern Orthodoxy, Oriental Orthodoxy, the Catholic Church (above major archbishop and primate), and the Church of the East are termed patriarchs (and in certain cases also popes). The office and the ecclesiastical circumscription of such a patriarch is termed a patriarchate. Historically, a patriarch has often been the logical choice to act as ethnarch of the community identified with his religious confession within a state or empire of a different creed (such as Christians within the Ottoman Empire).
In the Pentarchy formulated by Justinian I (527–565), the emperor assigned as a patriarchate to the Bishop of Rome the whole of Christianized Europe (including almost all of modern Greece), except for a small area near Constantinople and along the coast of the Black Sea. He included in this patriarchate also the western part of North Africa. Justinian's system was given formal ecclesiastical recognition by the Quinisext Council of 692, which the see of Rome has, however, not recognized.
Popes have in the past occasionally used the title Patriarch of the West, without defining it. Beginning 1863, this title appeared in the annual reference publication, Annuario Pontificio, which in 1885 became a semi-official publication of the Holy See. This publication suppressed the title in its 2006 edition. The Pontifical Council for Promoting Christian Unity explained the decision in a press release issued later that year. It stated that the title "Patriarch of the West" had become "obsolete and practically unusable" and that it was "pointless to insist on maintaining it". Since the Second Vatican Council, the Latin Church, with which the title could be considered associated, is now organized as a number of episcopal conferences and their international groupings.
The Latin Patriarch of Jerusalem
The Patriarch of the East Indies a titular patriarchal see, united to Goa and Daman.
The Patriarch of Lisbon.
The Patriarch of Venice.
The Patriarch of Aquileia – with rival line of succession moved to Grado - dissolved in 1752.
The Patriarch of Grado – in 1451 merged with the Bishopric of Castello and Venice to form the Metropolitan Archdiocese of Venice (later a residential Patriarchate itself).
The Patriarch of the West Indies – a titular patriarchal see, vacant since 1963.
The Latin Patriarch of Antioch – title abolished in 1964.
The titular Latin Patriarch of Alexandria – title abolished in 1964.
The Latin Patriarch of Constantinople – title abolished in 1964.
The Latin Patriarchate of Ethiopia – 1555 to 1663, never effective, only held by Iberian Jesuits
The pope can confer the rank of Patriarch without any see, to an individual Archbishop, as happened on 1676.02.24 to Alessandro Cescenzi, Somascans (C.S.R.), former Latin Titular Patriarch of Alexandria (1671.01.19 – retired 1675.05.27), who resigned the title on 1682.01.09.
Six of the particular Eastern Catholic Churches are headed by a patriarch with a claim to one (or more) of the ancient patriarchal sees:
The Maronite Catholic Patriarch of Antioch and all the East and head of the Maronite Catholic Church
The Chaldean Catholic Patriarch of Babylon and head of the Chaldean Catholic Church
The Metropolitan and Gate of all India and head of the Marthomma Nasrani church
The Melkite Greek Catholic Patriarchate of Antioch and All the East, of Alexandria and of Jerusalem, head of the Melkite Greek Catholic Church; in his case, Antioch is the actual and sole patriarchate, Alexandria and Jerusalem are just titular (once residential) patriarchates vested in his see
The Armenian Catholic Patriarch of Cilicia and head of the Armenian Catholic Church
The Coptic Catholic Patriarch of Alexandria and head of the Coptic Catholic Church
The Syrian Catholic Patriarch of Antioch and all the East and head of the Syriac Catholic Church
Four more of the Eastern Catholic Churches are headed by a prelate known as a "Major Archbishop," a title created in 1963 and essentially equivalent to that of Patriarch:
The Major Archbishop of Kiev-Halych and head of the Ukrainian Greek Catholic Church
The Major Archbishop of Trivandrum and head of the Syro-Malankara Catholic Church
The Major Archbishop of Făgăraş and Alba Iulia and head of the Romanian Church United with Rome, Greek-Catholic
Within their proper sui iuris churches there is no difference between patriarchs and major archbishops. However, differences exist in the order of precedence (i.e. patriarchs take precedence over major archbishops) and in the mode of accession: The election of major archbishops has to be confirmed by the pope before they are allowed to take office. No papal confirmation is needed for newly elected patriarchs before they take office. They are just required to petition the pope as soon as possible for the concession of what is called ecclesiastical communion.

In the Latter Day Saint movement, a patriarch is one who has been ordained to the office of patriarch in the Melchizedek priesthood. The term is considered synonymous with the term evangelist, a term favored by the Community of Christ. In The Church of Jesus Christ of Latter-day Saints, one of the patriarch's primary responsibilities is to give patriarchal blessings, as Jacob did to his twelve sons according to the Old Testament. Patriarchs are typically assigned in each stake and possess the title for life.
