Question: What title is used for the leader of the church that the Anglican Church separated from during the Protestant Reformation?

full_context: Document 1: Protestantism: They formed, and identified with various religious groups advocating greater purity of worship and doctrine, as well as personal and group piety. Puritans adopted a Reformed theology, but they also took note of radical criticisms of Zwingli in Zurich and Calvin in Geneva. In church polity, some advocated for separation from all other Christians, in favor of autonomous gathered churches. These separatist and independent strands of Puritanism became prominent in the 1640s, when the supporters of a Presbyterian polity in the Westminster Assembly were unable to forge a new English national church.
Document 2: Catholic Church: The Catholic Church, also known as the Roman Catholic Church, is the largest Christian church, with more than 1.299 billion members worldwide. As one of the oldest religious institutions in the world, it has played a prominent role in the history and development of Western civilisation. The church is headed by the Bishop of Rome, who is known as the Pope. The church's doctrines are summarised in the Nicene Creed. Its central administration, the Holy See, is in the Vatican City, an enclave within Rome, Italy.
Document 3: Vatican City: Vatican City (/ ˈvætɪkən ˈsɪti / (listen); Italian: Città del Vaticano (tʃitˈta ddel vatiˈkaːno); Latin: Civitas Vaticana), officially Vatican City State or the State of Vatican City (Italian: Stato della Città del Vaticano; Latin: Status Civitatis Vaticanae), is a country located within the city of Rome. With an area of approximately 44 hectares (110 acres), and a population of 1,000, it is the smallest state in the world by both area and population. However, formally it is not sovereign, with sovereignty being held by the Holy See.
Document 4: Holy See: The Holy See (Italian: Santa Sede; Latin: Sancta Sedes; Ecclesiastical Latin: (ˈsaŋkta ˈsedes)), also called the See of Rome, is the ecclesiastical jurisdiction of the Catholic Church in Rome, the episcopal see of the Pope, and an independent sovereign entity. It serves as the central point of reference for the Catholic Church everywhere and the focal point of communion due to its position as the pre-eminent episcopal see of the universal church. Today, it is responsible for the governance of all Catholics, organised in their Particular Churches, Patriarchates and religious institutes.
Document 5: Protestantism: The success of the Counter-Reformation on the Continent and the growth of a Puritan party dedicated to further Protestant reform polarised the Elizabethan Age. The early Puritan movement was a movement for reform in the Church of England. The desire was for the Church of England to resemble more closely the Protestant churches of Europe, especially Geneva. The later Puritan movement, often referred to as dissenters and nonconformists, eventually led to the formation of various Reformed denominations.
Document 6: Protestantism: The Church of England declared its independence from the Catholic Church at the time of the Elizabethan Religious Settlement. Many of the new Anglican formularies of the mid-16th century corresponded closely to those of contemporary Reformed tradition. These reforms were understood by one of those most responsible for them, the then Archbishop of Canterbury Thomas Cranmer, as navigating a middle way between two of the emerging Protestant traditions, namely Lutheranism and Calvinism. By the end of the century, the retention in Anglicanism of many traditional liturgical forms and of the episcopate was already seen as unacceptable by those promoting the most developed Protestant principles.

Document 8: Pope Francis: Pope Francis (Latin: Franciscus; Italian: Francesco; Spanish: Francisco; born Jorge Mario Bergoglio; 17 December 1936) is the 266th and current Pope and sovereign of the Vatican City State. Francis is the first Jesuit pope, the first from the Americas, the first from the Southern Hemisphere, and the first pope from outside Europe since the Syrian Gregory III, who reigned in the 8th century.
Document 9: Baptists: During the Protestant Reformation, the Church of England (Anglicans) separated from the Roman Catholic Church. There were some Christians who were not content with the achievements of the mainstream Protestant Reformation. There also were Christians who were disappointed that the Church of England had not made corrections of what some considered to be errors and abuses. Of those most critical of the Church's direction, some chose to stay and try to make constructive changes from within the Anglican Church. They became known as "Puritans" and are described by Gourley as cousins of the English Separatists. Others decided they must leave the Church because of their dissatisfaction and became known as the Separatists.
Document 10: Catholic Church in the United States: The Catholic Church in the United States is part of the worldwide Catholic Church in communion with the Pope in Rome. With 70.4 million members, it is the largest religious denomination in the United States, comprising 22% of the population as of 2017. The United States has the fourth largest Catholic population in the world after Brazil, Mexico and the Philippines, the largest Catholic minority population, and the largest English - speaking Catholic population. The central leadership body of the Catholic Church in the United States is the U.S. Conference of Catholic Bishops.
Document 11: Plymouth Colony: The Pilgrims themselves were a part of the English Separatists (also known as English Dissenters) who were Protestant Christians who separated from the Church of England. The movement sought to practice Christianity as was done in the times of the Apostles. Following Martin Luther's and John Calvin's Reformation, they believed that the Bible was the only true source of religious teaching and that any additions made to Christianity had no place in Christian practice, especially with regard to church traditions, such as clerical vestments or the use of Latin in church services. In particular, they were strongly opposed to the Anglicans' episcopal form of church government. They believed that the church was a community of Christians who made a covenant with God and with one another. Their congregations had a democratic structure. Ministers, teachers, and lay church elders were elected by and responsible to the entire congregation (Calvinist Federalism). Each congregation was independent of all the others and directly subject to God's (or Christ's) government (theocracy), hence the name Congregationalism. The Pilgrims distinguished themselves from the Puritans in that they sought to ``separate ''themselves from the Anglican Church, rather than reform it from within. It was this desire to worship from outside of the Anglican Communion that led them first to the Netherlands and ultimately to New England.
Document 12: Protestantism: Protestantism is a form of Christian faith and practice which originated with the Protestant Reformation,[a] a movement against what its followers considered to be errors in the Roman Catholic Church. It is one of the three major divisions of Christendom, together with Roman Catholicism and Eastern Orthodoxy. Anglicanism is sometimes considered to be independent from Protestantism.[b] The term derives from the letter of protestation from Lutheran princes in 1529 against an edict condemning the teachings of Martin Luther as heretical.
Document 13: Protestantism: Contrary to how the Protestant Reformers were often characterized, the concept of a catholic or universal Church was not brushed aside during the Protestant Reformation. On the contrary, the visible unity of the catholic or universal church was seen by the Protestant reformers as an important and essential doctrine of the Reformation. The Magisterial reformers, such as Martin Luther, John Calvin, and Huldrych Zwingli, believed that they were reforming the Roman Catholic Church, which they viewed as having become corrupted. Each of them took very seriously the charges of schism and innovation, denying these charges and maintaining that it was the Roman Catholic Church that had left them. In order to justify their departure from the Roman Catholic Church, Protestants often posited a new argument, saying that there was no real visible Church with divine authority, only a spiritual, invisible, and hidden church—this notion began in the early days of the Protestant Reformation.
Document 14: Protestantism: The political separation of the Church of England from Rome under Henry VIII brought England alongside this broad Reformation movement. Reformers in the Church of England alternated between sympathies for ancient Catholic tradition and more Reformed principles, gradually developing into a tradition considered a middle way (via media) between the Roman Catholic and Protestant traditions. The English Reformation followed a particular course. The different character of the English Reformation came primarily from the fact that it was driven initially by the political necessities of Henry VIII. King Henry decided to remove the Church of England from the authority of Rome. In 1534, the Act of Supremacy recognized Henry as the only Supreme Head on earth of the Church of England. Between 1535 and 1540, under Thomas Cromwell, the policy known as the Dissolution of the Monasteries was put into effect. Following a brief Roman Catholic restoration during the reign of Mary I, a loose consensus developed during the reign of Elizabeth I. The Elizabethan Religious Settlement largely formed Anglicanism into a distinctive church tradition. The compromise was uneasy and was capable of veering between extreme Calvinism on the one hand and Roman Catholicism on the other. It was relatively successful until the Puritan Revolution or English Civil War in the 17th century.
Document 15: Christian: As of the early 21st century, Christianity has approximately 2.4 billion adherents. The faith represents about a third of the world's population and is the largest religion in the world. Christians have composed about 33 percent of the world's population for around 100 years. The largest Christian denomination is the Roman Catholic Church, with 1.17 billion adherents, representing half of all Christians.
