Great Western Schism

Great Western Schism The Great Western Schism was a protracted crisis of papal rivalries and competing claims to the papal throne from 1378 to 1417 that divided Western Christianity and involved rival courts in Avignon, Rome, and later Pisa. It entwined ecclesiastical disputes with dynastic and diplomatic conflicts among France, England, the Holy Roman Empire, the Kingdom of Aragon, and Italian city-states such as Florence, Venice, and Milan. The schism energised movements for church reform associated with figures like Jan Hus, John Wycliffe, and institutions such as the University of Paris and the Council of Constance. It concluded with decisions at the Council of Constance that reshaped relations among the papacy, ecclesiastical councils, and European monarchies.

Background and Causes

The crisis had roots in the Avignon Papacy, where successive pontificates established a curia closely allied with the French Crown and administered from Avignon after the papal court moved from Rome under Pope Clement V. Tensions between Roman civic factions in Rome and French influence intersected with the aftermath of the Black Death, which affected clerical staffing and fiscal practices under papal administrators like Pope John XXII and Pope Benedict XII. The return of the curia to Rome under Pope Gregory XI and his death precipitated contested conclaves involving Roman civic leaders of the Colonna family and the Orsini family, foreign cardinals aligned with King Charles V of France and cardinals sympathetic to the Kingdom of Naples. Controversies over nepotism, ecclesiastical taxation, and the papacy’s legal authority as articulated by jurists at the University of Bologna and advocates in the Avignon chancery exacerbated factionalism.

Major Phases and Key Figures

The first phase began with the election of Urban VI in 1378, whose abrasive reforms alienated the College of Cardinals and led to the election of an alternative pope, Clement VII, establishing the Avignon line supported by Charles V of France and the French crown. The second phase featured lengthy contests between Roman popes such as Boniface IX, Innocent VII, and Gregory XII and Avignon claimants like Benedict XIII (Avignon) and Clement VIII (Avignon). The Pisan Council of 1409, convened by dissident cardinals including Pietro Philarghi and Pietro Filargo (later Alexander V), produced a third line of claimants, complicating allegiances among monarchs including Henry IV of England, Charles VI of France, Ferdinand I of Aragon, and Sigismund, Holy Roman Emperor. Reformist theologians such as Marsilius of Padua and William of Ockham provided intellectual background to challenges, while figures like Paolo da Concina and Cardinal Albergati played diplomatic roles. The Council of Constance brought leaders such as Pope Martin V and emperor-elect Sigismund of Luxembourg to prominence.

Political and Ecclesiastical Consequences

The schism reshaped diplomatic relations among France, England, the Crown of Aragon, the Kingdom of Naples, and the Holy Roman Empire, as monarchs used papal allegiance for geopolitical advantage. Ecclesiastically, the crisis undermined papal prestige and bolstered doctrines of conciliarism promoted by theologians at the University of Paris and practiced at the Council of Constance and earlier at the Council of Pisa. Juridical questions engaged scholars from University of Padua, University of Bologna, and clerks trained in the papal chancery, influencing later developments in canon law codified under Pope Martin V and legal thinkers like Bartolus de Saxoferrato. The schism catalysed reform movements that intersected with proto-Reformation figures such as John Hus and reforming impulses in monastic houses like Cluny and Basilian communities.

Attempts at Resolution and Councils

Multiple solutions were attempted: negotiation among cardinals, pressure from secular rulers including Charles VI of France and Henry III of Castile, and ecclesiastical conciliarism. The Council of Pisa (1409) aimed to end the division by deposing both lines and electing Alexander V, but instead created a tripartite claim. The decisive settlement occurred at the Council of Constance (1414–1418), convened through the initiative of Sigismund, Holy Roman Emperor and attended by delegates from the Holy Roman Empire, Kingdom of England, Kingdom of France, and Italian communes such as Florence and Venice. The council deposed or received resignations from John XXIII (antipope) and Benedict XIII (Avignon) and secured the resignation of Gregory XII through negotiated guarantees, culminating in the election of Martin V and broad acceptance by European powers.

Legacy and Historiography

The schism’s legacy includes the strengthening of conciliar theory debated by jurists and theologians at the University of Paris and later contested by papal restorations under Pope Pius II and Pope Leo X. Historiography has evolved from contemporaries such as Froissart and Niccolò Machiavelli to modern scholars in the traditions of A. H. Lloyd and Walter Ullmann, examining sources from papal registers in Avignon and Roman archives in the Vatican Library. The crisis is interpreted variously as a clash of political sovereignties, a constitutional moment for Western Christendom, and a precursor to the Reformation; it influenced later concordats like the Concordat of Bologna and contributed to institutional reforms affecting the College of Cardinals and papal electoral law reconceived in later pontificates.
