Between 1378 and 1417, the Catholic Church split into distinct factions obeying simultaneous rivals for the papal throne, plunging medieval Europe into a profound spiritual crisis. What began as a disputed election in Rome escalated into a multi-decade spectacle featuring three competing popes, each condemning the others as impostors. This institutional fracture exposed the deep rot of political corruption within the Curia, undermined the moral authority of the papacy, and directly paved the way for the Protestant Reformation.
The roots of the crisis lay in the turbulent relocation of the papacy to Avignon, France, and its eventual return to Rome. When Pope Gregory XI died in 1378, Roman mobs surrounded the conclave, demanding a local pontiff to prevent another French-dominated reign. Fearing for their lives, the cardinals elected Urban VI, an abrasive Neapolitan reformer. Urban quickly alienated his electors with erratic behavior and threats against the College of Cardinals. Fleeing Rome, these cardinals declared the election void due to coercion and elected Clement VII, who promptly established a rival court back in Avignon. Europe fractured along political lines: England, the Holy Roman Empire, and northern Italy backed the Roman claimant, while France, Scotland, and Spanish kingdoms rallied behind Avignon.
How the Two-Pope Crisis Became Three
The dual papacy quickly calcified into a structural stalemate that neither side could win. Ordinary believers faced impossible spiritual dilemmas, unsure which sacraments were valid, where to send ecclesiastical taxes, or which pontiff held the legitimate keys to heaven. Towns and parishes split down the middle, and neighboring lords exploited the confusion to seize church lands.
Frustrated by decades of intransigence, a group of reform-minded cardinals and scholars convened the Council of Pisa in 1409. Their goal was straightforward: depose both Gregory XII (the Roman claimant) and Benedict XIII (the Avignon claimant) and elect a fresh, universally accepted pope.
Instead of solving the problem, the Council made it worse. Neither Gregory nor Benedict recognized the authority of the Council of Pisa or stepped down. The council elected Alexander V (soon succeeded by John XXIII), creating a chaotic three-way division.
- Rome Lineage: Gregory XII, backed by parts of Italy and Germany.
- Avignon Lineage: Benedict XIII, backed by Aragon and Scotland.
- Pisan Lineage: John XXIII, backed by France and Florence.
Europe now had three courts, three tax structures, and three separate chains of excommunication. The absurdity of the situation eroded public reverence for the office of the papacy. Secular monarchs stepped into the vacuum, extracting heavy concessions from whichever pope happened to need their military protection.
The Resolution at the Council of Constance
The three-way impasse dragged on until the Holy Roman Emperor Sigismund forced a reckoning. He pressured John XXIII to summon a new general council on neutral soil in the German city of Constance. The Council of Constance met from 1414 to 1418 with a sweeping mandate to heal the schism, eradicate heresy, and reform the Church.
To break the deadlock, the council adopted a radical legal doctrine known as Haec Sancta, which asserted that a general council derived its authority directly from Christ and held supreme power over the Church—even superseding the pope. Armed with this revolutionary theory, the council dismantled the competing claims through distinct legal maneuvers:
- John XXIII Fled and Was Deposed: Realizing the council intended to strip all three men of power, John XXIII fled in disguise, but he was captured, put on trial for numerous financial and moral scandals, and deposed in 1415.
- Gregory XII Resigned Voluntarily: Recognizing the existential threat to the institution, the aging Roman claimant agreed to officially resign, giving the council legitimate legal standing to proceed.
- Benedict XIII Was Deposed in Absentia: Holed up in a coastal fortress in Peñíscola, Spain, Benedict stubbornly refused to yield. The council formally deposed him in 1417, though he maintained his defiant stance to his dying day, supported by a tiny remnant of followers.
With the slate cleared, the council elected Cardinal Oddone Colonna as Pope Martin V in November 1417, finally restoring a single, universally recognized head to Western Christendom.
The Long-Term Fallout on European Authority
While Martin V restored administrative unity, the institutional damage proved permanent. The methods used to end the schism unleashed forces that the papacy could never stuff back into the box.
First, conciliarism permanently weakened the absolute monarchy of the pope. Monarchs and regional bishops realized that a council could check papal overreach. Although later popes fought aggressively to reassert their absolute supremacy, the psychological barrier had broken.
Second, the financial exploitation required to sustain three parallel papal courts embittered the European populace. Simony—the selling of church offices—and the aggressive marketing of indulgences reached a fever pitch during these decades.
Finally, the crisis inspired grassroots theological dissent that anticipated the 16th-century Reformation. In Bohemia, scholar Jan Hus seized upon the spectacle of corrupt, competing popes to argue that the true head of the Church was Christ, not a morally bankrupt pontiff. Though Hus was burned at the stake for heresy at the Council of Constance, his followers launched the Hussite Wars, proving that the fracture of European faith could no longer be patched over with mere legal decrees.
Frequently Asked Questions
Why did the cardinals elect two popes in 1378?
The cardinals elected Urban VI under intense pressure from an angry Roman mob that wanted an Italian pope. Shortly after, Urban's erratic, hostile treatment of the cardinals led them to claim the election was coerced and therefore invalid, prompting them to elect a second pope.
Did ordinary people know there were multiple popes?
Yes. The schism affected daily life through competing tax collectors, conflicting excommunications, and rival preachers. Communities often split based on regional political alliances.
How did the Western Schism differ from the Great Schism of 1054?
The 1054 Great Schism was a theological and cultural split between the Western (Latin) Church and the Eastern (Greek) Orthodox Church. The Western Schism (1378–1417) was an internal crisis entirely within the Western Catholic Church over who was the rightful pope.
What role did secular rulers play in prolonging the schism?
European kings and princes used the rival popes as political leverage. They switched their allegiance or granted protection to whichever pontiff offered them the greatest tax exemptions, territorial concessions, or military support.
