The Edict of Torda (, , ) was a decree that authorized local communities to freely elect their preachers in the Eastern Hungarian Kingdom of John Sigismund Zápolya. The delegates of the Three Nations of Transylvaniathe Hungarian nobles, Transylvanian Saxons, and Székelysadopted it at the request of the monarch's Antitrinitarian court preacher, Ferenc Dávid, in Torda (, ) on 28January 1568. Though it did not acknowledge an individual's right to religious freedom, in sanctioning the existence of a radical Christian religion in a European state, the decree was an unprecedented act of religious tolerance.

The Catholic and Eastern Orthodox churches had coexisted in the southern and eastern territories of the medieval Kingdom of Hungary for centuries. However, ideas that the Catholic Church regarded as heresy were not tolerated: the Hungarian Hussites were expelled from the country in the 1430s and the 1523 Diet of Hungary passed a decree that ordered the persecution of Lutherans. The latter decree was in practice ignored during the civil war that followed the Ottoman victory against the Hungarian army in the Battle of Mohács in 1526. After the Ottomans occupied the central regions of the medieval kingdom in 1541, they allowed the infant John Sigismund to rule the lands to the east of the river Tisza under the regency of his mother, Isabella Jagiellon. In the early 1540s the Diets acknowledged the right of the Three Nations to freely regulate their internal affairs. The Saxons regarded religion as an internal affair and ordered the introduction of the Lutheran Reformation in their settlements in 1544–1545. The Diet sanctioned the coexistence of the Catholic and Lutheran denominations only in 1557.

John Sigismund started to rule personally after his mother died in 1559. He was interested in religious affairs and organized a series of debates between the representatives of the different Protestant theologies. He converted from Catholicism to Lutheranism in 1562, and from Lutheranism to Calvinism in 1564. His court physician, Giorgio Biandrata, and Ferenc Dávid jointly persuaded him to also allow the public discussion of the doctrine of the Trinity. Sigismund accepted Dávid and Biandrata's Antitrinitarian views in 1567. The Edict of Torda was adopted at the following Diet. It stated that "faith is the gift of God" and prohibited the persecution of individuals on religious grounds. In practice, the edict only sanctioned the existence of four "received" denominationsthe Catholic, Lutheran, Calvinist, and Unitarian Churches. Further religious innovations were prohibited during the reign of John Sigismund's successor, Stephen Báthory, but religious tolerance remained a distinguishing feature of the Principality of Transylvania (the successor state to John Sigismund's realm) in Early modern Europe.

Background

The Catholic Church was facing a profound crisis in the Kingdom of Hungary at the end of the Middle Ages. Ideas that the Catholic Church regarded as heretical appeared in the late 14thcentury, primarily in the small towns. In the 1430s, young burghers who had studied at the University of Prague began teaching the theology of the Czech Jan Hus, despite his having been condemned to death for heresy at the Council of Constance. Two Hussite preachers completed the first Hungarian translation of the Bible in the early 1430s. Pope Eugene IV appointed the Franciscan James of the Marches to eradicate Hussitism in Hungary in 1436. The Hussites who survived the purge fled to Moldavia in 1439.

German burghers of Upper Hungary (now mostly in Slovakia) were the first to adopt Martin Luther's views in the early 1520s. Dozens of the German courtiers of Mary of Habsburg (the wife of Louis II of Hungary) also supported the ideas of the Reformation. However, the Hungarian noblemen remained hostile towards Lutheran theology, primarily because they wanted to secure the support of the Holy See against the Ottoman Empire. On 24April 1523, the Diet of Hungary passed a decree that ordered the persecution and execution of Luther's followers in the entire kingdom.

The Ottoman Sultan Suleiman the Magnificent annihilated the Hungarian army in the Battle of Mohács in 1526. LouisII drowned in a nearby stream while fleeing from the battlefield. The majority of the Hungarian noblemen elected as king one of their number, John Zápolya, but the most powerful noblemen proclaimed LouisII's brother-in-law, Ferdinand of Habsburg, the lawful monarch, leading to a civil war that lasted nearly two decades.

Ferdinand and John reached a compromise in 1538. Each acknowledged the other's right to rule, but they also agreed that the kingdom was to be reunited under the rule of the one who survived the other. However, the childless John married Isabella Jagiellon, who gave birth to a son, John Sigismund, in 1540. Two weeks later, John died, but only after persuading his supporters to pledge that they would secure his infant son's rule. Keeping their word, they elected John Sigismund king in Buda in clear contradiction to the 1538 compromise. The royal election provoked a new invasion by Ferdinand's troops.

Taking advantage of the new conflict, Suleiman again invaded Hungary in 1541. He occupied the central region, but confirmed John Sigismund's rule in the lands to the east of the river Tisza as his vassal, creating an Eastern Hungarian Kingdom. The Estates of John Sigismund's realm acknowledged the situation and swore fealty to the child king and his mother.

Towards tolerance

The Kingdom of Hungary, especially its eastern territory, had been a borderland between the Catholic and Eastern Orthodox churches. The two churches co-existed without major conflicts, although the monarchs occasionally took (mostly marginal) measures against Eastern Orthodox believers in the 14thcentury. Eastern Orthodox lords established Basilite monasteries in the southern and northeastern regions; Eastern Orthodox bishops residing in Transylvanian monasteries were documented from the late 14thcentury.

The civil war that followed the Battle of Mohács made the enforcement of anti-Lutheran legislation difficult after 1526. The popular interpretation of the Ottomans' victory at Mohács as a sign of the wrath of God facilitated the spread of the ideas of the Reformation. John Zápolya became especially reluctant to persecute the Lutherans after the Pope excommunicated him for his alliance with the Ottomans in 1529. He organized a public debate between Catholic prelates and a Lutheran preacher in Schässburg (, ) in 1538.

Between 1541 and 1545, the Diets (or legislative assemblies) in the eastern Hungarian Kingdom re-affirmed the agreement that the Hungarian noblemen, Transylvanian Saxons, and Székelys had signed during the Transylvanian peasant revolt in 1437, making this "Union of the Three Nations" a fundamental law. The Diets decreed that each nation could freely regulate its internal affairs at its own assemblies. The Saxons regarded religious issues as an internal affair, and their general assembly ordered the introduction of the Reformation in their towns and villages in 1544–1545. Lutheran ideas also spread among the noblemen from the 1540s. Twenty-nine Hungarian preachers from the region of Várad (, ) adopted a creed similar to the Augsburg Confession at their synod in Erdőd (, ) in 1545.

The Ottoman authorities always acknowledged the co-existence of multiple monotheist religions in line with Islamic traditions, although Christians and Jews were obliged to pay a special tax, known as jizya, in the Ottoman Empire. In 1548 the Ottoman pasha (or governor) of Buda forbade the Catholic authorities of Tolna to persecute the local Lutheran preacher, stating that all locals "should be able to listen to and receive the word of God without any danger". Historian Susan J. Ritchie says that the pasha's order may have influenced the Edict of Torda, although "no direct evidence exists" that the compilers of the edict knew of the order.

Isabella was forced to surrender her son's realm to Ferdinand of Habsburg in 1551. In the same year, the Lutheran members of the town council of Debrecen accused the town pastor, Márton Kálmáncsehi, of heresy because he denied the real presence of Christ in the Eucharist. He was forced to flee from the town, but the wealthy Péter Petrovics put him under his protection.

After Ferdinand of Habsburg proved unable to secure the defence of the eastern territories, the Diet persuaded Isabella and John Sigismund to return in 1556. Petrovics, who had always been their principal supporter, soon initiated new religious debates between Lutheran and Calvinist clergymen. In 1557 the Diet passed a decree that historian Krista Zach describes as "the founding document of the so-called religious tolerance" in John Sigismund's realm. Actually, the decree only acknowledged the existence of a separate Lutheran Church, urging the Catholic and Lutheran believers to avoid violent acts against each other. In the same year, Hungarian clerics of the region of Várad confirmed their adherence to the Calvinist view of the Eucharist, for which the Lutherans labelled them "Sacramentarians". The following Diet confirmed the decree that had been passed in 1557, but it also outlawed the Sacramentarians in 1558.

John Sigismund, Dávid and Biandrata

John Sigismund became the actual ruler of the Eastern Hungarian Kingdom after the death of his mother on 15November 1559. He had grown up as a Catholic, but he was curious about theological issues. He organized new religious debates between representatives of the Lutheran and Calvinist theologies in Mediasch (, ) in January 1560 and February 1561. His Lutheran chancellor, Mihály Csáky, persuaded him to order the two parties to summarize their views in writing. The summaries were sent for review to Wittenberg, Leipzig, and two other centers of theological studies in the Holy Roman Empire. The four German academies responded in early 1562, and their opinions were taken into account when the synod of the Lutheran clergy adopted a new creed in the same year. John Sigismund soon converted from Catholicism to Lutheranism.

A clergyman from Kolozsvár (, ), Ferenc Dávid, had meanwhile become a key figure in the development of Protestant ideas in John Sigismund's realm. Historian István Keul says Dávid's career displays his extraordinary "denominational flexibility". He was elected the superintendent of the Church of the Hungarian Lutherans in 1557. He made attempts to reconcile the Lutheran and Calvinist clerics, but their views of the Eucharist were incompatible. Dávid's studies of the works of Erasmus of Rotterdam and Michael Servetus contributed to his critical attitude towards dogmas and the development of his conviction of the free choice of religion.

In the early 16th century Erasmus had urged commoners to regularly read the Bible. While producing his own critical edition of the Bible, Erasmus realized the Johannine comma, a brief aside which had previously been regarded as the principal evidence for the doctrine of the Trinity, did not exist in any of the oldest Greek manuscripts of the Bible, meaning it had been inserted later by scribes. Servetus read the critical studies of Joseph Kimhi and other Jewish scholars about the Trinity, and concluded that this dogma was the principal doctrine that separated Christianity from Judaism and Islam. He was forced to leave his native Spain for his Antitrinitarian views. He was executed with John Calvin's consent in Geneva in 1553.
