beliefs existed among Unitarians in each of these regions, they initially grew independently from each other. Only later did they influence one another and accumulate more similarities. The Ecclesia minor or Minor Reformed Church of Poland, better known today as the Polish Brethren, was born as the result of a controversy that started on January 22, 1556, when Piotr of Goniądz (Peter Gonesius), a Polish student, spoke out against the doctrine of the Trinity during the general synod of the Reformed (Calvinist) churches of Poland held in the village of Secemin. After nine years of debate, in 1565, the anti-Trinitarians were excluded from the existing synod of the Polish Reformed Church (henceforth the Ecclesia maior) and they began to hold their own synods as the Ecclesia minor. Though frequently called "Arians" by those on the outside, the views of Fausto Sozzini (Faustus Socinus) became the standard in the church, and these doctrines were quite removed from Arianism. So important was Socinus to the formulation of their beliefs that those outside Poland usually referred to them as Socinians. The Polish Brethren were disbanded in 1658 by the Sejm (Polish Parliament). They were ordered to convert to Roman Catholicism or leave Poland. Most of them went to Transylvania or Holland, where they embraced the name "Unitarian". Between 1665 and 1668 a grandson of Socinus, Andrzej Wiszowaty Sr., published Bibliotheca Fratrum Polonorum quos Unitarios vocant (Library of the Polish Brethren who are called Unitarians 4 vols. 1665–1669). The Unitarian Church in Transylvania was first recognized by the Edict of Torda, issued by the Transylvanian Diet under Prince John II Sigismund Zápolya (January 1568), and was first led by Ferenc Dávid (a former Calvinist bishop, who had begun preaching the new doctrine in 1566). The term "Unitarian" first appeared as unitaria religio in a document of the Diet of Lécfalva, Transylvania, on 25 October 1600, though it was not widely used in Transylvania until 1638, when the formal recepta Unitaria Religio was published. The word Unitarian had been circulating in private letters in England, in reference to imported copies of such publications as the Library of the Polish Brethren who are called Unitarians (1665). Henry Hedworth was the first to use the word "Unitarian" in print in English (1673), and the word first appears in a title in Stephen Nye's A brief history of the Unitarians, called also Socinians (1687). The movement gained popularity
