Council of Trent
19th Ecumenical Council of the Catholic Church
The Council of Trent (Latin: Concilium Tridentinum), held between 1545 and 1563 in Trent (or Trento), in Northern Italy, was the 19th ecumenical council of the Catholic Church. Prompted by the Protestant Reformation at the time, it has been described as the "most impressive embodiment of the ideals of the Counter-Reformation." It was the last time a Catholic ecumenical council was organized outside the city of Rome, and the second time a council was convened in the territory of the Holy Roman Empire (the first being the Council of Constance).
The Council issued key statements and clarifications of the Church's doctrine and teachings, including scripture, the biblical canon, sacred tradition, original sin, justification, salvation, the sacraments, the Mass, and the veneration of saints and also issued condemnations of what it defined to be heresies committed by proponents of Protestantism. The consequences of the council were also significant with regard to the Church's liturgy and censorship.
The Council met for twenty-five sessions between 13 December 1545 and 4 December 1563. Pope Paul III, who convoked the council, oversaw the first eight sessions (1545–1547), while the twelfth to sixteenth sessions (1551–52) were overseen by Pope Julius III and the seventeenth to twenty-fifth sessions (1562–63) by Pope Pius IV. More than three hundred years passed until the next ecumenical council, the First Vatican Council, was convened in 1869.
Background information
Obstacles and events before the Council's problem area
On 15 March 1517, the Fifth Council of the Lateran closed its activities with a number of reform proposals (on the selection of bishops, taxation, censorship and preaching) but not on the new major problems that confronted the Church in Germany and other parts of Europe. A few months later, on 31 October 1517, Martin Luther issued his 95 Theses in Wittenberg.
A general, free council in Germany
Luther's position on ecumenical councils shifted over time, but in 1520 he appealed to the German princes to oppose the papal Church at the time, if necessary with a council in Germany, open and free of the Papacy. After the Pope condemned in Exsurge Domine fifty-two of Luther's theses as heresy, German opinion considered a council the best method to reconcile existing differences.

Why this record matters

The strongest evidence will usually combine a dated visual record with documents produced by the authority responsible for the place. The source revision retrieved here is dated Jul 30, 2026. The linked authority identifier is Q172991. VIAF identifies the subject as 146803075. The Library of Congress control number is n79144782. 1 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1545, 1563, 1547 and 1551.
Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
