What happened
Pope Paul III convened the Council of Trent in 1545 to formulate the Catholic Church's response to Protestant theology and to reform internal abuses. Meeting across 25 sessions with long gaps between them until it closed in December 1563, the council reaffirmed transubstantiation, declaring that the Eucharist truly and substantially contains the body and blood of Christ, and rejected the Protestant doctrine of salvation by faith alone, holding instead that a believer is saved by faith together with the good works it inspires. The council also formally settled which books belonged in the biblical canon and affirmed the Latin Vulgate as the Church's authoritative scriptural text, and it mandated that every diocese establish seminaries to properly educate its clergy.
Why it matters
Trent's decrees became the doctrinal blueprint for the Counter-Reformation, giving the Catholic Church clear, codified answers to Protestant challenges and a program of institutional reform, including better-trained priests and more consistent preaching, that helped Catholicism recover ground and hold onto contested territory in southern and central Europe over the following century.
How we know
The council's own decrees and canons survive as an official published record, still cited by Catholic theology today; the World History Encyclopedia's article on Trent documents both the doctrinal content and the eighteen-year span of sessions.
