Vatican II, or the Second Vatican Council, was an ecumenical council of the Roman Catholic Church that took place from 1962 to 1965. Convened by Pope John XXIII, the council aimed to address relations between the Catholic Church and the modern world, promoting renewal and reform within the Church. The council produced several important documents that emphasized the role of the laity, the importance of interfaith dialogue, and the need for the Church to engage with contemporary society. Key outcomes included changes in the liturgy, increased participation of the faithful, and a more open approach to other religions.
