Christian Left was part of the Unidad Popular coalition, and declared itself to be a revolutionary party of Christian and Humanist tradition, and in favour of constructing socialism. It tended to agree with the radical wing of the Unidad Popular (the leftist majority of the Socialist Party and parts of the MAPU). After the 1973 coup, the party members were subject to arrest and torture, like people from other leftist groups. The party's militants continued operating together with and within left-wing groups. After democracy was restored in Chile in 1990, most of the militants joined the Socialist Party while others continued as the Christian Left party.
