What is the Society of St Pius X and its excommunication by Pope Leo

The Vatican has officially declared the Society of St Pius X (SSPX) in schism after the group consecrated four bishops without papal approval, defying Pope Leo XIV. This act has led to the excommunication of the bishops and those who support the SSPX, and their sacraments are now deemed illicit. The SSPX, founded in 1970 in opposition to reforms from the Second Vatican Council, continues to operate independently, rejecting modernizing changes in the Church.
