Rafael Luigi Pecci

Rafael Luigi Pecci, known as Pope Leo XIII, served as the head of the Catholic Church from 1878 to 1903. He is notable for his significant contributions to Catholic social teaching, particularly through his encyclical 'Rerum Novarum,' which addressed the rights of workers and the responsibilities of employers. His papacy marked a pivotal moment in the Church's engagement with modern society, advocating for social justice and the importance of addressing the needs of the poor. Leo XIII's legacy continues to influence Catholic thought on social issues today.
