Tranquillitas ordinis is a Latin phrase meaning the 'tranquility of order' or 'well-ordered concord'. The term is associated with the Roman Catholic tradition of just war theory, and is found in the writings of Augustine of Hippo and Thomas Aquinas. Depending on the author and the context, the term is used to convey various meanings in theology and politics. These meanings include the divine order imposed on the universe and a theoretical framework for peace. Tranquillitas ordinis remains a cornerstone of Catholic teaching on peace. It is included in the framework laid out by Pope John XXIII in his 1963 encyclical, Pacem in terris, and is a featured topic at The Global Quest for Tranquillitas Ordinis, a conference organized by the Pontifical Academy of Social Sciences.^[1]
