History is life's teacher says Pope Francis
“Nothing is lost with peace. Everything can be lost with war,” Pope Francis told members of the Pontifical Committee of Historical Sciences repeating the phrase first used by Pope Pius XII in 1939. The Pontifical Committee of Historical Sciences, established by Pope Pius XII in 1954, promotes the development of the historical sciences through international cooperation. It continues the work of the Commission of Cardinals for Historical Studies, founded in 1883 by Pope Leo XIII.
