Pacem in terris (lit. 'Peace on Earth') was a papal encyclical issued by Pope John XXIII on 11 April 1963 on the rights and obligations of individuals and of the state, as well as the proper relations between states. It emphasized human dignity and equality among all people, and made mention of issues such as the rights of women, nuclear non-proliferation, and the United Nations, all of which it endorsed. It was the last encyclical drafted by John XXIII, who had been diagnosed with cancer in September 1962 and died two months after the encyclical's completion. Biographer Peter Hebblethwaite called it Pope John's "last will and testament". Published on Holy Thursday, the Pope called it his "Easter gift".
