Deposed Ecumenical Patriarch of Constantinople Nestorius, considered the originator of Nestorianism, is exiled by Roman Emperor Theodosius II to a monastery in Egypt.
Nestorius, the former Patriarch of Constantinople and founder of Nestorianism, is exiled by Emperor Theodosius II to a monastery in Egypt.
In 435 AD, Emperor Theodosius II ordered the exile of Nestorius to Egypt, ending his controversial tenure as Patriarch of Constantinople.
Nestorius's teachings had sparked fierce debates over the nature of Christ, leading to charges of heresy at the Council of Ephesus.
His exile to a remote monastery in the Egyptian desert was intended to silence his influence on the Eastern Church.
Despite imperial edict, Nestorian communities continued to flourish in Persia and beyond, shaping Christian theology across Asia.
The incident highlighted the deep intertwining of theological disputes and imperial politics.
It also marked a pivotal moment in the enduring schism between Eastern and Western branches of Christianity.

Whittaker Chambers accuses Alger Hiss of being a communist and a spy for the Soviet Union.
Whittaker Chambers publicly accused Alger Hiss of being a Soviet spy on August 3, 1948.
On August 3, 1948, former communist Whittaker Chambers leveled a stunning accusation against State Department official Alger Hiss, alleging he had acted as a Soviet spy during the 1930s. The nationwide broadcast of Chambers’ testimony intensified fears of communist infiltration at the dawn of the Cold War. Hiss, a respected diplomat and former aide to Secretary of State Cordell Hull, vehemently denied the charges. The ensuing controversy led to high-profile congressional hearings and a perjury trial that would captivate the American public. Although Hiss was never convicted of espionage, he was found guilty of perjury in 1950 and imprisoned. The case fueled Senator Joseph McCarthy’s anti-communist crusade and influenced U.S. domestic policy for years to come. It remains a landmark episode in America’s postwar political landscape.
