which nation was the first to accept christianity
Armenians Most Armenians adhere to the Armenian Apostolic Church, a non-Chalcedonian church, which is also the world's oldest national church. Christianity began to spread in Armenia soon after Jesus' death, due to the efforts of two of his apostles, St. Thaddeus and St. Bartholomew.[28] In the early 4th century, the Kingdom of Armenia became the first state to adopt Christianity as a state religion.[29]
Anglo-Saxon Christianity Christianisation of the Anglo-Saxon Kingdoms began in AD 597, influenced by Celtic Christianity from the north-west and by the Roman church from the south-east, gradually replacing Anglo-Saxon polytheism which had been introduced to what is now England over the course of the 5th and 6th centuries with the arrival of the Anglo-Saxons. The first Archbishop of Canterbury, Augustine took office in 597 AD. In 601, he baptized the first Christian Anglo-Saxon king, Æthelberht of Kent. The last pagan Anglo-Saxon/Jutish king, Arwald, died in 686.
