The plague of 664 was an epidemic that affected the British Isles in 664 AD, during the first plague pandemic. It was the first recorded epidemic in English history, and coincided with a solar eclipse.[1] It was referred to by later sources as "The Yellow Plague of 664"[This quote needs a citation] and said to have lasted for twenty or twenty-five years, causing widespread mortality, social disruption and abandonment of religious faith. The disease responsible was probably Plague - part of the First Plague Pandemic - or else smallpox.[1]
