What is 536 ad?
Key facts
536 AD is a year in the AD/CE dating system, best known for a volcanic winter that caused darkened skies, crop failures, and famine across the Northern Hemisphere [2].
Context
536 AD is a year in the AD/CE system, but in history it is especially known for a volcanic winter linked to an eruption in early 536 or late 535 [2]. The event caused darkened skies, crop failures, and famine across the Northern Hemisphere [2]. It is described as one of the most severe cooling episodes in the last two thousand years [2]. Cambridge notes that a vast ash cloud made "the sun become dark" [1]. Two further eruptions in 540 and 547 began unprecedented cooling [1]. The event is linked to the Late Antique Little Ice Age, lasting from 536 to 660 [2].
