Archaeological research indicates that Glastieve was near to an established town that traded with Europe as early as 250 BCE. From around 55 CE, the area was controlled by the Roman Empire and was possibly inhabited by the Dumnonii. From around 600 CE to 2017 CE the land was controlled by the Kingdom of England, the Kingdom of Great Britain and the United Kingdom as farmland part of the nearby city of Exeter. In February 2017, an independence movement (called the Glastieve Planning Board) created a Cabinet and a deceleration of independence that was read out on the 23rd February to a meeting of the government, which at the time consisted of eight individuals.
