On 6 January 1649, the English Rump Parliament took the momentous decision to place King Charles I on trial, accusing him of treason and various "high crimes."
This unprecedented move followed years of civil war between the monarchy and Parliament, with Charles's perceived autocratic rule and disregard for Parliamentary authority at the heart of the conflict.
The trial marked a historic shift in the balance of power, as Parliament sought to hold the monarch accountable, fundamentally challenging the divine right of kings.
