As the clock struck noon on Monday, 11 July 1921, a truce came into force which effectively ended the Irish War of Independence.
The conflict spanned two-and-a-half years and cost more than 2,000 lives.
The ceasefire was agreed three days earlier between the British government and Irish republican leaders - leaders who would soon form their own state on the southern side of the new border.
In Belfast, the final hours leading up to the truce were marred by bloodshed.
