The line was drawn in the early 1920s, dividing the newly independent Republic of Ireland from the six counties of Northern Ireland, which remained part of the United Kingdom. Ireland’s customs controls sharply reduced trade between the two.
The boundary took on increased significance during the decades of the Troubles, the sectarian conflict in Northern Ireland that left some 3,600 dead.
In the 1990s, with the adoption of the European Single Market resolving trade issues and the signing of the Good Friday Agreement putting an end to the bloodshed, the border became all but invisible.
Now, as Britain — and, by extension, Northern Ireland — prepares to leave the European Union, leaders are working to avoid reinstating border controls that might renew violence.
