A century ago a new line appeared on the map of Ireland. It carved its way for 300 miles across the landscape from Derry in the North West to Dundalk in the East. Partition separated farmers from their land, businesses from their customers, and children from their schools. Streams and rivers, bóithre, country roads, fields became the boundary for this new border. The front door of a home was suddenly in a different state. Towns were cut off from their natural economic and social hinterlands. Communities were divided and separated. Partition was imposed at gunpoint by the British Government.
