This is a list of numbered Regiments of Foot of the British Army. Previously regiments were formed only for a given campaign or war and usually named after their colonel. Later they were numbered according to their seniority in the line of battle. At this time the numbers generally fell into disuse. With modifications the numbers existed until 1881, when the concept of 'County' regiments was formalised ( i.e. the regiment would be associated with and recruit from a given country or region ).
