Kirklees is a metropolitan borough of West Yorkshire, England. The borough compromises of the eight towns of Batley, Birstall, Cleckheaton, Dewsbury, Heckmondwike, Holmfirth, Huddersfield, Mirfield and Slaithwaite. It is governed by Kirklees Council. Kirklees had a population of 422,500 in 2011; it is the third largest metropolitan district in England by area size, behind Doncaster and Leeds.
The borough was formed on 1 April 1974 by the provisions of the Local Government Act 1972 as part of a reform of local government in England. Eleven former local government districts were merged: the county boroughs of Huddersfield and Dewsbury, the municipal boroughs of Batley and Spenborough and the urban districts of Colne Valley, Denby Dale, Heckmondwike, Holmfirth, Kirkburton, Meltham and Mirfield.
The name Kirklees was chosen by the merging councils from more than fifty suggestions, including Upper Agbrigg, Brigantia and Wooldale. It was named after Kirklees Priory, which is claimed to be site of Robin Hood's death, situated midway between Huddersfield and Dewsbury. The priory was located within the present-day Kirklees Park estate, most of which actually lies in the neighbouring borough of Calderdale.
Under the original draft of the Act, the district would have included Ossett, part of the Dewsbury Parliamentary constituency at that time. It was eventually decided that Ossett was too remote to be governed from Huddersfield and the town was included within the Wakefield district instead.
Kirklees sits in quite a central position to all the other surrounding unitary boroughs of West Yorkshire, with people living in the northern parts commuting to Leeds and York for work and education. People living in the western parts commute to Bradford, Halifax and Huddersfield for education and work. People living in the southern and eastern parts commute to Wakefield, Barnsley, Sheffield and Manchester for work and education. The largest towns and principal districts in the borough are Huddersfield, Dewsbury, Batley, Heckmondwike and Cleckheaton.
