Bootle (pronounced ) is a town in the Metropolitan Borough of Sefton, Merseyside, England, which had a population of 51,394 in 2011; the wider Parliamentary constituency had a population of 98,449. Historically part of Lancashire, Bootle's proximity to the Irish Sea and the industrial city of Liverpool to the south saw it grow rapidly in the 1800s, first as a dormitory town for wealthy merchants, and then as a centre of commerce and industry in its own right following the arrival of the railway and the expansion of the docks and shipping industries. The subsequent population increase was fuelled heavily by Irish migration. The town was heavily damaged in World War II with air raids against the port and other industrial targets. Post-war economic success in the 1950s and 1960s gave way to a downturn, precipitated by a reduction in the significance of Liverpool Docks internationally, and changing levels of industrialisation, coupled with the development of modern suburbs and the expansion of industries into the Merseyside hinterlands. By the 1980s, there had been a sharp spike in unemployment and population decline. Large-scale renewal projects have begun to help regenerate the local economy.

Resort Bootle was originally a small hamlet built near the 'sand hills' or dunes of the river estuary. In the early 19th century, it began to develop as a bathing resort, attracting wealthy people from Liverpool. Some remaining large villas which housed well-to-do commuters to Liverpool are located in the area known locally as 'Bootle Village'. Development The Liverpool, Crosby and Southport Railway arrived in the 1840s and Bootle experienced rapid growth. By the end of the 19th century the docks had been constructed along the whole of the river front as far as Seaforth Sands to the north. The town became heavily industrialised. Bootle was incorporated as a municipal borough in 1868 under the Municipal Corporations Act 1835, and in 1889 was granted the status of a county borough by the Local Government Act 1888, becoming independent from the administrative county of Lancashire. During this time period it was
