Warrington (ˈwɒrɪŋtən) is an industrial town in the borough of the same name in Cheshire, England. The town sits on the banks of the River Mersey and until 1974, was part of Lancashire. It is east of Liverpool, and west of Manchester.
The population in 2019 was estimated at 165,456 for the town's urban area, and 210,014 for the wider borough, the latter being more than double that of 1968 when it became a new town. Warrington is the largest town in the ceremonial county of Cheshire. In 2011 the unparished area had a total population of 58,871.
Warrington was founded by the Romans at an important crossing place on the River Mersey. A new settlement was established by the Saxon Wærings. By the Middle Ages, Warrington had emerged as a market town at the lowest bridging point of the river. A local tradition of textile and tool production dates from this time.
The expansion and urbanisation of Warrington coincided with the Industrial Revolution, particularly after the Mersey was made navigable in the 18th century. The West Coast Main Line runs north to south through the town, and the Liverpool to Manchester railway (the Cheshire Lines route) west to east. The Manchester Ship Canal cuts through the south of the borough (west to east). The M6, M56 and M62 motorways form a partial box around the town and are all accessible through Warrington.
The modern Borough of Warrington was formed in 1974 with the amalgamation of the former County Borough of Warrington, part of the Golborne Urban District, the Lymm Urban District, part of the Runcorn Rural District, the Warrington Rural District and part of the Whiston Rural District.
The earliest known appearance of the name is "Weringtun", when before the Norman Conquest it was the head of a hundred. An entry in the Domesday Book in AD 1086 named it as "Wallintun". The root is likely the Old English word waru – meaning "those that care for, watch, guard, protect, or defend." The suffix -ing is a cognate of inge, an ethnonym for the Ingaevones said variously to mean "of Yngvi," "family, people or followers of" or a genitive plural form of an inhabitant appellation.
