thumb|right|200px|badge of the cheshire coat of arms  the history of cheshire can be traced back to the hoxnian interglacial, between 400,000 and 380,000 years bp. primitive tools that date to that period have been found. stone age remains have been found showing more permanent habitation during the neolithic period, and by the iron age the area is known to have been occupied by the celtic cornovii tribe and possibly the deceangli. the romans occupied cheshire for almost 400 years, from 70 ad, and created the town and fort of deva victrix, now chester. after the romans withdrew, cheshire formed part of mercia, an anglo-saxon kingdom, that saw invasions from the welsh and danes. the norman conquest in 1070 saw cheshire harshly ruled by the occupiers as local people resented the invaders and rebelled. war again swept the county during the english civil war in 1642, despite an attempt by local gentry to keep the county neutral. the industrial revolution saw population changes in cheshire as farm workers moved to the factories of manchester and lancashire. in the 18th and 19th centuries there was a resurgence in the country houses of cheshire and canals and railways were built. contemporary cheshire is now a ceremonial county administered by four unitary authorities; cheshire east, cheshire west and chester, halton, and warrington. (warrington, formerly in lancashire, was added to cheshire in 1974.) cheshire retains the offices of lord lieutenant and high sheriff for ceremonial purposes. ==toponymy== cheshire's name was originally derived from an early name for chester, and was first recorded as legeceasterscir in the anglo-saxon chronicle,harris, b. e. and thacker, a. t. (1987). p. 237. meaning the shire of the city of legions.crosby, a. (1996). page 31. although the name first appears in 980, it is thought that the county was created by edward the elder around 920. in the domesday book, chester was recorded as having the name cestrescir (chestershire), derived from the name for chester at the time. a series of changes that occurred as english itself changed, together with some simplifications and elision, resulted in the name cheshire, as it occurs today. ==prehistory== cheshire periodically lay under ice until the end of the younger dryas ice age about 11,500 years ago. however, primitive tools have been found that date to the [[hoxnian stage|hoxnian i
