A Viking influence is evident in Littlethorpe's name. A 'Torp' or 'Thorpe' is an old norse name for a small outlying settlement or homestead, a hamlet or a farmstead.
In the early years of the 11th century, Ripon would have been incredibly filthy but rural areas like Thorpe were probably relatively healthier - especially as it was a scattered community. The Archbishop of York's Manor of Ripon consisted of the township of Ripon plus Bondgate, Bishopton, Bishop Monkton, Sharow, North Stainley, Whitcliffe and Thorpe. In 1086, Torp (Littlethorpe) was recorded in the Domesday book as a vill (a feudal administrative unit containing some combination of farms, hamlets and villages). The population comprised 18 villagers, 21 smallholders, 1 freeman and a thegn - 41 people in all. The land was mostly ploughland but also included 85 acres of meadow, 1 league of woodland, a mill and a fishery. It was an administrative area of Ripon and was called Torp (later Thorpe). The original mediaeval village of Littlethorpe was 200 metres north of present-day Littlethorpe Hall.
Around 1700, the earliest part of Littlethorpe Manor was completed. In 1742, deeds of covenant were drawn up relating to the division of Littlethorpe Moor and, in 1744, the enclosure of common fields of Littlethorpe occurred. By the mid 1700s, the walled garden of Littlethorpe Manor was completed using bricks from Littlethorpe brickworks. In 1788, Roger Pickering built the original Thorpe Lodge and in 1796, there was a major gypsum-related collapse in Littlethorpe.
In the early 19th century, Thorpe Lodge and Littlethorpe Manor were rebuilt. In the census of 1821, the population of Whitcliffe-with-Thorpe was 157. In 1831, a clay works was founded. During the 1860s and 1870s, a great number of fine houses were built as Littlethorpe became a fashionable place for the wealthy of Ripon to live. There was no provision for Anglican worship at this time and those wanting to attend church either had to travel into Ripon or attend a divine service in the school.
The 1901 census revealed that the population of Littlethorpe was 131, living in 30 houses. In around 1907, there was a cricket team in Littlethorpe but Kirkby Malzeard decided not to play them as the Littlethorpe side was deemed 'not strong enough'! Around 1954, Littlethorpe also boasted a football team. In 1964, Miss Pauline Foulds, who had been paralysed from the waist down following a riding accident, won 3 gold medals for swimming at the Paralympic Games in Tokyo. As part of local government reorganisation in 1974, Ripon was given city status and Littlethorpe came under North Yorkshire County Council and Harrogate Borough Council rather than the West Riding.
