Flaxby was once part of the wapentake of Claro.[3]
It is also part of the ecclesiastical parish of Goldsborough (St Mary).[4]
In 1994, an Early Iron Age farmstead of the 7th–6th centuries BC was discovered by archaeologists, but the site was abandoned until the late Roman period.[5]
Proposals have been put forward to develop the land to the east of Flaxby, north of the A59 road and west of the A1(M) motorway into a new town called Flaxby Park. The developers have announced their intention to build 2,500 - 3,000 homes on 440 acres (180 ha) of land that would also see a primary school, a medical centre, leisure facilities and numerous shops and bars.[6] The development would also include a bus park and ride system with the possibility of a new railway station on the York to Harrogate line. A railway station has already been proposed at Flaxby Moor (south of the A59) but in 2014, a feasibility study of new stations predicted a low demand of passenger numbers from a new station on the line.[7][8]
In 2017, Harrogate Borough Council opted to put forward a housing scheme at nearby Cattal called Maltkiln, instead of the development at Flaxby.[9]
