"Crendon" was the caput of the feudal honour held by Walter Giffard (died 1102), created Earl of Buckingham by William the Conqueror.
The Manor in Long Crendon was once a great building that housed the later Earls of Buckingham and over the years the various manorial estates in the village have passed through the hands of the Crown, Oxford University, the Earls of March and the Marquis of Buckingham.
The latter is now the Lord of the Manor of Long Crendon.

In 1162 an order of Augustinian monks was founded in the village at nearby Notley Abbey.
The park in which the abbey stood was donated to the abbey itself by the incumbent of the manor, the Earl of Buckingham.
At the time of the Dissolution of the Monasteries the annual income was calculated as over £437; an immense amount of money for the time.
The abbey still stands, but as a secular manor house.
In the 20th century it was the marital home of actors Sir Laurence Olivier and Vivien Leigh.

In 1218 Long Crendon was granted a royal charter to hold a weekly market; the monies from which were to be collected by William Earl Marshall who owned the manor at that time.
 The town (as it was then) was certainly important in this period as it shared the distinction with Aylesbury as being the only places in the whole of England where needles were made.
The royal charter was later rescinded and the market moved and joined with the existing one in nearby Thame.

The Church of England parish church of St Mary dates from the 12th century.
The building has undergone several major renovations and refurbishments since 2007.
The village has also a Baptist church and a Roman Catholic church.

Long Crendon Courthouse is a 15th-century timber frame building.
Manorial courts were held here from the reign of King Henry V until the Victorian era.
The National Trust bought the courthouse in 1900.
The lower floor is residential; the upper floor can be visited.

There was a Long Crendon Rural District from 1894 to 1934.
