The High Sheriff of Berkshire, in common with other counties, was originally the King's representative on taxation upholding the law in Saxon times. The word Sheriff evolved from 'shire-reeve'.
Unlike the Lord Lieutenant of Berkshire, which is generally held from appointment until the holder's death or incapacity, the title of High Sheriff is appointed / reappointed annually. The High Sheriff is assisted by an Under-Sheriff of Berkshire.
