The High Sheriff of Hertfordshire was an ancient Sheriff title originating in the time of the Angles, not long after the invasion of the Kingdom of England, which was in existence for around a thousand years. On 1 April 1974, under the provisions of the Local Government Act 1972, the title of Sheriff of Hertfordshire was retitled High Sheriff of Hertfordshire. The High Shrievalties are the oldest secular titles under the Crown in England and Wales, their purpose being to represent the monarch at a local level, historically in the shires.
