Before the English Civil War, the lieutenancy of Monmouthshire was held by the Lord Lieutenant of Wales, except for the period from 1602 to 1629, when it formed a separate lieutenancy in conjunction with Glamorgan. After the English Restoration in 1660, it was again held by the Lord Lieutenant of Wales from 1672 until 1694, when the twelve central Welsh lieutenancies were divided. After 1715 each office holder was also Custos Rotulorum of Monmouthshire. The combined position was finally abolished on 31 March 1974 and replaced with that of the Lord Lieutenant of Gwent.
