County Dublin formed the hinterland of the Irish capital and was comparable to Middlesex in terms of size and economic dependence on its capital city.
The wars of the 1640s and early 1650s had a disastrous impact on County Dublin. The strategic importance of the city of Dublin ensured that the surrounding region experienced periods of intense fighting, and unremitting demands of a large garrison needing food and fodder. Confederate Catholic forces threatened the Irish capital in the winter of 1646-7, and the royalists under the marquess of Ormond besieged the city in the summer of 1649; on each occasion the surrounding area was plundered. Even after the arrival of Oliver Cromwell*, County Dublin remained vulnerable to raids from Irish forces based in the Wicklow Mountains or the midlands, which were difficult to police while the main field army was campaigning in the south of the country.
The elections for County Dublin in the protectorate Parliaments reveal something of the tensions between the different interest groups. On 2 August 1654 the vote was held at St Patrick’s Cathedral, Dublin, and the city’s governor, John Hewson, was returned ‘nemine contradicente’.
Henry Cromwell’s ally, Sir Theophilus Jones, was returned for the third protectorate Parliament of 1659, although the influence of the administration was probably not the deciding factor, as Jones enjoyed considerable prestige as a member of a powerful Old Protestant dynasty, and to this he could add his own status as a landowner in the county, as he had recently acquired the forfeited Lucan estate from the Sarsfield family.
