Nine Years' War (Ireland) in the context of "Plantation of Ulster"

The Kingdom of Ireland (Early Modern Irish: Ríoghacht Éireann; Modern Irish: Ríocht na hÉireann, pronounced [ənˠ ˌɾˠiːxt̪ˠ ˈeːɾʲən̪ˠ]) was a dependency of England from 1542 to 1707, and subsequently Great Britain from 1707 to 1800. It was ruled by the monarchs of England and then of Great Britain in personal union, and was administered from Dublin Castle by a viceroy appointed by the English king: the Lord Lieutenant of Ireland. By the late 17th century, the state was dominated by the Protestant Anglo-Irish minority, known as the Protestant Ascendancy. The Protestant Church of Ireland was the state church. The Parliament of Ireland was almost exclusively Anglo-Irish. From 1661, the administration controlled an Irish army. Although formally a kingdom in personal union on equal footing with England and later Great Britain, for most of its history it was de facto a dependency with a viceroy sent as an envoy from London. This status was enshrined in the Declaratory Act 1719, also known as the Irish Parliament Act 1719.

The territory of the kingdom comprised that of the former Lordship of Ireland, founded in 1177 by King Henry II of England and the English Pope Adrian IV, after the Anglo-Norman invasion of Ireland. By the 16th century, the Pale, the area of effective English rule, had shrunk greatly; most of Ireland was held by Gaelic nobles as minor principalities notionally subject to London but independent in practice. By the terms of the Crown of Ireland Act 1542, Henry VIII of England became "King of Ireland", theoretically elevating Ireland to coequal status with England as a kingdom in personal union. There followed an expansion of English control during the Tudor conquest. This sparked the Desmond Rebellions and the Nine Years' War. The conquest of the island was completed early in the 17th century. It involved the confiscation of land from the native Irish Catholics and its colonisation by Protestant settlers from Britain. Most Catholic countries at the time did not recognise Protestant monarchs as legitimate kings of Ireland (or indeed of England), instead supporting the Jacobite government-in-exile from 1688 onwards.

Ireland was conquered by the Tudor monarchs of England in the 16th century. The Anglo-Normans had conquered swathes of Ireland in the late 12th century, bringing it under English rule. In the 14th century, the effective area of English rule shrank markedly, and from then most of Ireland was held by native Gaelic chiefdoms. Following a failed rebellion by the Earl of Kildare in the 1530s, the English Crown set about restoring its authority. Henry VIII of England was made "King of Ireland" by the Crown of Ireland Act 1542. The conquest involved assimilating the Gaelic nobility by way of "surrender and regrant"; the confiscation and colonisation ('plantation') of lands with settlers from Britain; imposing English law and language; banning Catholicism, dissolving the monasteries, and making Anglican Protestantism the state religion.

The Tudor policies in Ireland sparked the Desmond Rebellions (1569–1573, 1579–1583) and the Nine Years' War (1594–1603). Despite Spain sending an armada to support the Irish Catholics during the Anglo-Spanish War (1585–1604), by 1603 the entire country was under English rule. The Flight of the Earls in 1607 largely completed the destruction of the Gaelic aristocracy and left the way open for the Plantation of Ulster, which established a large British Protestant population in the north. Several people who helped establish the plantations of Ireland also played a part later in the early colonisation of North America, particularly a group known as the West Country Men.

On 14 September [O.S. 4 September] 1607, Irish earls Hugh O'Neill, Earl of Tyrone, and Rory O'Donnell, 1st Earl of Tyrconnell, permanently departed Rathmullan in Ireland for mainland Europe, accompanied by their extended families, retinue, followers and fellow nobility, numbering about 100 people. The earls were patriarchs of the two most powerful clans in Ulster—the O'Neill and O'Donnell clans—and their permanent exile is seen to symbolise the end of Gaelic Irish society. This event is known as the Flight of the Earls (Irish: Imeacht na nIarlaí).

Both earls fought against the English Crown in the Nine Years' War (1593–1603), which ended with their surrender. The newly crowned James VI and I granted the earls generous peace terms which allowed them to retain their lands and titles. Many courtiers were unsatisfied with the king's leniency, and hostility towards the earls from British officials gradually increased over time. The implementation of English law in Ireland led to financial difficulties for both earls as well as a major land rights dispute between Tyrone and his vassal Donnell Ballagh O'Cahan, which was weaponised by officials such as Arthur Chichester, John Davies, and George Montgomery.

Tyrconnell (Irish: Tír Chonaill, meaning 'Land of Conall'), also spelled Tirconnell and Tirconaill, was a kingdom of Gaelic Ireland. It is associated geographically with present-day County Donegal, which was officially named County Tirconaill between 1922 and 1927. At times it also included parts of County Fermanagh, County Sligo, County Leitrim, County Tyrone and County Londonderry at its greatest extent. The kingdom represented the core homeland of the Cenél Conaill people of the Northern Uí Néill and although they ruled, there were smaller groups of other Gaels in the area.

From the 5th century founding of Cenél Conaill, the tuatha was a sub-unit of the larger kingdom of Ailech, along with their Cenél nEógain cousins, fellow descendants of Niall of the Nine Hostages. Their initial ascent had coincided with the decline of the Ulaid, whose kingdom of Ulster receded to the north-east coast. In the 12th century the kingdom of Ailech split into two sovereign territories and Cenél Conaill became Tír Chonaill under the Ó Domhnaill (O'Donnell) clan. It was the location of fighting during the Nine Years' War (Ireland) at the end of the 16th century. It continued to exist until the 17th century when it was incorporated into the English-ruled Kingdom of Ireland following the Flight of the Earls.

The Fourth Spanish Armada, also known as the Last Armada, was a military expedition sent to Ireland that took place between August 1601 and March 1602 towards the end of Anglo-Spanish war. The armada – the fourth and smallest of its type, was sent on orders from the Spanish king Philip III to southwestern Ireland to assist the Irish rebels led by Hugh O'Neill, Earl of Tyrone, who were fighting to rid Ireland of Queen Elizabeth I of England's rule. Don Juan del Águila and Don Diego Brochero commanded the expedition that consisted of 36 ships and 4,500 soldiers, and a significant amount of arms and ammunition. The Spanish were also planning to establish a base at Cork from which to strike at England.

Bad weather separated the ships and some had to turn back but the remaining 1,800 men under Águila disembarked at Kinsale on 22 September. Further reinforcements the following month brought the total to 3,500. Admiral Pedro de Zubiaur landed another 700 men in early December at Castlehaven, and sent part of that force commanded by Alonso de Ocampo to Baltimore occupying the castles in the area, Dunboy, Dunasead and Dúnalong (Sherkin Island). The English led by Charles Blount, the Earl of Mountjoy and George Carew, responded in force and were able to besiege Kinsale on 2 October. A small fleet led by Richard Leveson were able to blockade the Spanish at Kinsale by late November. The Irish under Tyrone and clan chief Hugh Roe O'Donnell made their way to Kinsale in a 300-mile march and were joined with 200 Spanish under Alonso de Ocampo.
