Macosquin’s Unmade Rising1615 CE

Dateline

A Province Under Watch

In 1615, Ireland was governed in the name of King James I by Sir Arthur Chichester, lord deputy since 1605. The great wars of the previous reign had ended, but peace had not made the kingdom settled. Nowhere was this clearer than Ulster. The flight of the earls in 1607, the defeat of Sir Cahir O’Doherty in 1608, and the ensuing confiscations had opened immense territories to the crown. The Plantation of Ulster was changing ownership, settlement and authority across six escheated counties. English and Scottish undertakers received estates on conditions: they were to build, bring in British Protestant tenants and form defensible villages. Native Irish communities, meanwhile, faced removal from some lands, insecure tenures on others, and the daily presence of new landlords, courts, garrisons and boroughs.

That setting is essential to the best-attested political crisis of the year. On 18 April Chichester informed the English privy council that a conspiracy had been discovered in Ulster. Government reports described plans to seize principal towns and kill Protestant settlers. The episode was soon labelled the “Native’s Rebellion”, though that imposing name can mislead. There was no general rising, no captured town and no campaign in the field. What survives points instead to a small, badly equipped and abortive conspiracy, pursued with exceptional official alarm. The gap between the government’s fearful language and the plotters’ practical capacity is itself a revealing fact about Ireland in 1615.

The Macosquin Plot

Accounts associate the scheme with a meeting at Macosquin, near the River Bann in north-west Ulster. Men linked to old Gaelic networks allegedly discussed attacking settlements including Derry and Coleraine. Among those accused were Hugh McShane O’Neill, Brian Crossagh O’Neill, Rory O’Cahan and Alexander MacDonnell. Their names invoked families whose standing had been gravely weakened by conquest and plantation. Yet family name did not equal military power. The supposed plotters had few arms, little prospect of broad co-ordination and no demonstrated foreign force ready to land in support.

Nevertheless, fears of intervention gave the affair a larger diplomatic shadow. Hugh O’Neill, the exiled earl of Tyrone, remained in continental Europe and still sought Spanish assistance for an Irish return. Spain, however, had strong reasons to avoid provoking James’s government while wider negotiations were in play. It is therefore unsafe to present the 1615 conspiracy as an O’Neill-directed invasion plan. It is safer to say that officials interpreted local disaffection through the memory of the Nine Years’ War, the recent flight of the Ulster earls and the continuing possibility—however remote—of help from Catholic powers abroad.

The investigation showed the coercive edge of the new order. Cú Chonnacht Ó Cianáin, a poet, chronicler and member of a learned family long connected with the Maguires of Fermanagh, was arrested. He was also a yeoman associated with Moygh in County Antrim. Later accounts identify him as the first person known to have been subjected to judicial torture on the rack in Ireland. The evidence must be handled carefully: torture was intended to extract information, not to establish reliable truth, and surviving official accounts came from the side determined to prove danger. Yet the fact that the rack was used is significant. A government confident enough to remake Ulster’s landholding was still sufficiently anxious to employ extreme methods against suspected resistance.

In July, seventeen defendants were tried at Derry before assize judges and a jury that included native Irishmen. Eleven were acquitted for want of evidence. Six, including Ó Cianáin and Brian Crossagh O’Neill, were convicted on 31 July and sentenced to the full traitor’s death. Brian Crossagh was executed promptly; Ó Cianáin appears to have been hanged later in 1615. The acquittals complicate any simple story of a sweeping rebellion. They suggest that even within a strongly managed colonial and judicial environment, proof did not sustain every accusation. The convictions and executions, however, made a clear public warning: dissent around plantation lands would be treated as treason.

Plantation’s Uneven Ground

The conspiracy occurred during a year in which the Ulster Plantation was itself assessed. Surveys undertaken in 1611, 1615, 1619 and 1622 repeatedly found that stated targets were not being met. Many undertakers had not completed the castles, bawns and towns demanded by their grants; some planned settlements existed more confidently on paper than on the ground. Nor had landlords consistently removed native Irish inhabitants, in part because Irish tenants paid rents and supplied labour that new estates urgently needed. Plantation was therefore not a finished replacement of one people by another. It was an uneven, contested remaking of countryside, markets, tenures and local power.

For ordinary people, this meant adaptation as well as dispossession. A household might find itself working for a new landlord, moving to poorer ground, maintaining a holding under new written conditions, or living beside settlers who brought different farming practices, churches and legal expectations. Newcomers also faced hazards: uncertain returns, incomplete buildings, hostile rumours and the expense of securing estates. The government’s reaction to the 1615 plot shows how precarious the project still appeared to its architects. Yet its incompleteness should not be mistaken for insignificance. By altering titles to land and encouraging migration, plantation was already producing a durable regional transformation.

Parliament’s Closing Session

The political year was also marked by the final session of the Irish parliament elected in 1613. It assembled on 18 April and sat until 16 May; on 24 October James dissolved it. This was the parliament in which the crown had engineered a Protestant majority partly through the creation of new boroughs, many in plantation districts. Its opening had been acrimonious, with Old English Catholic members challenging the legitimacy of the electoral arrangements and the choice of Speaker Sir John Davies. By 1615, disputes over religion, representation, land and royal finance still shaped relations between Dublin Castle and the kingdom’s Catholic political elites.

The reported Ulster danger strengthened Chichester’s position at a useful moment. It made security, rather than concessions to recusants, the urgent language of government. Parliament nevertheless passed measures with consequences far beyond elite manoeuvring. A highways act made parishes responsible for road maintenance. It required local organisation and a statutory contribution of labour: landholders were to provide men, horses, carts and tools for a number of days’ work. The burden fell into the calendar of rural life, when labour and animals were valuable. Better roads were desirable for travel, markets, royal administration and military movement; the cost was imposed locally and unevenly.

Other April proclamations illuminate smaller, practical concerns. One regulated the holding of fairs and markets on Sundays, projecting Protestant ideals of Sabbath observance into commercial routine. Another made specified Spanish silver current in Ireland. Neither order tells us precisely what every household used or believed, but together they show a government concerned with the rhythms of worship and trade, and with the circulation of coin across an Atlantic-facing and European-connected kingdom.

A Confession for the Established Church

On 25 April, while parliament was sitting in Dublin, the Church of Ireland’s convocation concluded by approving 104 Articles of Religion. This is one of the year’s firm landmarks. The articles were an extensive doctrinal statement for the established church, and James Ussher—then a Trinity College Dublin scholar-cleric and professor of theological controversies—was probably their principal drafter or editor. The surviving record does not allow absolute certainty over authorship, so it is better not to call the work simply “Ussher’s articles”. His influence, however, was unmistakable.

The Irish Articles proclaimed a strongly Reformed, Calvinist position. They treated scripture as the rule of faith, incorporated the predestinarian emphases of the Lambeth Articles, and named the pope as Antichrist. They went beyond the Church of England’s Thirty-nine Articles in detail and sharpness. Their adoption gave the Church of Ireland a distinctive confessional formulation at precisely the moment when the state was trying to secure Protestant settlement and political predominance. But doctrine approved in Dublin should not be confused with uniform religious conversion in the country. Most of the population remained Catholic, and Catholic clergy, worship and networks persisted despite official pressure.

Religion in 1615 was therefore a field of institutions as well as belief. A royal visitation, ordered in June, examined the condition of the Church of Ireland across much of Leinster, Munster and Connacht, with more limited coverage in the ecclesiastical province of Armagh. Its enquiries concerned clergy, their education, the value of livings and the state of church buildings. The very need for such a nationwide inspection indicates the practical fragility behind the new confession: parishes varied enormously in resources, resident ministry and usable fabric. In parts of the plantation zone, Protestant clergy and congregations were growing; elsewhere the established church’s legal claims far exceeded its popular reach.

An Unsettled Settlement

Thus 1615 was not a year of a successful Irish rebellion, nor a year in which plantation or Protestant reform achieved their declared ends. It was a year in which the state answered a limited Ulster conspiracy with torture, trials and executions; closed a parliament designed to reinforce royal authority; issued a formidable Protestant confession; and turned parish labour towards roads. These developments joined high policy to ordinary experience. They affected where people lived, how they travelled, which church held legal authority, how markets were timed and what risks attached to old political loyalties. The unmade rising at Macosquin did not overturn the new Ulster. Its suppression instead exposed how much force, surveillance and uncertainty lay beneath the appearance of post-war peace.
