The Plantation of Ulster: Dividing the Land

Sure, It's Only History

In the last episode, we watched the last of the great Gaelic earls sail away from Lough Swilly on a September morning in 1607. Hugh O'Neill. Rory O'Donnell. Ninety souls on a small ship, heading into exile and never coming back.

We said that the old Ireland went with them.

Today we find out what replaced it.

Because the Flight of the Earls was not just a personal tragedy. It was an opportunity. And the English Crown — specifically King James I and his Lord Deputy in Ireland, Sir Arthur Chichester — moved quickly and ruthlessly to take it.

Billy Galligan

Within weeks of the earls' departure, their lands were declared forfeit. Not just their personal estates. Six entire counties of Ulster — Armagh, Coleraine, Cavan, Donegal, Fermanagh and Tyrone. The heartland of Gaelic Ireland. Gone. Declared the property of the Crown by virtue of the earls' flight, which was interpreted as treason.

And then came the plan.

Billy Galligan

The Plantation of Ulster took roughly two years to design. It went through several drafts. Chichester initially had different ideas — some land for loyal Irish, some for settlers. But by 1610, the final shape had emerged, and it was more radical than anything that had been attempted before.

Billy Galligan

The plan divided the confiscated land among three types of settlers.

Billy Galligan

First, the Undertakers. These were English and Scottish Protestant landlords who received the largest grants of land — typically between one thousand and two thousand acres each. In return, they were required to bring in a set number of British Protestant tenants and to build fortified settlements within a fixed number of years. Crucially, they were forbidden from having native Irish tenants on their land. This was not just colonisation. It was designed to be a wholesale demographic replacement.

Second, the Servitors. These were English soldiers and officials who had served the Crown in Ireland and were rewarded with land grants. They were permitted, unlike the Undertakers, to have some Irish tenants — but were required to keep strict control over them.

Billy Galligan

Third, and this is the detail that often gets overlooked — some Gaelic Irish lords were allocated land. But not the good land. The Gaelic Irish who received grants were given the poorer, more isolated territory. The hill land. The bog land. The ground above five hundred feet, where farming was harder and life was more precarious. Below that line, in the fertile valleys and along the rivers — that was for the planters.

Billy Galligan

Five hundred feet above sea level. That was the line between the old world and the new one.

Now let's talk about where these settlers came from. Because it was not just England. It was Scotland. Specifically, the Scottish Lowlands — Protestant Presbyterians crossing the narrow stretch of water between Ayrshire and Antrim to take up the land grants on offer. In some parts of Ulster, particularly in counties Antrim and Down — which were not even part of the official plantation but saw private settlement — the Scottish presence became overwhelming. By the 1720s, British Protestants were the majority population in Ulster.

The city of Londonderry — Derry — carries the story of the Plantation in its very name. In January 1610, articles of agreement were signed between the City of London and King James I for the colonisation of the county that would become known as Londonderry. The great London trade guilds — the Drapers, the Fishmongers, the Grocers, the Mercers — were given land in exchange for financing the construction of the new city. A merchant city, built on confiscated Gaelic land, funded by London money, named for London itself.

Billy Galligan

The native Irish of Derry — the O'Cahans whose land it had been — found themselves pushed to the margins of what had recently been their own territory.

Billy Galligan

And what happened to those native Irish? This is the part that gets uncomfortable. The original plan had called for the removal of all native Irish from the plantation lands. In practice, full removal proved impossible — there were too many people, and the settlers needed labour. So what happened instead was a slow, grinding displacement. The best land was taken. The Irish were pushed to the edges. Legal protections that had existed under Brehon law — the ancient Irish legal system — were abolished and replaced with English common law, in which the new settlers had all the advantages.

Billy Galligan

The Irish language, which had been the language of law, poetry, history and daily life across the province, was sidelined. English became the language of power, of commerce, of the courts. The Irish language began to decline after the earls departed in 1607 and English became the language of those who held authority.

Billy Galligan

The plantation also brought a new religious fault line to Ulster that had not existed before — not in the same way. The native Irish were Catholic. The settlers were Protestant — Church of England or Presbyterian. And because land, power, religion and identity were now bundled together on opposite sides of the same divide, the tension that resulted was not just economic or political. It was existential. Each community defined itself partly in opposition to the other.

Billy Galligan

That fault line has never fully closed. The Plantation of Ulster in 1610 is the root of the religious and political divisions that defined Northern Ireland's conflict in the twentieth century. The Troubles — the decades of violence that killed over three thousand people — cannot be understood without understanding what was planted in Ulster four hundred years earlier.

Billy Galligan

And it is worth being honest about what the Plantation was. It was a colonial enterprise. Land was taken from people who had lived on it for generations and given to strangers brought in from across the water, specifically because of their religion and their loyalty to the Crown. The justifications given at the time — that the Irish were uncivilised, that they needed to be improved, that the land was being put to better use — are the justifications of every colonial project in history. They do not hold up well under scrutiny.

Billy Galligan

Now. There were those who resisted. Banditry — what the English called wood-kernes — was widespread in the early years of the Plantation. Irish men who had lost their land took to the forests and the hills and made life difficult for the settlers where they could. It was not organised resistance on the scale of the Nine Years War. But it was resistance nonetheless.

Billy Galligan

And the tensions simmered and built for decades, until they finally erupted in 1641 in a rebellion that shook Ulster to its foundations — killing thousands of settlers and triggering a spiral of violence that would eventually bring Oliver Cromwell to Ireland's shores. But that is a story for another episode.

Billy Galligan

The Plantation of Ulster is the bridge between the Flight of the Earls and everything that came after. It is the moment when a military and political defeat became a demographic transformation. When the loss of the earls became the loss of the land. When the old Gaelic world did not just fade — it was actively, deliberately replaced.

Billy Galligan

Hugh O'Neill died in Rome in 1616, never knowing the full scale of what had been built on the ruins of his world. The land of his people — the land of the O'Neills and the O'Donnells and the O'Cahans — was divided up on parchment in London offices and handed to strangers with Protestant names and Scottish accents.

Billy Galligan

The Flight of the Earls was the end of the old Ireland. The Plantation of Ulster was the beginning of something new. Something that is still, four hundred years later, unresolved.

Billy Galligan

Sure, it's only history. But in Ulster, it never quite stopped being the present.
