Is the Union Written in the Stars? The Astrology of British Disunion
The United Kingdom is a young country pretending to be an ancient one. The name itself dates only to 1801, when the Acts of Union formally joined Great Britain with Ireland into a single state. Scotland had been absorbed into Great Britain nearly a century earlier, in 1707. Before that, England itself, depending on where you choose to start the clock, came into something resembling its modern form with the Norman invasion of 1066. Four nations, three union dates, at least three credible birth charts. The very question of what the UK is astrologically is, in itself, a meditation on the nature of this strange, layered, uneasy country.
That unease is not merely historical. As of 2025, Scotland has had a pro-independence majority in its parliament for the best part of a decade. Wales, which once returned almost entirely Labour members to Westminster, now sends Plaid Cymru MPs who speak openly of eventual self-determination. Northern Ireland, perpetually its own category, has a Sinn Féin First Minister for the first time in its history, and the post-Brexit settlement has already given it a constitutional relationship with the Republic of Ireland that is unlike anything elsewhere in the UK. England itself, bereft of its own national parliament, exists as a kind of constitutional phantom, the largest nation in the union, the one that created it, and the one with the least distinct political identity within it.
The question is not academic. It is the defining constitutional question of British life in the early twenty-first century. And the sky, as it happens, has quite a lot to say about it.
Which Chart? The Problem of Britain's Many Births
Before reading any national chart, a serious mundane astrologer must first answer an awkward question: which one? Nations, unlike people, tend to have multiple plausible birth moments. For the United Kingdom, the main candidates are the coronation of William I on 25th December 1066, which gives England its foundational character; the Act of Union between England and Scotland on 1st May 1707, which created Great Britain; and the Act of Union with Ireland on 1st January 1801, which created the United Kingdom as it was constitutionally named. There is also an argument, advanced by some astrologers, for using April 12th 1927, when the name was formally updated to the United Kingdom of Great Britain and Northern Ireland following Irish independence.
In practice, the 1801 chart is the one most consistently used by working mundane astrologers, and for good reason. It charts the moment the UK as a named political entity came into being. Its planetary positions have been tested repeatedly against major events in British history, the two World Wars, the dissolution of empire, Suez, Brexit, and they hold up to scrutiny. The Sun sits in Capricorn, which captures something essential about the British national character: the emphasis on hierarchy, tradition, endurance, and a deep instinct for institutional self-preservation. The Moon is in Cancer, sign of the home, the family, the private sphere, reflecting the famous English obsession with property and privacy, the castle-as-home. The Libran ascendant describes the outward face Britain presents to the world: moderate, fair-minded, constitutionally polite, and deeply invested in the idea of balance even when the reality is anything but.
The 1707 chart is also worth keeping in mind, particularly when Scotland is the specific subject. That chart, set for the formal union of England and Scotland, has the Sun conjunct the IC, the chart's root and foundation. Astrologers using this chart have consistently noted that Uranus transiting or aspecting key points in it correlates with the periods of greatest Scottish separatist pressure. We will return to both charts. The key point is that in this article, we are reading a nation with layers, and the layers themselves are part of the story.
Pluto in Aquarius: The Great Democratic Unravelling
Whatever chart you use for the UK, the overriding outer-planet context for the 2020s and 2030s is the transit of Pluto through Aquarius, which began in 2023 and will continue until 2044. This is the same transit we examined in our article on the 2026 Senedd election, but its implications for the union as a whole go considerably deeper.
Pluto in Aquarius breaks down collective structures and rebuilds them on different foundations. It is the transit of democratic transformation, of power shifting from old hierarchies to new networks, of the revision of social contracts that have been in place for generations. The last time Pluto was in Aquarius, between 1778 and 1798, the British Empire was at its most aggressive, and yet the seeds of its eventual unravelling were being planted everywhere: in America, in France, in the intellectual ferment of the early Industrial Revolution. The structures Pluto in Capricorn had built and then destroyed between 2008 and 2023, political consensus, institutional trust, the post-war settlement, are now the rubble on which Pluto in Aquarius is constructing something new.
For the UK in particular, the Pluto in Aquarius transit makes a significant aspect to the 1801 chart's natal Jupiter in Scorpio, and will in the coming years make its opposition to the natal Jupiter, a transit that mundane astrologers associate with the overextension and eventual correction of national ambition and institutional power. The UK that emerged from the 1801 union did so on the back of imperial expansion, Capricornian ambition, and a Scorpionic willingness to exercise hard power. Pluto opposing that natal Jupiter, over the course of this decade, is asking a fundamental question: what is left of British institutional identity once its pretensions to global power are stripped away? The devolution question is, in one sense, a version of that same question asked domestically.
Uranus in Gemini: The Nation That Cannot Stop Arguing With Itself
Uranus moved into Gemini in 2025 and will remain there until 2033. In the 1801 chart, Uranus is natally in Libra, and the UK has always had a Libran quality to its internal constitutional disputes, preferring negotiation, gradual reform, and carefully worded compromise over outright rupture. Uranus in Gemini making a trine to that natal Libra Uranus activates it. Trines are often described as easy aspects, but easy does not mean inactive, it means fluid, free-flowing, the energy moving without obstruction. A Uranus-trine-natal-Uranus transit is a Uranus return at the trine phase: an unleashing of the restless, revolutionary energy already present in the chart, expressed through Gemini's domain of communication, information, and the multiplicity of voices.
This transit describes a period when the four nations of the UK simply cannot stop the internal conversation about what they are and what they want. Not just politically, but culturally, linguistically, symbolically. The Welsh language has more institutional support than at any point in its history. Scottish cultural identity is self-consciously distinct from English identity in a way that would have been considered aggressive separatism thirty years ago and is now simply assumed. Northern Ireland's identity has fractured along generational lines, with younger people increasingly comfortable with a dual British-Irish identity that their grandparents would have found untenable. Uranus in Gemini is the transit of the argument that cannot be contained, and for the UK, that argument is about what it actually is.
Saturn Conjunct Neptune in Aries: The Dream and the Structure, Face to Face
The Saturn-Neptune conjunction in Aries that defines 2025 and 2026 has particular resonance for the question of British disunion. Saturn represents the established constitutional order, the Acts of Union, the Westminster system, the monarchy, the settled legal and institutional architecture of the UK state. Neptune represents the dream, the aspiration, the imaginative vision of what a nation could be, which is, at its most transformative, the dream of independence itself.
When Saturn and Neptune conjoin in Aries, as they do now, they are bringing structure and vision into direct collision in a sign that demands action. The independence movements in Scotland and Wales are Neptunian phenomena at heart, motivated by an emotional, imaginative vision of national selfhood that is not primarily economic or strategic in character, even when it dresses itself in economic and strategic arguments. The British state's resistance to those movements is Saturnian, institutional, legalistic, rooted in the weight of what has been built and the fear of what its dissolution would cost.
Aries is not interested in patient negotiation. It is the sign of the charge, the decisive action, the moment when waiting becomes intolerable. A Saturn-Neptune conjunction in Aries does not necessarily produce immediate separation, but it creates the conditions in which the question of independence stops being theoretical and becomes viscerally urgent. The political pressure builds. The institutional resistance hardens. And the meeting of the two, in an impatient fire sign, makes the eventual outcome something that will be resolved one way or another, not postponed indefinitely.
The 1707 Chart and Scotland: A Divorce in Slow Motion
The Act of Union of 1707, the specific chart of the marriage between England and Scotland, has been producing significant transits for two decades. Uranus transiting key degrees of this chart has repeatedly corresponded with the high-water marks of Scottish independence politics: the SNP's landslide in 2011, the 2014 referendum, the extraordinary 2015 general election result when the SNP won 56 of 59 Scottish Westminster seats. Pluto in Capricorn made a prolonged transit over the 1707 Sun during the Brexit years, a transit often associated with the forced reckoning with power and control in a relationship.
The 1707 chart has the Sun conjunct the IC, the very root of the chart, its deepest, most foundational point. In a national chart, the IC represents the homeland, the ancestral ground, the emotional bedrock. That Pluto spent years grinding over this point during Brexit is not incidental. Brexit was, among many other things, a fracture between English and Scottish political identities so profound that it made the 55-45 result of the 2014 referendum look like ancient history. In 2014, Scots voted to remain in the UK partly because they were told independence would mean leaving the EU. In 2016, they were taken out of the EU anyway, against the clear majority will of the Scottish electorate. The constitutional injury of that sequence has not healed.
What the 1707 chart shows over the coming decade is continued activation of those foundational degrees. Uranus in Gemini makes aspects to the chart's nodal axis, and the longer arc of Pluto in Aquarius will eventually oppose key points in the chart's cardinal architecture. These are not transits that suggest stability and quiet persistence. They are transits that suggest a structure under sustained pressure, being asked at a fundamental level whether it still wants to be what it has been.
Wales: The Slowest River
Wales presents a different astrological picture, and in some ways a more psychologically interesting one. Unlike Scotland, which has a credible foundational chart and a clear political movement with a long institutional history, Wales is harder to read through any single chart. The devolution settlement of 1997-1999 created a Welsh Assembly (now Senedd) with considerably fewer initial powers than the Scottish Parliament, and Welsh independence has historically polled at much lower levels than its Scottish equivalent.
But something is shifting. The Senedd election of 2026, which we examined in our previous article, takes place at a moment of genuine realignment in Welsh politics. Jupiter in Cancer, the sign of homeland and roots, has been supporting a renewed Welsh national consciousness that is not simply political but cultural and linguistic. The Welsh Language Act, the expansion of Welsh-medium education, the growing visibility of Welsh cultural identity in ways that have no equivalent in England, these are Cancerian phenomena, rooted in a sense that something worth protecting is at stake.
In the longer arc of Pluto in Aquarius, Wales faces a question that is less immediate than Scotland's but perhaps more existential: what is Wales, exactly, in a post-union political landscape? If Scotland becomes independent, and Northern Ireland edges toward reunification, what does the remaining structure look like? An England-and-Wales rump? An increasingly autonomous Welsh nation within that structure? A Wales that, having watched its neighbours go, discovers its own appetite for something more? The transit of Pluto through Aquarius over the coming two decades will make aspects to the Senedd's own natal chart that suggest sustained transformation of Welsh democratic identity. The river is slow, but it is moving.
Northern Ireland: The Chart That Cannot Be Written
Northern Ireland is the constitutional anomaly that astrology finds most difficult to address, not because the astrology is unclear, but because the political reality is so layered that no single chart can capture it. Northern Ireland was created in 1922 as a provisional solution to an insoluble problem, and it has remained provisional ever since. Its constitutional status has been, at various times, a matter of war, ceasefire, power-sharing, collapse of power-sharing, and the post-Brexit protocol that gave it a unique dual-market status that is genuinely unlike anything in British constitutional history.
What the broader planetary weather says about Northern Ireland is this: Pluto in Aquarius is the transit of the dissolution of old binary categories. For a century, the fundamental constitutional question of Northern Ireland has been framed in binary terms, British or Irish, Unionist or Nationalist, Protestant or Catholic. Pluto in Aquarius does not resolve binaries. It makes them feel suddenly inadequate, outdated, too small to contain the complexity of lived experience. The generational shift in Northern Irish identity, with younger people self-describing as Northern Irish rather than British or Irish, or as both, is a Plutonian-Aquarian phenomenon. It is not that the old categories no longer matter. It is that they no longer exhaust the possibilities.
In the coming decade, the pressure for some form of Irish unity referendum will intensify. The astrology of Ireland's own founding chart and the UK's 1801 chart suggest that the period between 2028 and 2033, when both Uranus in Gemini and Pluto in Aquarius are making simultaneous significant aspects to key points in both national charts, is the window of maximum constitutional instability across the island of Ireland and the British Isles as a whole.
The UK's Pluto Return: What Empires Do When They Run Out of Empire
One of the most significant mundane astrological events of recent decades is the Pluto return, the moment when Pluto, in its approximately 248-year orbit, returns to the degree it occupied in a nation's founding chart. The United States had its Pluto return in 2022, and the political convulsions of that period need no introduction.
The UK's 1801 chart has natal Pluto at 3° Pisces. Pluto will not reach Pisces again until 2043, meaning the UK's Pluto return is still two decades away, but it is already in the approach. Pluto in Aquarius is moving through the twelfth house of the 1801 chart (depending on house system), the house of hidden matters, institutional undercurrents, what is being dissolved before it fully manifests. A Pluto twelfth-house transit is one of the most psychologically charged passages in a national chart, it is the phase in which the deepest compulsions and shadow material of a collective identity are forced to the surface, usually through events that feel threatening, disorienting, and uncontrollable. The constitutional crisis of British identity, the Brexit rupture, the devolution pressure, the questioning of the monarchy, the loss of global standing, is the Plutonian shadow material of the 1801 chart coming through its twelfth house.
What gets destroyed in a Pluto twelfth-house transit is whatever was being maintained by avoidance. For the UK, that means the pretence that its internal contradictions can be managed indefinitely by the old toolkit of constitutional fudge and institutional inertia. Pluto does not permit indefinite deferral. It will have its reckoning.
Does the Union Break? What the Astrology Actually Says
Astrology, as we always say at this clinic, does not determine outcomes. It describes the quality of time, the pressures, the archetypal forces, the energies that are active at a given moment. With that caveat firmly in place, what the planetary picture of the 2020s and 2030s says about the UK is this: the union is under more structural astrological stress than at any time since the Irish partition of 1922. The transits are not minor. They are generational. And they are occurring simultaneously, which means they reinforce rather than cancel each other out.
Pluto in Aquarius dissolves old collective structures and demands new ones. Uranus in Gemini makes the internal conversation about identity uncontainable. The Saturn-Neptune conjunction in Aries brings the dream of national selfhood and the structure of the existing state into direct, urgent collision. Jupiter in Cancer amplifies the emotional power of homeland and roots. These are not the transits of a union quietly renewing itself. They are the transits of a union being asked, with considerable planetary insistence, to account for itself.
History suggests that the UK is extraordinarily resilient. The Capricorn Sun of the 1801 chart is not easily broken, Capricorn preserves, endures, adapts its form while maintaining its essential structure. The Libran ascendant finds compromise where others find impasse. It is entirely possible that the union survives the coming decades in some modified form, more genuinely federal, more genuinely respectful of the distinct national identities within it, less centred on a Westminster model that was designed for a different era.
But it is also possible, and the astrology suggests it is more than merely possible, that one or more of the four nations finds its way out. The window of maximum pressure, based on the transits to both the 1707 and 1801 charts, appears to run from approximately 2028 to 2035. Before then, the question is being asked. During that period, it may be answered.
A Jungian Note: The Shadow of Empire
At the Wilfred Hazelwood Clinic, we rarely read astrological events in purely political terms. The planets describe both outer events and inner realities, collective psychological processes as much as constitutional ones. The question of British disunion is not only a political question. It is a psychological one: what happens to a collective identity that was built on the project of empire, when that project has definitively ended?
Jung wrote extensively about the shadow, the parts of ourselves we have disowned, suppressed, or failed to integrate. For the British collective, the shadow of empire is enormous and largely unprocessed. The wealth extracted from colonised peoples, the violence that maintained it, the complex self-image of benevolent civiliser that was used to justify it, none of this has been genuinely metabolised at the level of national consciousness. It sits in the shadow, generating distorted versions of itself: the fantasy of global importance, the reflexive mistrust of European entanglement, the nostalgia for a past whose actual texture is not remembered clearly.
Pluto in Aquarius is, among many other things, the transit of shadow work at the collective level. What cannot be acknowledged cannot be integrated. What cannot be integrated cannot be transformed. The constitutional crisis of the UK is, through this lens, a symptom of a deeper psychological process, the painful, necessary, and ultimately potentially redemptive work of a collective identity trying to discover who it actually is, once it has stopped being what it once was.
Whether that process ends in a reformed, more honest union or in a peaceful separation into its constituent parts, the astrology suggests it will not end soon, and it will not end without significant change. The stars have written nothing, finally, the outcome remains genuinely open. But they have written the question clearly enough. The United Kingdom is being asked, by forces considerably larger than any single government or political party, what it truly is. How it answers may be the defining story of the next generation of British life.
