How a centuries-old astrological cycle illuminates political upheaval, technological change and the redistribution of global power.

Who holds power when the systems we depend on begin to change? For a business owner, this is no abstract question. A border closes, a platform changes its rules or a new technology overturns an established market, and yesterday’s advantage can become tomorrow’s vulnerability.

For more than a millennium, astrologers have studied the conjunction of Jupiter and Saturn — their meeting in the zodiac — to interpret changes in collective power. This article follows that cycle through history and asks what its latest transition might illuminate about the world in which we live and work.

How the cycle works

In astrology, Jupiter represents expansion. It traditionally rules Sagittarius, associated with travel, law and aspiration, and Pisces, associated with belief, imagination and surrender. Mundane astrology — the study of collective events rather than individual lives — connects Jupiter with faith, trade, opportunity and public ambition.

Jupiter’s promise is abundance; its shadow is excess. Confidence can become speculation, financial bubbles or imperial overreach. Growth can continue long after its foundations have weakened. Jupiter symbolises expansion, but expansion alone does not tell us when enough is enough.

Saturn supplies the counterweight. It limits and consolidates, governing the laws, institutions, borders and systems that determine what can endure and what has reached its limit. Together, Jupiter and Saturn describe the tension between growth and consequence, ambition and structure, possibility and time.

Jupiter and Saturn meet approximately every twenty years. Successive conjunctions occur roughly 120 degrees apart, forming a broad triangular pattern through the zodiac. They tend to repeat in signs of the same element — Fire, Earth, Air or Water — for around two centuries, with interruptions during the transitions. Astrologers call the shift from one element to another a great mutation: a twenty-year cycle within a much longer historical framework.

By the ninth century, the Persian astrologer Abu Maʿshar had made Jupiter–Saturn conjunctions central to historical astrology. In The Book of Religions and Dynasties, he used them to interpret changes in rulers, religions, wars and the wider political order.

The appeal to rulers was obvious: a method that claimed to identify the rise and fall of dynasties spoke directly to the security of their own power.

These transitions are gradual. The 1802 conjunction in Virgo introduced Earth, but the 1821 meeting returned briefly to Fire. Similarly, the three Libra conjunctions of 1980–81 previewed Air, before the planets met in the Earth sign Taurus in 2000. The 2020 conjunction began the sustained return to Air.

The historical examples below are an astrological reading of selected events, rather than evidence that planets caused them. Their value lies in the questions they raise about how power changes hands and how institutions respond.

Air: networks and contagion

The previous Air sequence, spanning much of the thirteenth and fourteenth centuries, offers a striking comparison. The Mongol Empire connected large parts of Eurasia through trade and diplomatic routes along which goods, technologies and information circulated. In England, the Model Parliament of 1295 brought county and town representatives together, while universities and merchant communities gained influence.

Those connections also carried danger. The Black Death spread through trade networks, devastating Europe from 1347. Estimates of mortality vary, but a historical account published by Harvard’s Weatherhead Center puts the loss at roughly one in three Europeans by 1352. Repeated outbreaks deepened the demographic and economic upheaval.

Read symbolically, Air describes circulation: networks can spread knowledge and opportunity, but also disease, fear and propaganda.

Water: the struggle for belief

The Water sequence provides a different set of historical parallels, centred on faith and maritime expansion. Constantinople fell to the Ottomans in 1453; Columbus crossed the Atlantic in 1492; Luther challenged papal authority in 1517. Maritime empires expanded as the Reformation fractured Christian Europe. Religious authority and control of sea routes became powerful instruments of political competition.

Fire: the age of revolution

The Fire sequence coincided with repeated struggles over sovereignty. The Thirty Years’ War began in 1618 and ended with the Peace of Westphalia in 1648. England’s Bill of Rights of 1689 limited royal power. Then came the American Declaration of Independence in 1776, the French Revolution in 1789 and the Haitian Revolution of 1791–1804.

These events challenged inherited authority and the divine right of rulers. Haiti became the second independent republic in the Americas and the first to emerge from a successful revolt by enslaved people. Fire’s symbolism finds a forceful expression in this struggle over who has the right to govern.

Earth: the machinery of scale

The Earth sequence, first signalled in 1802, overlapped with the expansion of the industrial world: factories, railways, extraction, banks and corporations. Industrialisation was already under way, but its scale and political consequences grew dramatically during the nineteenth and twentieth centuries.

These centuries brought nationalism, two world wars, decolonisation and the institutions that still shape global finance and diplomacy. Power could be measured in territory, industrial output, labour and balance sheets.

World population grew from approximately one billion in 1800 to eight billion in 2022. As people moved into cities for work, factories, banks and corporations accumulated greater wealth and influence. These developments reflect Earth’s astrological themes: land, ownership, material resources and the consolidation of power.

The Air era and the new political contest

The Libra conjunctions of 1980–81 offered an early preview of Air. Under Margaret Thatcher and Ronald Reagan, economic liberalisation reshaped trade and finance, while personal computers and the emerging internet transformed communication. The Berlin Wall fell in 1989 and the Soviet Union dissolved in 1991. Political power and the means of exchanging information were being reorganised.

The 2000 conjunction in Taurus returned the cycle to Earth. It also offers a useful reminder: the digital economy still depends on cables, minerals, energy and land.

On 21 December 2020, Jupiter and Saturn appeared about 0.1 degrees apart: their closest conjunction since 1623 and the closest readily visible since 1226. Astrologically, they met at 0° Aquarius, marking the sustained shift from predominantly Earth conjunctions to Air.

In contemporary interpretation, this shift directs attention towards intellectual property, technological innovation and interconnected societies. Aquarius brings questions of collective organisation, equality and the rules by which communities operate. It invites us to examine outdated structures, without assuming that every replacement will be fairer.

Such transitions are rarely orderly.

The central tension is freedom and control. Networks can challenge established hierarchies, yet concentrate extraordinary power in the hands of those who own them. Innovation can coexist with ideological extremism, social fragmentation and information overload. The same technology that expands our choices can also monitor and restrict them.

By the time Jupiter reached Saturn in December 2020, COVID-19 had already brought much of the world to a standstill. First reported in late 2019, the outbreak became a pandemic in March 2020. Borders closed, businesses moved online and restrictions reshaped daily life. The pandemic accelerated digital dependence and widened debates about monitoring, privacy and state authority.

Aquarius is traditionally ruled by Saturn; modern astrology also associates it with Uranus, a symbol of disruption, rebellion and invention. Air offers a metaphor for rapid circulation through society, including ideas, commerce and contagion.

What this means for the commercial world

For lawyers, this raises questions about jurisdiction, data ownership and regulations that reach across borders. For financiers, it highlights the importance of intellectual property and digital networks, alongside the physical infrastructure that supports them.

For founders, the practical question is dependence: how much of the business rests on platforms, suppliers or information systems beyond their control? Resilient partnerships and reliable systems matter as much as speed.

For geopolitical advisers, semiconductors, satellites and control over information belong in the same conversation as territory, critical resources and military force.

Questions for the boardroom

The cycle becomes useful when it prompts sharper questions. Business leaders can begin with these:

  • Is the value of our business still tied mainly to physical assets and territory, or increasingly to data, networks and access?
  • How exposed are we if a major platform changes its rules, restricts our access or removes us altogether?
  • How well could we continue to operate if governments tightened control over data, digital infrastructure or cross-border access?
  • Are we taking cyber risk and reputational damage as seriously as the liabilities on our balance sheet?

Astrology does not replace due diligence. I use the Jupiter–Saturn cycle as a historical lens for questioning assumptions about growth, authority and change. Its most useful question is practical: which structures still support us, and which have become a liability? That is the kind of question explored in Business Advisory engagements.

Power increasingly lies with the companies that control our access to customers, information and payments. A business may depend on Instagram for visibility, Google for enquiries or a payment provider to collect its income. When those companies change their rules, the consequences can be immediate. How much control do you have over your business if someone else controls your access to customers?
