This is a very interesting video about the history of great empires – the rise and fall over time. What interested me was the understanding of a 500 year cycle and a 250 year cycle.
In astrology, the Pluto cycle is 248 years and the Neptune cycle is 164 years. Pluto and Neptune have the longest cycles. They are both frequently used in understanding cycles and systems globally. These 2 planets come together in a very long 493 to 500 year cycle. You will see these 2 time bands being used to explain the rise and fall of the great empires from the Dutch to the British and then the USA.
We are in a period of extraordinary change with 3 outer planets changing signs – Pluto into Aquarius – last in this sign between 1777 and 1798. This cycle started again in 2023 and ends in 2044. This is the 248 year cycle. Back in history, this cycle was associated with US independence and French Revolution.
Neptune is now moving into Aries – last in this sign between 1861 and 1875. This cycle started again in 2025 and ends in 2039. This in the 164 year cycle. This cycle was associated with the abolishment of slavery in the US.
The Neptune Pluto that we are currently in started in 1890’s. It will conclude in 2385. We are not going to witness the end of this period! The core themes are associated with collective beliefs, myth and power structures. What does a civilisation believe in and who controls that belief?
Pluto is always associated with power/control/death/decay.
Neptune is always associated with dreams/ideals/spiritual path/deception/illicit activities like drugs and alcohol and the oceans/shipping/navy/ports.
The stress points in the cycle will come with the 0/90/180 degree aspects.
- Neptune conjunct Pluto – 1891 to 1892 – degrees 7/8 Gemini – mass persuasion and ideological empires.
- Neptune waxing square Pluto – 2061 to 2065 – degrees 23 to 28 Gemini/Pisces – crisis of trust in global system.
- Neptune opposed Pluto – 2137 to 2141 – degrees 7 to 14 Sagittarius/Gemini – two world views in open conflict
- Neptune waning square Pluto – 2309 to 2312 –degrees 24 to 29 Sagittarius/Pisces – dissolution of outdated belief systems.
- Neptune conjunct Pluto – 2385 – 12 Gemini – new collective myth.
This can be summarised as humanity’s long journey from mass illusion to mass awakening to a rewritten collective dream.

These planets will now form a sextile (60 degree aspect) between Jul 2026 and Feb 2032 – degrees 4 to 14 Aries/Aquarius. They have been in sextile before from 1950 to 1956 – the National Party came into power in 1948. Another sextile between 1976 to 1986. Certainly these were turbulent times in SA especially the more recent period of 1976 to 1986 which signalled the end of Apartheid.
Uranus will be moving into Gemini between 2025 and 2033. Uranus was last in Gemini between 1941 and 1949 – WW2 and the establishment of United Nations, NATO, World Bank and IMF. It is this post WW2 order that is currently under threat. Uranus will trigger the conjunction degrees of 7/8 Gemini in 2028.
