The English Civil War of 1642, between Parliamentarians and Royalists vying for the power to govern, ended in a short-lived republic under Oliver Cromwell until King Charles 11 was restored to the throne. Casualty estimates for military and disease deaths indicate England suffered a 3.7% loss of population, Scotland a loss of 6%, while Ireland suffered a loss of 41% of its population.
The devastation is clearest on the England 11 May 973 AD chart with the natal Sun Mars square Pluto having moved by Solar Arc to collide with the England Saturn; and both the Solar Arc Neptune and transiting Neptune were hitting on the England Pluto which also pulled in hard aspects to the England Sun Mars – a perfect storm of military brutality, extreme hardship and mass devastation and confusion.
The England 25 December 1066 chart had Solar Arc Mars opposition Pluto; with tr Uranus exactly square the 1066 Mars.
The traditional civil war signature is tr Pluto conjunct the Sun which was in place for the break up of the USSR, though it wasn’t exactly a war. Tr Pluto was also square the Russia Saturn then.
Syria in 2015 when the civil war erupted had a tr Pluto square tr Saturn which often accompanies a war; with tr Pluto heading to conjunct the Syria Capricorn Sun as it got fully underway; and Solar Arc Neptune hovering around the opposition to the midpoint between the Syria Saturn and the Syria Mars Uranus conjunction. Uranus had just moved into Aries preparing for the rebellious square to Pluto in the next few years.
British India 1 January 1877 12am Delhi, at the bloody partition with Pakistan in 1947 which led to 14 million being displaced and well over one million dead did have a tr Mars Uranus in place in August 47 though it’s a minor enough aspect. Tr Uranus was square the India Solar Arc midheaven for a sharp change of direction. The Solar Arc Pluto had been in the devastating/confused square to the India Neptune in the run up; and the Solar Arc North Node was exactly conjunct Pluto pulling on the Fixed Pluto opposition Mars square Uranus T Square.
Usually it takes more than one influence to catapult a country into civil breakdown. The USSR break up happened at the time of the triple conjunction in Capricorn. The 1848/1850s upheavals all over Europe and elsewhere also occurred on a triple conjunction of Uranus Pluto Saturn in Aries, then moving together into Taurus, so quite a whammy. Indian partition happened around the bleak Saturn Pluto in Leo; the Syrian Civil War on Uranus square Pluto.
The USA had tr Pluto conjunct its Cancer Sun in the early 1920s and showed no sign of fragmenting. The UK had tr Pluto conjunct the Capricorn Sun in the run up to the Scotland Independence Referendum so it was a possibility. The USA won’t get tr Uranus conjunct its Mars until 2030 – and those Uranian hard aspects occur roughly every twelve years, so it’s been through a few since 1776. The UK gets tr Uranus conjunct its Mars around 2021.
No real conclusions except that its much like individuals, you can never quite gauge from the swirling cycles of differing influences what will prove a tipping point or indeed how the reactions will manifest. Some stand steady in the eye of the hurricane; some don’t.
