Just for fun. The old enmity between England and France stretches back a millennium, with wiki listing 22 wars between the two countries and that was only from 1200 onwards till the early 19th Century; so not including the Norman invasion of 1066.
The England 11 May 973 JC AD chart probably works best. That has a Taurus Sun Mars square Pluto in Leo which collides mightily with the France 21 September 1792 chart with its Uranus in Leo opposition Pluto in Aquarius square Mars in Scorpio – both fixed, utterly unyielding and vengeful nations. The England 973 AD chart also has Saturn in Gemini which squares the France 1792 Virgo Sun.
That relationship chart is even worse than the France/UK one with a composite Pluto trine Sun and square Neptune; as well as Pluto opposition Saturn square Mars – they don’t come much worse than that. Implacable hostility.
Even the France 10 August 843 chart with its Leo Sun hitting the England Sun Mars and Pluto; and the France Mars in Gemini square Pluto crashing into the England Saturn in Gemini is no better and makes obvious why there were centuries of fighting. That relationship chart has a bitter, power-struggling Mars Pluto sextile Mars, trine Uranus and opposition Neptune.
The surprise is that hostilities ceased on the battlefield at all; and that the UK laid itself on the line in two world wars in the 20th Century in an alliance with France against invasions from Germany.
