Or did tensions continue to persist?
Not really,
After 1815 , the two countries were never at war with each other. There was , of course, tension : the question of Belgian independence in 1831 , the crisis in Syria in 1840 or the complex case of the Spanish marriages in 1846 and recurring " invasion scares " ( psychoses invasion ) each once France pretended to have a navy worthy of the name .
But Guizot minister of Foreign Affairs from 1840 to 1848 , was a strong Anglophile , both as Orléanist and as a Protestant , and he served in the diplomatic rapprochement of the 1840s known as the " entente cordiale " , symbolized by the meetings between the young Victoria and Louis -Philippe , King of the French (1843 , 1844 , 1845) .
The reign of Napoleon III , convinced himself of British superiority and the need for France to get to the English school to accelerate its economic development , and saw the signing of a free trade agreement (Cobden -Chevalier) .
The defeat of France against the Germans in 1870-1871 marked in the eyes of Britain the end of the threat of French hegemony on the continent, and soon the German danger would have seemed much more significant - especially when William II wanted to provide the country a marine in line with the Weltpolitik it had set as a goal. We know how this naval question definitively blurred the two countries and hastened the conclusion of the Entente Cordiale in 1904, six years after the Fashoda crisis, an epic national humiliation for France, epiphenomenon quickly forgotten in Britain. From the 1910s, , the staffs of the two countries began to develop joint projects, while psychoses invasion now taking German as a target .
