1870, London, England was in the Victorian era, which was the heyday of Britain. Europe was very turbulent this year, because Prussia occupied Paris in the Franco-Prussian War, French culture and civilization, and all European fashions were transferred to London at once. ....

1870 June is also the year when Dickens, a great English writer, died, amid the noise of London. London has splendid urban buildings, and the urban poor with dirty sewage live in slums!

French impressionist painters Monet and pissarro both came to London as refugees. 1870, Monet was 30 years old and pissarro was 40 years old.

They stayed until the end of the second year. In Paris, France, which was open at that time, impressionist painting was easily recognized and accepted by the public. London, which is relatively conservative, is not enthusiastic about Impressionism, which is one reason why many Impressionist paintings later flowed to the United States.
