What effect did the world war have on people from Germany and people from Britain?

Both WW1 and WW2 killed a lot of people in both countries (soldiers and civilians), and cost them a lot of money. A good part of the cities of both countries were destroyed. After WW2, Germany lost the right to govern itself, and was divided into 2 countries. For many ears after the war, the residents of Germany were governed by one of the Allied countries that defeated Germany.
