? Especially geographical conditions, will directly affect the cultural differences in Europe. The average elevation in Europe is the lowest among the seven continents, only 340 meters, and the area below 200 meters accounts for more than 60% of the total area. It will be colder at low altitude and there will be more cold air, so the noses of Europeans have evolved to adapt to this weather.
More than one third of the total area of Europe is peninsulas and islands, of which peninsulas account for nearly one third. Europe is near the sea, and there are many peninsulas and islands, so Europe is divided into different regions, and then each region develops independently, with different cultures and religions. Different regions have developed into different races because there are too many blocks and too many races. Unlike our country, it was ruled by Manchu and later by Han. This is because there are many Han people in our country. Although there are many races in Europe, no region can surpass other races, so there can be no major ethnic groups with overwhelming population in Europe.
After the industrial revolution, Britain and other marginal countries were unwilling to unify Europe and tended to expand abroad. Although Britain does not want to unify Europe, its position cannot be shaken by other countries. As long as you oppose Britain, you will lose your colony. Today's Britain is much worse than Britain after the industrial revolution, but it still wants to leave Europe and does not want to take the lead with Germany and France. If Germany and France can't do it in Britain, then the two will do it together.
Why Europe can't be unified is because they all want to go abroad after they become strong, and they don't want to unify Europe.
