People immigrate for many reasons, some of which include economic or political reasons, family reunification, natural disasters, or the desire to change one's surroundings. Immigration can represent an expansion of the supply of labor in the host country.
immigration affected immigrants and other Americans around the year 1900 is after the depression of the 1890s, immigration jumped from a low of 3.5 million in that decade to a high of 9 million in the first decade of the new century. Immigrants from Northern and Western Europe continued coming as they had for three centuries, but in decreasing numbers. After the 1880s, immigrants increasingly came from Eastern and Southern European countries, as well as Canada and Latin America. By 1910, Eastern and Southern Europeans made up 70 percent of the immigrants entering the country. After 1914, immigration dropped off because of the war, and later because of immigration restrictions imposed in the 1920s. (did that answer your question?)
Yes, it was. The Treaty of Versailles made Germany take full responsibility for World War I, even though the war was the fault of multiple countries. It also made Germany pay extensive war debts to pay for the damages of the war, which completely destroyed Germany's economy with inflation. The Treaty of Versailles also severely limited Germany's military, which was very important to them. So Germany's response to the Treaty of Versailles was legitimate due to the severe punishments inflicted on Germany which were very harsh for a war that they did help initiate, but were not completely at fault for.
