Answer:
German Americans
Explanation:
The greatest flow of German immigration to America occurred between 1820 and the First World War, during which almost six million Germans emigrated to the United States. From 1840 to 1880, they were the largest immigrant group. Following the revolutions of 1848 in the German states, a wave of political refugees fled to the United States, which became known as Forty-Eighters (those of '48 in English). Among them professionals, journalists and politicians. Prominent Forty-Eighters included Carl Schurz and Henry Villard.
Although these people quickly became familiar with the American way of life and culture, during the First World War they were subject to acts of discrimination because of their nationality and the rivalry that was taking place in the war on European territory.
