United States has a past strongly marked by immigration. A century ago, another important migratory wave came from Europe between 1890 and 1919. At that time, most came from Germany, although the United Kingdom, Canada and Italy also contributed their share.
By 1910, German immigrants in the US represented no less than 18% of the total, or the equivalent of some 2,5 million people. In addition, the Germans were the largest migrant group in 17 states of the country and in the district of Columbia, unlike what happened with Mexicans, who were the majority only in three states: Arizona, New mexico and Texas.
