 Thousands of Germans and Irish from the southern regions of their countries immigrated to the United States during the 19th century and were met with strong opposition from the majority Protestant and temperance movement-minded Old Stock, who were anti-immigration and anti-Catholic.Regardless of ancestral origin, English-speaking, native-born White Americans, were referred to as Anglos or Native Americans (not to be confused with Indigenous Americans).American settlers arriving in droves to the newly acquired, formerly French Louisiana, Spanish Florida, and Mexican colonies (Texas, New Mexico with Arizona, California), whether they were native born or of European origin, were labelled as "Anglos”.
