Even among Europeans, those not considered white at some time in American history include Southern Europeans (Spaniards, Greeks, Italians etc.), Irish Catholics, Eastern Europeans and Germans. Early on in the United States, white generally referred to those of British Isles or northwestern European descent.
Irish and Africans Americans had lots in common and lots of contact during this period; they lived side by side and shared work spaces. In the early years of immigration the poor Irish and blacks were thrown together, very much part of the same class competing for the same jobs. In the census of 1850, the term mulatto appears for the first time due primarily to inter-marriage between Irish and African Americans. The Irish were often referred to as "Negroes turned inside out and Negroes as smoked Irish." A famous quip of the time attributed to a black man went something like this: "My master is a great tyrant, he treats me like a common Irishman." Free blacks and Irish were viewed by the Nativists as related, somehow similar, performing the same tasks in society. It was felt that if amalgamation between the races was to happen, it would happen between Irish and blacks.
