and for those who are too lazy to go to the site
Anti-Irish racism includes persecution, discrimination, hatred or fear of the Irish as an ethnic or national group, whether directed against 
Ireland in general or against Irish immigrants and their descendants in the 
diaspora particularly in the early days. It is traditionally rooted in the 
Irish and 
English relationship and their views of each other and is also evidenced in Irish immigration to other countries like the 
United States in the early days.
The term also applies to the 
religious persecution of Irish Roman Catholics.
19th century
Anti-Irish racism in Victorian Britain and 19th century United States included the 
stereotyping of the Irish as 
alcoholics,
and implications that they monopolized certain (usually low-paying) job
markets. Similar to other immigrant populations, they were sometimes
accused of 
cronyism, and subjected to misrepresentations of their religious and cultural beliefs. 
Catholics were particularly singled out, and indigenous 
folkloric and 
mythological beliefs and customs were ridiculed.
[3] Nineteenth century Protestant American "
Nativist" prejudice against Irish Catholics reached a peak in the mid-1850s with the 
Know Nothing Movement, which tried to oust Catholics from public office. Much of the opposition came from Irish 
Protestants, as in the 1831 riots in 
Philadelphia, Pennsylvania.
[4]
In rural areas in the 1830s riots broke out among rival labor teams
from different parts of Ireland, and between Irish and "native"
American work teams competing for construction jobs.
[5]
It was common for Irish people to be discriminated against in social
situations, and intermarriage between Catholics and Protestants was
uncommon (and strongly discouraged by both ministers and priests). One
response to this prejudice was the creation of a parochial school
system, in addition to numerous colleges, that isolated about half the
Irish youth from the public schools.[

After 1860 many Irish sang songs about signs reading "HELP WANTED - NO
IRISH NEED APPLY"; these signs came to be known as "NINA signs." (This
is sometimes written as "IRISH NEED NOT APPLY" and referred to as "INNA
signs"). These songs had a deep impact on the Irish sense of
discrimination.

The 1862 song, "No Irish Need Apply", was inspired by NINA signs in London. Later the song was adapted by 
Irish Americans to include their experiences as well. The issue of job discrimination against Irish immigrants to 
America
is a hotly debated issue among historians, with some insisting that the
"No Irish need apply" signs so familiar to the Irish in memory were
myths, and others arguing that not only did the signs exist, but that
the phrase was also seen in print ads and that the Irish continued to
be discriminated against in various professions into the 20th century.
[6]
Whether or not the signs ever existed in large numbers, many New
Yorkers and other Americans harbored Nativist sentiment against the
Irish Catholic poor in the post-Civil war period. Irish Americans were
effectively barred from certain occupations. While the Irish dominated
such occupations as domestic service, building, and factory work, they
were not present in large numbers in the professions, finance, and
other "white collar" businesses. Irish people are stereotyped for
violence. Since many of the earliest late 19th century immigrant
population was Irish, they received the first attacks and
discrimination by Nativists and Protestants.
