Irish Canadians
The first waves of Irish immigrants took place between 1763 and 1880. when ten thousand Irish immigrants arrived on the Island. From 1800 to 1850, "10,000 immigrants from every county in Ireland" had settled in Prince Edward Island and represented 25% of the Island population by 1850.
Irish Americans
Since the arrival of nearly two million Irish immigrants in the 1840s, the urban Irish police officer and firefighter have become virtual icons of American popular culture. In many large cities, the police and fire departments have been dominated by the Irish for over 100 years, even after the ethnic Irish residential populations in those cities dwindled to small minorities. Many police and fire departments maintain large and active "Emerald Societies", bagpipe marching groups, or other similar units demonstrating their members' pride in their Irish heritage.
