In the early 19th century, the Irish arrived in Cleveland in search of opportunity. Construction on the Ohio and Erie Canal in 1825 attracted many Irish seeking employment. After the canals were completed, many who survived grueling labor conditions left northeastern Ohio, but others became dockworkers and shipbuilders. The Irish who made Cleveland home impacted the city significantly. The Roman Catholic Church became a mainstay for Irish immigrants, and parochial schools offered Irish youth an education steeped in faith and knowledge. Irish pride is evident by enthusiastic participation in clubs, festivals, cultural organizations, and public service. Irish Americans are now one of the largest and most active of the many ethnic groups represented in Cleveland, as demonstrated by the much-anticipated and well-attended annual St. Patrick’s Day parade.
