The correct answer is "Irish Catholic residents."
The Philadelphia Nativist Riots of 1844 began because of Irish Catholic residents.
The mid-1800s was a difficult time for immigrants in the United States.
Among the many incidents of those years, the Philadelphia Nativist Riots of 1844 made the news in the Pennsylvania region.
These riots involved serious aggressions to Catholic Irish in the area of Philadelphia. The riots started on May 6-8, 1844, and continued two months later on July 6-7, the same year. The specific places of the riots were the neighborhoods of Southwark and Kensington.
Local people were tired of the presence of Irish-Catholic in the city and the riots started. The fight increased to the degree that the state government had to send troops to stop the fights and control the situation. There were many casualties and some people died.
