Nativism: Nativism refers to the policy or ideology that promotes the interests of native-born citizens over those of immigrants. During this time, nativist sentiments grew as some Americans feared competition for jobs and resources from Irish immigrants.
Tenements: Tenements were overcrowded apartment buildings where many poor Irish immigrants lived. These cramped living conditions often lacked proper sanitation and contributed to disease outbreaks.
Know-Nothing Party: The Know-Nothing Party was an American political party formed by nativists during the mid-nineteenth century. They opposed immigration and sought stricter naturalization laws, particularly targeting Catholic immigrants like many Irish individuals.
