Which of the following factors significantly contributed to Irish immigration to America?

The significant factor that contributed to Irish immigration to America was the English oppression and the potato famine. During the mid-19th century, Ireland faced a devastating potato blight that resulted in widespread famine from 1845 to 1852, causing mass starvation and suffering. In addition to the famine, many Irish people were driven to leave their homeland due to English oppression, which included harsh economic policies and a lack of political rights for the Irish population. This combination of dire economic conditions and oppressive rule created a desperate situation in Ireland, prompting millions to seek a better life in the United States.

The large influx of Irish immigrants during this period had lasting effects on American society, culture, and demographics, leading to significant changes, including the formation of vibrant Irish communities and the introduction of Irish culture into the American mainstream. By contrast, factors such as economic prosperity in Ireland, religious freedom in America, and the desire for luxury goods did not serve as primary motivators for migration during the critical period of the Irish diaspora.
