What was one of the main reasons that large numbers of irish moved to the united states in the 18405?

Potato Blight

Explanation:

Ireland’s 1845 Potato Blight is often credited with launching the second wave of Irish immigration to America. The fungus which decimated potato crops created a devastating famine. Starvation plagued Ireland and within five years, a million Irish were dead while half a million had arrived in America to start a new life. Living conditions in Ireland were deplorable long before the Potato Blight of 1845, however, and a large number of Irish left their homeland as early as the 1820s.

the results of roman expansion produced social conflict and civil war. julius caesar gained power and became a dictator but was then assassinated. the reign of augustus began a long period of imperial rule and peace in the roman empire. rome faced the problems of how to maintain peace, law, and order.
