Conditions in Ireland were not as good as in the rest of the UK. Two-thirds of the population still depended on farming to make their living, often on very small plots of land. Many depended on potatoes as a large part of their died. In the middle of the century the potato crop failed, and Ireland suffered a famine. A million people died from disease and starvation. Another million and a half left Ireland. Some emigrated to the United States and others came to England. By 1861 there were large populations of Irish people in cities such as Liverpool, London, Manchester and Glasgow.
The Irish Nationalist movement had grow strongly though the 19th century. Some, such as the Fenians, favored complete independence. Other, such as Charles Stuart Parnell, advocated 'Home Rule', in which Ireland would remain in the UK but have its own parliament.
