Discuss the main consequences of the Great Famine.

I assume you mean the Great Irish Famine caused by the
failure of the potato crop between 1845-1852. The famine was caused by potato blight, a
disease which destroyed the potato crop. Since potatoes require a great deal of time to
mature, once the damage was done, it was too late to plant another crop. The
consequences included starvation and death, emigration, and eviction, and
revolt.

Since potatoes were a staple in the Irish diet,
many people died either of starvation of illnesses related to malnutrition. Estimates of
the death toll vary from 500,000 to over one million. Many died from cholera, caused by
drinking contaminated water.

Roughly one million people
left Ireland during the famine, many of whom emigrated to the United States and Canada.
Most who emigrated were younger members of families who wished for a new beginning. They
generally settled in large cities, such as Boston and Philadelphia, eventually becoming
a substantial portion of those cities' population.

Aside
from starvation, many emigrated because they were evicted by their landlords. Many
people were not eligible for public assistance, and since landlords were taxed for the
land, they evicted poorer tenants with abandon. Many tenants did not take kindly to
eviction, and several landlords were murdered by angry
tenants.

Finally, a rebellion broke out in 1848. The
rebellion failed, and most of the leaders were exiled to Tasmania off the coast of
Australia.
