The Irish Potato Famine
During the summer of 1845, a
"blight of unusual character"
devastated Ireland's potato crop,
the basic staple in the Irish diet.
A few days after potatoes were
dug from the ground, they began
to turn into a slimy, decaying,
blackish "mass of rottenness."
The cause was a fungus that had
traveled from Mexico to Ireland.
"Famine fever – a variety of
diseases-soon spread through the
Irish countryside. Observers
reported seeing children crying
with pain and looking "like
skeletons, their features sharpened
with hunger and their limbs
wasted, so that there was little left
but bones." Masses of bodies were
buried without coffins, a few inches
below the soil.
Over the next ten years,
more than 750,000 Irish died
and another 2 million left
their homeland for Great
Britain, Canada, and the
United States. Within five
years, the Irish population
was reduced by a quarter.
Irish peasants subsisted on a
diet consisting largely of
potatoes, since a farmer could
grow triple the amount of
potatoes as grain on the same
plot of land. A single acre of
potatoes could support a family
for a year. About half of Ireland's
population depended on potatoes
Tenant farmers held short-term
leases that were payable each six
months in some areas. If the tenants
failed to pay their rent, they were
jailed or evicted and their homes
burned. During the time of the Great
Hunger (1845-1847), approximately
500,000 people were evicted, many
of whom died of starvation or disease
or relocated to mismanaged and
inadequate poor houses.
The alternative to eviction,
poorhouses, or starvation was
emigration, which rose to over two
million people from 1845-1855.
Emigrants tended to follow their
families which were found mostly in
Great Britain, United States, Canada,
New Zealand, and Australia.
There were two ways out of this Irish
nightmare, death and emigration.

Reasons for Migration
On each of the following
slides make a list of things
that pushed and pulled
people to move.
Many people migrate to be closer
to their family and friends. It
gives them a familiar feeling in a
new place. When immigrants
came to the United States, they
often moved near family or
friends. This eventually led to
entire neighborhoods full of one
People often migrate to live in a
climate that lets them live how
they want. The climate affects
what crops can grow, what animals
can be bred, and even what kind
of house can be built. Some people
even migrate with the seasons,
living up north during the summer
and in the south during the winter,
to have more temperate climates
People migrate to an area to
live near natural resources they
need or want. They can use
these natural resources to help
them survive and trade them
for other things they do not
have. Middle Eastern countries
are near oil, and they can trade
it with other countries for
things they do not have, like
timber and types of food.
People also migrate to an area
because of job opportunities.
As cities grow, more people are
migrating into them from the
country to have better and
more jobs. People also migrate
to different countries to get
better jobs at higher wages.
