The Green Blood of America
This text explains how a fungus carried to Ireland by American cargo ships led to the “Great Potato Famine” in Europe and triggered one of the largest waves of migration to the U.S.
The “Golden Age” of mass immigration through the Port of New York took place between 1895 and 1914. At that time, the main source of migration was Europe, with the first large wave of immigrants coming from Ireland. They left their homeland to escape famine, which became known as the “Great Potato Famine.” This migration resulted in the arrival of about 1 million Irish people in the U.S., nearly one-sixth of the island’s total population at that time.
Although the period known as the “Little Ice Age” was coming to an end, the cold and excessive rain of that time created perfect climatic conditions for the Great Potato Famine to occur. The direct cause of this catastrophe was a fungus known as Phytophthora infestans, commonly referred to as potato blight. This fungus was accidentally brought to Europe by cargo ships from North America, and found in Ireland the ideal environment to multiply explosively and decimate the crops.
In addition to the cold, damp weather at that time, the Irish custom of growing a single variety of potato—the Irish Lumper—which was replanted using pieces of potatoes harvested the previous year, contributed to the catastrophe. This resulted in potato crops that were genetically identical to one another, like perfect clones. Consequently, when the fungus attacked the crops, there was not a single resistant plant in the entire country.
This potato variety was the only one capable of producing large quantities of food in the poor, rocky soils occupied by the island’s Catholic peasants, and it constituted nearly the entirety of the average Irish adult’s staple diet. They consumed, on average, 4 to 6 kilograms of potatoes per day, mixed with a little water and milk. The population’s dependence on this crop was so great that, when the blight struck the harvest, the census recorded a decline of nearly 20% in the population over ten years. One million people died of starvation, while another million Irish fled the country to escape poverty.
However, the situation these immigrants encountered in the United States was not much better. Having emigrated to the U.S. without money to buy land or travel to the interior, they were concentrated near the ports of entry, in the cities of New York and Boston, surviving in miserable conditions.
They were viewed with suspicion by the local Protestant population because of their allegiance to the Pope, and were considered alcoholics, violent, and biologically inferior. The appalling living conditions in New York’s tenements and the lack of employment resulted in an average life expectancy of 6 years after their arrival on the American continent.
It took decades for these immigrants to escape poverty. This eventually happened thanks to the efforts of the Catholic Church, which built a vast network of schools, hospitals, and orphanages to provide a social safety net. In addition, the Irish gained broad access to education and learned to vote as a bloc, taking control of the New York Democratic Party.
In the decades that followed, waves of immigrants from Germany, Italy, and the Russian Empire would arrive in the U.S.
