Hunger marches are a form of social protest that arose in the United Kingdom during the early 20th century. Often the marches involved groups of men and women walking from areas with high unemployment, to London where they would protest outside parliament. Sometimes they would march instead to the offices of regional authorities in cities closer to home. Protesters would try to make the point that lack of work meant they were unable to buy sufficient food to prevent themselves and their families from hunger. The first such march took place in 1905. The term "hunger march" was coined three years later in 1908. In the first two decades of the 20th century, there was relatively little unemployment in the UK, but it could still become a severe problem in various areas after disruptive changes to the local economy. Hunger marches became much more prominent in the 1920s and 1930s during the Great Depression in the United Kingdom.
During the worldwide Great Depression of the 1930s, hunger marches also began to appear in other countries such as Canada. Many of the UK hunger marches were supported by the British wing of the Communist party. While communism was at this time far more respectable than it was to become after the Cold War, this still often caused authorities to regard hunger marches with hostility. The marches were often brutally oppressed, and by the late 20th century had been mostly forgotten. An exception is the Jarrow crusade. This march had fewer than five hundred participants, with religious rather than political overtones. It did not provoke a hostile response from the authorities and was therefore nonviolent. Michael Portillo has said this caused the Jarrow march to be well-regarded and remembered, in contrast to the other marches which often had tens of thousands of participants and had a greater impact.
In the decades that followed World War II, there was much less unemployment in the UK and throughout the industrialized world, due in part to the Keynesian revolution. Even those without work or savings found it easier to feed themselves, due to the establishment of the welfare state. As a result, hunger marches were no longer needed. There were incidences where thousands of people embarked on marches to draw attention to hunger in the developing world, as happened for example during the 1973 Ethiopian famine, but the term "hunger march" was not often used to describe these events.
