A hunger strike is a method of non-violent resistance in which participants fast as an act of political protest, or to provoke a feeling of guilt in others, usually with the objective to achieve a specific goal, such as a policy change. Most hunger strikers will take liquids but not solid food.
In cases where an entity (usually the state) has or is able to obtain custody of the hunger striker (such as a prisoner), the hunger strike is often terminated by the custodial entity through the use of force-feeding.
Early history
Fasting was used as a method of protesting injustice in pre-Christian Ireland, where it was known as Troscadh or Cealachan. Detailed in the contemporary civic codes, it had specific rules by which it could be used. The fast was often carried out on the doorstep of the home of the offender. Scholars speculate that this was due to the high importance the culture placed on hospitality. Allowing a person to die at one's doorstep, for a wrong of which one was accused, was considered a great dishonor. Others say that the practice was to fast for one whole night, as there is no evidence of people fasting to death in pre-Christian Ireland. The fasts were primarily undertaken to recover debts or get justice for a perceived wrong. There are legends of Saint Patrick, the patron saint of Ireland, using the hunger strike as well.
In India, the practice of a hunger protest, where the protester fasts at the door of an offending party (typically a debtor) in a public call for justice, was abolished by the government in 1861; this indicates the prevalence of the practice prior to that date, or at least a public awareness of it.
Medical view
In the first three days, the body is still using energy from glucose. After that, the liver starts processing body fat, in a process called ketosis. After depleting fat, the body enters a "starvation mode". At this point the body "mines" the muscles and vital organs for energy, and loss of bone marrow becomes life-threatening. There are examples of hunger strikers dying after 46 to 73 days of strike, for example the 1981 Irish hunger strike. Hunger strikers can experience hallucinations and delirium.
Death usually occurs when a hunger striker has lost about 40–50% of their pre-strike weight and at about 60–70 days in. Obese individuals can last longer.
Examples
British and American suffragettes
In the early 20th century suffragettes frequently endured hunger strikes in British prisons. Marion Dunlop was the first in 1909. She was released, as the authorities did not want her to become a martyr. Other suffragettes in prison also undertook hunger strikes. The prison authorities subjected them to force-feeding, which the suffragettes categorized as a form of torture. Emmeline Pankhurst's sister Mary Clarke died shortly after being force-fed in prison, and others including Lady Constance Bulwer-Lytton are believed to have had serious health problems caused by force feeding, dying of a heart attack not long after. William Ball, a working class supporter of women's suffrage, was the subject of a pamphlet Torture in an English Prison not only due to the effects of force-feeding, but a cruel separation from family contact and mental health deterioration, secret transfer to a lunatic asylum and needed lifelong mental institutional care. In December 1912, a Scottish prison put four suffragettes in the 'political prisoner' category rather than 'criminal' second division, but staff at Craiginches Prison, Aberdeen still subjected them to force-feeding when they went on hunger strike.
In 1913 the Prisoners (Temporary Discharge for Ill Health) Act 1913 (nicknamed the "Cat and Mouse Act") changed policy. Hunger strikes were tolerated but prisoners were released when they became sick. When they had recovered, the suffragettes were taken back to prison to finish their sentences. About 100 women received medals for hunger striking or enduring force-feeding.
Like their British counterparts, American suffragettes also used this method of political protest. A few years before the passage of the Nineteenth Amendment to the United States Constitution, a group of American suffragettes led by Alice Paul engaged in a hunger strike and endured forced feedings while incarcerated at the Occoquan Workhouse in Virginia.
