Margaretta Ruth D’Arcy, Irish actress, writer, playwright, and activist, is born in London on June 14, 1934. She has been a member of the Irish association of artists, known as Aosdána, since its inauguration and is known for addressing Irish nationalism, civil liberties, and women’s rights in her work.

D’Arcy is born to a Russian-Jewish mother and an Irish Catholic father. She works in small theatres in Dublin from the age of fifteen and later becomes an actress.

D’Arcy is married in 1957 to English playwright and author John Arden. They write several plays together which are highly critical of the British presence in Ireland. They settle in Galway in 1971 and establish the Galway Theatre Workshop in 1976. The couple has five sons, one of whom predeceases his mother.

The couple writes a number of stage pieces and improvisational works for amateur and student players, including The Happy Haven (1960) and The Workhouse Donkey (1964). She writes and produces many plays, including The Non-Stop Connolly Show (1977).

D’Arcy has also written a number of books, including Tell Them Everything (1981), Awkward Corners (with John Arden, 1988), and Galway’s Pirate Women: A Global Trawl (1996).

As an activist, in 1961, D’Arcy joins the anti-nuclear Committee of 100, led by Bertrand Russell. In 1981, her peace-activism results in her incarceration in Armagh Jail, after defacing a wall at the Ulster Museum. Her book Tell Them Everything (Pluto Press, 1981) tells the story of her time during the Armagh and H-Block dirty protests and is one of the earliest accounts about the Armagh women, their republicanism and imprisonment.

D’Arcy also directs Yellow Gate Women (2007), a film about the attempts by women of Greenham Common Women’s Peace Camp to outwit the British and United States military at RAF Greenham Common with bolt cutters and legal challenges. Challenging censorship since 1987, she runs a women’s kitchen pirate radio from her home in Galway.

In 2011, D’Arcy refuses to stand for a minute’s silence to honour Police Service of Northern Ireland (PSNI) officer Ronan Kerr, killed by dissident republicans, at an Aosdána meeting. Her actions are deliberate, she tells the media afterwards, which attracts fierce criticism of her perceived support for armed republican groups in Northern Ireland.

Along with Niall Farrell, D’Arcy is arrested in October 2012 for scaling the perimeter fence of Shannon Airport, in protest at the use of the airport as a stopover for U.S. military flights. As a consequence of her trespassing on airport property, she is imprisoned in 2014 after she refuses to sign a bond saying that she will not trespass on non-public parts of Shannon Airport.
