Much of O'Casey's work, particularly his early plays, focuses on nationalist themes. He made his public debut when ''The Shadow of a Gunman'' was performed at [[Dublin|Dublin's]] [[Abbey Theater]] in 1923. This was followed by his two most critically acclaimed plays, ''Juno and the Paycock'' in 1924 and ''The Plough and the Stars'' in 1926, both also put on by the Abbey. The latter was misunderstood by audiences as being anti-nationalist, and generated unrest similar to [[John Millington Synge|Synge's]] ''Playboy of the Western World'' 19 years earlier.
Upset at the rejection of his next play, ''The Silver Tassie'', in 1929 O'Casey broke with the Abbey and moved to [[England]], where he lived until his death. His plays during this time were more explicitly socialist but did not meet with the same critical or box office success as his early works. O'Casey died of a [[heart attack]] at the age of 84.<ref>[httphttps://www.nytimes.com/learning/general/onthisday/bday/0330.html Obituary in the ''New York Times'']</ref>
