Charles O'Conor
Charles O'Conor (1710–1791) was born into the O'Conor Don family of Roscommon, direct descendants of the kings of Connacht. He lived through the Penal Laws, when Irish Catholics had almost no legal rights. Despite this, he became one of Ireland's finest historians and antiquarians. He published Dissertations on the History of Ireland in 1766—the first serious attempt by an Irishman to study and write Irish history in centuries. He co-founded the Catholic Committee and became a member of the Royal Irish Academy. He did this quietly, in a small house in the Irish countryside, during a time when being learned and Irish was dangerous.
