Born in Rhode Island, Arthur Browne was a lawyer, a scholar and a politician in the Ireland of the late 18th century, where he established a brilliant reputation in all three areas at a time of enormous conflict and upheaval. The pre-eminent maritime lawyer of his era, Browne was also an MP in the Irish parliament, and the Regius Professor of Civil and Canon Law at Trinity College Dublin, where he has been described as ‘one of the most able and learned academic lawyers ever to teach there.’ A brilliant and forceful debater, Browne opposed violent revolution, supported the Catholics, and became one of the most powerful liberal voices in the Irish parliament in the 1790s. His international reputation as a legal scholar was established by his two-volume study on the civil law and the law of the admiralty in 1797 and 1799, a work that had a major influence around the world and especially with American maritime law. This new book explores how the American-born Browne became a leading figure in Irish law, academic and politics, and it provides an entirely new perspective on his role in parliament during the controversial passing of the Act of Union in 1800.
