Career
Parliament of Ireland
Boyle was educated at Winchester College. He represented the borough of Clonakilty in the Irish Parliament from 1793 until 1797 and then Cork County from 1797 until the Act of Union in 1801. In 1798, he was also elected for Rathcormack, however chose not to sit. According to his obituary in The Gentleman's Magazine, Boyle "took an active part in arming the yeomanry in Ireland." On 31 October 1796 Boyle was commissioned Captain of five different units, those of Castlemartyr, Cloyne, Cove, Imokilly and Middleton. At the time the Kingdom of Great Britain and the Kingdom of Ireland were under personal union. The Yeomanry were volunteer regiments raised in many counties from yeomen. Their purpose was to strengthen the defence of the two Kingdoms which faced the threat of an invasion by the French First Republic.
The Irish Rebellion of 1798 was assisted by a French invasion force under Jean Joseph Amable Humbert. The rebellion and the invasion failed. To secure control of Ireland, the Parliament of Ireland and the Parliament of Great Britain negotiated a merger of the two kingdoms. The Act of Union 1800 resulted in the formation of the United Kingdom of Great Britain and Ireland. The final passage of the Act in the Irish Parliament was achieved with substantial majorities, achieved in part, according to contemporary documents, through bribery, in the form of peerages and honours to critics to get their votes. Whereas the first attempt had been defeated in the Irish House of Commons by 109 votes against to 104 for, the second vote in 1800 produced a result of 158 to 115. By agreement, Ireland gained 100 seats in the British House of Commons and 32 seats in the House of Lords: 28 representative peers elected for life, and four clergymen of the (Anglican) Church of Ireland, chosen for each session.
