again to colonize Ireland fearing another rebellion in Ulster, using previous colonial Irish endeavours as their influence. King James would succeed Queen Elizabeth the I, because King James I was previously King James VI of Scotland, he would plant both English and Scottish in the plantations of Ulster drawing upon the Munster Plantations, this proved to be the most successful they were settled in what's mostly Now Northern Ireland. The Plantations of Ireland introduced Tudor English settlers to Ireland, while The Plantation of Ulster in the 17th century introduced a great number of Scottish and to a lesser extent English as well as French Huguenots as colonists. All previous endeavours were solely an English venture. The Lord Protector Oliver Cromwell (1653–1658) after the defeat of the Irish rebels would also plant New English in Ireland, known as the Protestant ascendency. Enlightenment Ireland There have been notable Irish scientists. The Anglo-Irish scientist Robert Boyle (1627–1691) is considered the father of chemistry for his book The Sceptical Chymist, written in 1661. Boyle was an atomist, and is best known for Boyle's Law. The hydrographer Rear Admiral Francis Beaufort (1774–1857), an Irish naval officer of Huguenot descent, was the creator of the Beaufort scale for indicating wind force. George Boole (1815–1864), the mathematician who invented Boolean algebra, spent the latter part of his life in Cork. The 19th century physicist George Stoney introduced the idea and the name of the electron. He was the uncle of another notable physicist, George FitzGerald. The Irish bardic system, along with the Gaelic culture and learned classes, were upset by the plantations and went into decline. Among the last of the true bardic poets were Brian Mac Giolla Phádraig (c. 1580–1652) and Dáibhí Ó Bruadair (1625–1698). The Irish poets of the late 17th and 18th centuries moved toward more modern dialects. Among the most prominent of this period were Séamas Dall Mac Cuarta, Peadar Ó Doirnín, Art Mac Cumhaigh, Cathal Buí Mac Giolla Ghunna, and Seán Clárach Mac Domhnaill. Irish Catholics continued to receive an education in secret "hedgeschools", in spite of the Penal laws. A knowledge of Latin was common among the poor Irish mountaineers in the 17th century, who spoke it on special occasions, while cattle were bought and sold in Greek in the mountain market-places of Kerry. For a comparatively small population of about 6 million people, Ireland made an enormous contribution to literature.
