In Munster, during the peaceful early years of the 17th century, thousands more English and Welsh settlers arrived in the province. There were many small plantations in Munster in this period, as Irish lords were required to forfeit up to one third of their estates to get their deeds to the remainder recognised by the English authorities. The settlers became concentrated in towns along the south coast – especially Youghal, Bandon, Kinsale and Cork city. Notable English Undertakers of the Munster Plantation include Walter Raleigh, Edmund Spenser, and Richard Boyle, 1st Earl of Cork. The latter especially made huge fortunes out of amassing Irish lands and developing them for industry and agriculture.
