From the Tudor to Georgian periods farming specialised and the monastic estates broke up, leading to an increase in population and settlement size. The Dissolution of the Monasteries closed the abbeys at Sherborne, Shaftesbury, Milton Abbas, Abbotsbury and Cerne Abbas, though both Sherborne and Milton abbeys were saved from destruction. In 1588, eight ships from Dorset assisted in the destruction of the Spanish Armada. The flagship San Salvador still lies at the bottom of Studland bay. Sir Walter Raleigh later settled in Sherborne and served as MP for Dorset.
