By 1525, Reading was the largest town in Berkshire, and tax returns show that Reading was the 10th largest town in England when measured by taxable wealth. By 1611, it had a population of over 5000 and had grown rich on its trade in cloth, as instanced by the fortune made by local merchant John Kendrick. Reading played an important role during the English Civil War. Despite its fortifications, it had a Royalist garrison imposed on it in 1642. The subsequent Siege of Reading by Parliamentary forces succeeded in April 1643. The town’s cloth trade was especially badly damaged, and the town’s economy did not fully recover until the 20th century. Reading played a significant role during the Revolution of 1688: the second Battle of Reading was the only substantial military action of the campaign. The 18th century saw the beginning of a major iron works in the town and the growth of the brewing trade for which Reading was to become famous. Reading’s trade benefited from better designed turnpike roads which helped it establish its location on the major coaching routes from London to Oxford and the West Country. In 1723, despite considerable local opposition, the Kennet Navigation opened the River Kennet to boats as far as Newbury. Opposition stopped when it became apparent that the new route benefited the town. After the opening of the Kennet and Avon Canal in 1810, one could go by barge from Reading to the Bristol Channel. From 1714, and probably earlier, the role of county town of Berkshire was shared between Reading and Abingdon. During the 19th century, the town grew rapidly as a manufacturing centre. The Great Western Railway arrived in 1841, followed by the South Eastern Railway in 1849 and the London and South Western Railway in 1856. The Summer Assizes were moved from Abingdon to Reading in 1867, effectively making Reading the sole county town of Berkshire, a decision that was officially approved by the privy council in 1869. The town became a county borough under the Local Government Act 1888. The town has been famous for the Three Bs of beer (1785-2010, Simonds Brewery), bulbs (1837-1974, Suttons Seeds), and biscuits (1822-1976, Huntley and Palmers).
