Reading may have originated as a Roman settlement on the River Thames or at an intersection of Roman roads. It is first mentioned in the 8th century as Readingum and was the site of the first Battle of Reading in 871. The founding of Reading Abbey in 1121 increased the town's prosperity, though the relationship between the abbey and the townspeople was sometimes strained. The abbey was largely destroyed during the Dissolution of the Monasteries in 1538. Reading grew into an important market town and manufacturing center over subsequent centuries.
