The House of Lords rejected the second Reform Bill in October 1831, stalling long-sought electoral reform. Public anger was further inflamed when Charles Wetherell, a judge known for opposing reform, arrived in Bristol on 29 October to open the assizes, drawing large hostile crowds.
Protests against Wetherell's arrival degenerated into three days of rioting from 29 to 31 October 1831. Civic and military authorities failed to coordinate an effective response, losing control of the city centre. Much of the centre was burnt, causing up to £300,000 in damage and around 250 casualties before a middle-class posse comitatus and military forces finally restored order.
Mayor Charles Pinney was tried for neglect of duty but acquitted, while military commander Lieutenant-Colonel Brereton faced court-martial and died by suicide before its conclusion. The riots intensified pressure on Parliament, contributing to the passage of the Great Reform Act in 1832 and, locally, to municipal reform under the Municipal Corporations Act 1835.
Political Outcome
Order restored after three days; Great Reform Act passed 1832; municipal reform followed via Municipal Corporations Act 1835
Unreformed electoral system; House of Lords blocking Reform Bill
Great Reform Act 1832 introduced sweeping electoral changes; Bristol municipal government reformed by 1835
