Which London knight and mayor helped suppress the Peasants' Revolt by killing Wat Tyler in 1381?

The London knight and mayor who helped suppress the Peasants' Revolt by killing Wat Tyler in 1381 was William Walworth.

Walworth was a wealthy London fishmonger, alderman, and civic official who became Lord Mayor of London. During the revolt, rebels led by Wat Tyler entered London and met King Richard II at Smithfield on 15 June 1381.

Contemporary accounts state that Walworth attacked Tyler during the meeting after a confrontation. Tyler was then seized and fatally wounded, while Richard II addressed the rebels and promised reforms before the uprising collapsed.

The revolt had begun in response to taxation, labor controls, and wider social tensions following the Black Death. Walworth’s role made him a prominent royal supporter, and Richard II knighted him after the crisis. Accounts differ in some details of the confrontation, but Walworth’s identification is consistent in standard historical references.
