William Monson, 1st Viscount Monson (died c. 1672)[1] was one of the Regicides of King Charles I of England.[2][3]
Monson was knighted in 1623 and created Viscount Monson of Castlemaine (Irish peerage) in 1628. He was elected M.P. for Reigate in 1640, 1645 and 1648. He was nominated as one of the king's judges, but only attended three sittings. After the Restoration of the monarchy in 1660, he was sentenced by Parliament to degradation from his honours and titles and to be imprisoned for life. He died in the Fleet Prison in around 1672.[2][3]
