Corbet’s political life lies mainly beyond the scope of these volumes as he did not become active in either local or national affairs until after 1628, when his elder brother Sir John, one of the ‘Five Knights’, died as a result of being imprisoned by the king. John’s death may ultimately have influenced Corbet to become a staunch parliamentarian during the Civil War.
An active lawyer, Corbet was returned to the 1628 Parliament as the junior burgess for Great Yarmouth, where he was recorder.
Corbet became an important Member of the Long Parliament, was a founding member of the Eastern Association, and later signed the death warrant of Charles I. Appointed a commissioner for Irish affairs in 1650, he lived in Ireland during the 1650s, becoming chief baron of the Irish Exchequer in 1655. After the Restoration, he was elected for Great Yarmouth to the Convention Parliament, but his return was annulled. Fearing retribution for his part in the regicide, Corbet fled to the Continent, but was captured in Holland by Sir George Downing† and brought to England, where he was tried and condemned to death.
