In March 1660 the Long Parliament finally dissolved itself, and elections were held for the Convention Parliament, which sat in May. This body, dominated by royalists and Presbyterians, formally proclaimed Charles II as king, and he was restored to the throne on 29 May 1660. In order to minimise acts of reprisal and vengeance for acts taken during the Interregnum, the parliament passed the Indemnity and Oblivion Act, under whose terms most actions were forgiven. Specific exceptions were made for those directly involved in the regicide. Although Vane didn't support the regicide and wouldn't take an oath of support for it afterwards, after long debate, Vane was also named as an exception. The act was not passed until August 1660, and Vane was arrested on 1 July 1660 on the orders of the king and imprisoned in the Tower of London. The parliament, after passing the Indemnity Act, petitioned Charles to grant clemency to Vane and others, asking that his life might be spared. This petition was granted.
