Committee appointed for the purpose, it was Somers who drew up the
Declaration of Right, which, in placing the Prince and Princess of
Orange on the throne, set forth the grounds of the Revolution and
asserted against royal encroachment the ancient rights and liberties of
England. For these services and for his rare ability as a constitutional
lawyer, King William, in the first year of his reign, made Somers
Solicitor-General. In 1692 he became Attorney-General as Sir John
Somers, and soon afterwards, in March 1692-3, the Great Seal, which had
been four years in Commission, was delivered to his keeping, with a

1697 Somers as Lord Keeper delivered up the Great Seal, and received it
back with the higher title of Lord Chancellor. He was at the same time
created Baron Somers of Evesham; Crown property was also given to him to

and deprived him of office, but they failed before the Lords in an
impeachment against him. In Queen Anne's reign, between 1708 and 1710,
