in the
British Museum Cotton supported the claim of King
James VI of Scotland to succeed Queen
Elizabeth I on the English throne, and after the queen's death was commissioned to write a work defending James's claim to the throne, for which he was rewarded with a knighthood in 1603. Cotton was elected to Parliament for
Huntingdonshire in 1604, a constituency previously represented by his grandfather,
Thomas Cotton. Cotton worked on the Committee on Grievances and in 1605–06 received the Bill pertaining to the
Gunpowder Plot through his work on the Committee of Privileges. In 1607 he was reappointed to the Committee of Privileges. Cotton was appointed to the joint conference with the
House of Lords during his work on the bill pertaining to the full union between Scotland and England in 1606–07. In 1610, Cotton was nominated in first place to the Committee of Privileges. In 1610/11 the royal revenues were low, and Cotton wrote
Means for raising the king’s estate in which he suggested the formation of the
baronetcy, a new order of social rank, higher than the knight but lower than the baron. Cotton was not elected to the 1614 Parliament. In 1621, Cotton advised James I on the impeachment of
Sir Francis Bacon concerning the respective roles of the king and Parliament. In 1624, Cotton was elected to represent
Old Sarum after the previous member,
Sir Arthur Ingram, decided to sit for
York. He was subsequently elected to Parliament for
Thetford (1625) and
Castle Rising (1628). ==Society of Antiquaries==
