This question projects backwards labels that do not apply to the mid-seventeenth century. The creation of Whig and Tory parties date to the 1670s and 1680s, not the 1640s or 1650s. Older histories have sometimes found in the Parliamentarians the origins of the Whig party, but it has since been shown that the people who split along Royalist / Parliamentarian lines did not map onto Tory / Whig party ideologies in the 1680s and onward. Tories were thought to be members of the King's court - his nobles, advisers, privy councilors, while the country members were lawyers, JPs, and MPs. Those divisions did not make sense before the Restoration, as Royalists commonly came from the Country in the west and south, Parliamentarians from London and the North. Both sides maintained that they were of the Church of England, neither group had to decide the issue of Royal exclusion because there was no Catholic heir, etc. (Keeler, The Long Parliament, 1640-1641: A Biographical Study of Its Members; Plumb, The Growth of Political Stability in England, 1675-1725).
