In 1631 Oliver sold his paternal estate in Huntingdon and managed a rented farm at St. Ives for five years; then he removed to Ely, in the fen country, and again took up farming, being joined by his mother and sisters. He served in the great Parliament which passed the Petition of Right, but played no part of prominence therein: standing stoutly, however, for Puritanism and Parliamentary freedom. During the ensuing eleven years of unrest, while all England was making ready for the impending conflict, Oliver busied himself with his farm and his family. He showed himself one of the strongest bulwarks of the Puritan preachers; zealous in the endeavor to further the cause of religion in every way, and always open to appeals from the poor and the oppressed, of whom he was the consistent champion. When certain rich men, headed by the Earl of Bedford, endeavored to oust from some of their rights the poor people of the fens, Oliver headed the latter in their resistance. He was keenly interested in the trial of his kinsman, John Hampden, for refusal to pay the Ship Money; a trial which was managed by the advocate Oliver St. John, his cousin by marriage. In short, Cromwell was far more concerned in righting specific cases of oppression than in advancing the great principles of constitutional government which alone make possible that orderly liberty which is the bar to such individual acts of wrong-doing. From the stand-point of the private man this is a distinctly better failing than is its opposite; but from the stand-point of the statesman the reverse is true. Cromwell, like many a so-called “practical” man, would have done better work had he followed a more clearly defined theory; for though the practical man is better than the mere theorist, he cannot do the highest work unless he is a theorist also. However, all Cromwell’s close associations were with Hampden, St. John, and the other leaders in the movement for political freedom, and he acted at first in entire accord with their ideas: while with the religious side of their agitation he was in most hearty sympathy.
