Bacon's goals were threefold: discovery of truth, service to his country, and service to the church. Knowing that a prestigious post would aid him toward these ends, in 1580 he applied, through his uncle,
Lord Burghley, for a post at court which might enable him to devote himself to a life of learning. His application failed, and for the next two years he worked quietly at Gray's Inn giving himself seriously to the study of
law, until admitted as an
outer barrister in 1582. In 1584 he took his seat in
parliament for
Melcombe in
Dorset, and subsequently for
Taunton (1586). He wrote on the condition of parties in the church, and he wrote down his thoughts on philosophical reform in the lost tract,
Temporis Partus Maximus, but he failed to obtain a position of the kind he thought necessary for his own success.
In the Parliament of 1586 he took a prominent part in urging the execution of
Mary Queen of Scots. About this time he seems again to have approached his powerful uncle, the result of which may possibly be traced in his rapid progress at the bar, and in his receiving, in 1589, the reversion to the Clerkship of the
Star Chamber, a valuable appointment, the enjoyment of which, however, he did not enter into until 1608.
During this period Bacon became acquainted with
Robert Devereux, 2nd Earl of Essex (1567–1601),
Queen Elizabeth's favorite. By 1591 he was acting as the earl's confidential adviser. Bacon took his seat for
Middlesex when in February 1593 Elizabeth called a Parliament to investigate a
Roman Catholic plot against her. His opposition to a bill that would levy triple subsidies in half the usual time (he objected to the time span) offended many people; he was accused of seeking popularity, and was for a time excluded from the court. When the
Attorney-Generalship fell vacant in 1594 and Bacon became a candidate for the office, Lord Essex's influence could not secure him the position; in fashion, Bacon failed to become
solicitor in 1595. To console him for these disappointments, Essex presented him with a property at
Twickenham, which he subsequently sold for £1800, the equivalent of around £240,000 today.
In 1596 he was made a
Queen's Counsel, but missed the appointment of
Master of the Rolls. During the next few years, his financial situation remained bad. His friends could find no public office for him, a scheme for retrieving his position by a marriage with the wealthy widow Lady
Elizabeth Hatton failed, and in 1598 he was arrested for debt. His standing in the queen's eyes, however, was beginning to improve. He gradually acquired the standing of one of the learned counsel, though he had no commission or warrant and received no salary. His relationship with the queen also improved when he severed ties with Essex, a fortunate move considering that the latter would be executed for treason in 1601; and Bacon was one of those appointed to investigate the charges against him, and examine witnesses, in connection with which he showed eagerness in pressing the case against his former friend and benefactor. This act Bacon endeavoured to justify in
A Declaration of the Practices and Treasons, etc., of ... the Earl of Essex, etc. He received a gift of a fine of £1200 on one of Essex's accomplices.
The accession of
James I brought Bacon into greater favour; he was knighted in 1603, and endeavoured to set himself right with the new powers by writing his
Apologie (defence) of his proceedings in the case of Essex, who had favoured the succession of James. Bacon was present at the state opening of parliament in 1605, which would have all but certainly made him a victim of the
Gunpowder Plot had it succeeded. The following year, during the course of the uneventful first parliament session Bacon married
Alice Barnham.
In 1608, Bacon entered upon the Clerkship of the
Star Chamber, and was in the enjoyment of a large income; but old debts and present extravagance kept him embarrassed, and he endeavoured to obtain further promotion and wealth by supporting the king in his arbitrary policy. However, Bacon's services were rewarded in June 1607 with the office of Solicitor. In 1610 the famous fourth parliament of James met. Despite Bacon's advice to him, James and the Commons found themselves frequently at odds over royal prerogatives and the king's embarrassing extravagance, and the House was dissolved in February 1611. Through this Bacon managed in frequent debate to uphold the prerogative, while retaining the confidence of the Commons. In 1613, Bacon was finally able to become
attorney general, by dint of advising the king to shuffle judicial appointments; and in this capacity he would prosecute
Somerset in 1616. The parliament of April 1614 objected to Bacon's presence in the seat for
Cambridge — he was allowed to stay, but a law was passed that forbade the attorney-general to sit in parliament — and to the various royal plans which Bacon had supported. His obvious influence over the king inspired resentment or apprehension in many of his peers.
Bacon continued to receive the King's favour, and in 1618 was appointed by James to the position of
Lord Chancellor. His public career ended in disgrace in 1621 when, after having fallen into debt, a Parliamentary Committee on the administration of the law charged him with corruption under twenty-three counts. To the lords, who sent a committee to inquire whether the confession was really his, he replied, "My lords, it is my act, my hand, and my heart; I beseech your lordships to be merciful to a broken reed." He was sentenced to a fine of £40,000, remitted by the king, to be committed to the
Tower of London during the king's pleasure (his imprisonment in fact lasted only a few days). More seriously, Lord St Alban was declared incapable of holding future office or sitting in parliament. He narrowly escaped being deprived of his titles. Thenceforth the disgraced viscount devoted himself to study and writing.
It has been argued by
Nieves Mathews that Bacon was in fact innocent of the
bribery charges; Bacon himself claimed he was forced to plead guilty so as to save King James from a political scandal, stating:
I was the justest judge, that was in England these last fifty years. When the book of all hearts is opened, I trust I shall not be found to have the troubled fountain of a corrupt heart. I know I have clean hands and a clean heart. I am as innocent of bribes as any born on St Innocents Day.
