After the failure of the revolt of his cousin, Henry Stafford, 2nd Duke of Buckingham, Henry VII became the leading Lancastrian contender for the throne of England. Having gained the support of the in-laws of the late Yorkist King Edward IV, he landed with a force in Wales and marched into England, accompanied by his uncle, Jasper Tudor. Wales had traditionally been a Yorkist stronghold, and Henry owed the support he gathered to his ancestry, being directly descended, through his father, from the Lord Rhys. He amassed an army of around 5000 soldiers and travelled north. There his Lancastrian forces decisively defeated the Yorkists under Richard III at the Battle of Bosworth Field in 1485 when several of Richard's key allies switched sides or deserted the field of battle. This battle effectively ended the long-running Wars of the Roses between the two houses. Henry's claim to the throne was tenuous and based upon a lineage of illegitimate succession. However, this was no barrier to the Throne; inheritance was not the sole method of becoming Sovereign. Claims could also be based on nomination (by the previous Sovereign), statute, prescription (de facto possession of power) and, as was the case with Henry VII, conquest.
The first of Henry's concerns on attaining the monarchy was the question of establishing the strength and supremacy of his rule. There were few other claimants to the throne left alive after the long and bloody civil war, so his main worry was pretenders such as Perkin Warbeck, who were backed by disaffected nobles. Henry succeeded in securing his crown by a number of means but principally by dividing and undermining the power of the nobility.
Henry's first action was to declare himself king as-of the day before the battle, thus ensuring that anyone who had fought against him would, technically, be guilty of treason. It is interesting to note, therefore, that he spared Richard's designated heir, John de la Pole, Earl of Lincoln. He would have cause to regret his leniency two years later, when Lincoln rebelled and attempted to set a boy pretender, Lambert Simnel, on the throne in Henry's place. Lincoln was killed at the Battle of Stoke, but Simnel's life was spared and he became a royal servant.
Simnel had been put forward as "Edward VI", impersonating the young Edward, Earl of Warwick, son of George, Duke of Clarence, who was still imprisoned in the Tower of London. Henry had shown uncharacteristic leniency in dealing with Edward and did not find a pretext for executing him until he had grown into adulthood, in 1499. Edward's elder sister, Margaret Pole, who had the next best claim on the throne, inherited her father's earldom of Salisbury and survived well into the next reign.
Another method Henry used to secure his throne was to carry out his promise to marry Elizabeth of York, daughter and heir of King Edward IV. The marriage took place on January 18,1486 at Westminster. This unified the warring houses, and gave him a greater claim to the throne due to Elizabeth's line of descent (though there is evidence that Edward was born illegitimate).

Economic and diplomatic policies
Henry was a fiscally prudent monarch who restored the fortunes of an effectively bankrupt exchequer (Edward IV's treasury had been emptied by his wife's Woodville relations after his death and before the accession of Richard III) by introducing efficiently ruthless mechanisms of taxation. In this he was supported by his chancellor, Archbishop John Morton, whose "Morton's Fork" (the two "tines" of which being: those who had previously paid little could therefore afford to pay more, those who had paid much before could obviously afford therefore to pay yet more) was a catch 22 method of ensuring that nobles paid increased taxes. Royal government was also reformed with the introduction of the King's Council that kept the nobility in check.
Henry's policy was both to maintain peace and to create economic prosperity. Up to a point, he succeeded in both. He was not a military man, and had no interest in trying to regain the French territories lost during the reigns of his predecessors; he was therefore only too ready to conclude a treaty with France that both directly and indirectly brought money into the coffers of England. He had been under the financial and physical protection of the French throne or its vassals for most of his career as a pretender prior to his ascending to the throne of England. To strengthen his position, however, he subsidized shipbuilding, thus strengthening the navy and improving trading opportunities. By the time of his death, he had amassed a personal fortune of a million and a half pounds; it did not take his son as long to fritter it away as it had taken the father to acquire it.
In 1502, fate dealt Henry a double blow from which he never fully recovered: His heir, the recently-married Arthur, died in an epidemic at Ludlow Castle and was followed only a few months later by Henry's queen, in childbirth. Not wishing the negotiations that had led to the marriage of his elder son to Catherine of Aragon to go to waste, he arranged a dispensation for his younger son to marry his brother's widow â€” normally a degree of relationship that precluded marriage in the Roman Catholic Church. Henry obtained a dispensation from Pope Julius II but had second thoughts about the value of the marriage and did not allow it to take place during his lifetime. Although he made half-hearted plans to re-marry and beget more heirs, these never came to anything. On his death in 1509, he was succeeded by his second son, Henry VIII.
