When the fleet bearing Margaret of Denmark and the Scottish ambassadors arrived in
Leith, the king's sister, Mary, wife of the Earl of Arran, informed her husband that the king was planning to have him arrested, and the couple fled together to Denmark by sea, and then to
Bruges, where they were soon joined by Lord Boyd, who fled there from England. At a Parliament held in November, Lord Boyd, his brother, Sir Alexander, and the Earl of Arran, were all found guilty of
treason and their peerages were forfeited. Sir Alexander was condemned to death and beheaded. James III married 13-year-old Margaret of Denmark in July 1469 at
Holyrood Abbey,
Edinburgh, in a service overseen by Archibald Crawford, the
Abbot of Holyrood. The marriage produced three sons:
James, Duke of Rothesay,
James, Duke of Ross, and
John, Earl of Mar. James III began his personal rule in 1469, yet his exercise of royal power was affected by the fact that he was one of the few Stewart monarchs who had to contend with the problem of an adult, legitimate brother. In 1469, James had two surviving younger brothers,
Alexander, Duke of Albany, and
John, Earl of Mar, then aged fourteen and about twelve, and three Stewart half-uncles (the earls of
Atholl and
Buchan, and the
Bishop of Moray), and each of them would complicate the politics of the reign. From the positive beginnings after his assumption of active control of government in 1469, James III's relationship with Parliament would lead to opposition, criticism, and outright confrontation over his foreign and domestic policies. The failure of the king to listen to the grievances raised by the three estates, or to abide by the concessions he made to them, were significant causes of the two major rebellions in 1482–1483 and 1488.
Foreign schemes and alliance with England James's policies during the early 1470s revolved primarily around ambitious continental schemes to emphasize the prestige of the king and the Stewart dynasty, expand the territory under James's rule, and agree to an alliance with England. The main business of the parliament James III called in 1471 was the granting of a tax to fund an embassy to the continent to allow him to act as arbitrator between
Charles the Bold,
Duke of Burgundy, and
Louis XI of France. The embassy would also seek a
Burgundian or French marriage for the king's sister,
Margaret. In February 1472, James's second continental scheme saw him ask Parliament to fund his plan to lead an army of 6,000 men to assert his tenuous claim to the
Duchy of Brittany, which derived from his aunt,
Isabella. Parliament granted a tax of £5,000 to fund the sending of this army to the continent as part of a Franco-Scottish invasion against
Francis II, Duke of Brittany, though protests by the clergy about the king leading an army abroad while he had no issue to succeed him eventually led to James abandoning his plans for an invasion of Brittany. In April 1473, the battle of succession for
Guelders between James's grandfather,
Arnold, Duke of Guelders, and his son
Adolf, provided the king with another continental scheme. The deposition of Arnold by his son in 1465 and his reinstatement at the hands of Charles the Bold in 1471 had left Arnold wishing to alter the succession to prevent the duchy falling to either his son or the Duke of Burgundy. In 1472, he asked James or one of his brothers to travel to Guelders and take possession of the duchy. Duke Arnold died in February 1473, and with him, any serious likelihood of putting his succession plans into effect, but James III was undaunted and sent an ambassador to Charles the Bold to press his claim. James also sent ambassadors to France offering military aid to Louis XI against England in return for a pension of 60,000 crowns a year. In addition, James sought to reassert his father's claim to the French province of
Saintonge, a claim which dated back to the Treaty of Perth-Chinon between
James I of Scotland and
Charles VII of France, when the province was offered to the Scottish king in return for an army of Scottish troops which were never sent. In October 1474, James III concluded a truce with
Edward IV of England which was intended to (but did not) last for forty-five years and was to be accompanied by a marriage alliance between James's heir, the infant
Duke of Rothesay, and Edward's daughter,
Cecily of York, when both of them reached marriageable age. The prospective bride's dowry was 20,000 marks sterling, which would be paid in advance in annual instalment of 2,000 marks over a period of seventeen years. On 20 February 1472, Parliament brought the negotiations, which had begun with the Treaty of Copenhagen, to an end by annexing and uniting the
earldom of Orkney and the lordship of Shetland to the Scottish Crown. In theory, Christian I of Denmark or his successors could still redeem the islands by paying the balance of Queen Margaret's dowry, but in practice, with Christian's continuing financial difficulties and the strong control the Scottish Crown exercised over Orkney and Shetland, this was highly unlikely. James would continue to press for English alliances for the rest of his reign, although he also sought a marriage alliance with
Mary of Burgundy for his brother Albany in 1477 and renewed the Franco-Scottish alliance with
Charles VIII of France in 1484. The confrontation began in September 1475, when John was accused of a number of offences against the Crown, including treasonable dealings with England and the Earl of Douglas and besieging
Rothesay Castle. When John did not appear for trial before Parliament in December, he was declared forfeit. The Lord of the Isles appeared before the king in Edinburgh in July 1476, and the forfeiture was rescinded. The earldom of Ross was annexed to the Crown,
Kintyre,
Knapdale, and the offices of
sheriff of
Inverness and
Nairn were lost, and the Lord of the Isles was reduced to a mere
Lord of Parliament. On the day of the forfeiture of the Lord of the Isles, James III had Parliament approve his
act of revocation. The king stood at the height of his power, having removed the Boyds, annexed Orkney and Shetland, humbled the Archbishop of St Andrews, agreed to peace and an alliance with England, and forfeited the Lord of the Isles. Complaints from Parliament that royal justice was not being actively administered by the king in person occurred throughout his reign, partly due to his practice of delegating responsibility to appointed justices and allowing Ayres to be held without his presence. In May 1479, Albany was accused of
treason for arming and provisioning
Dunbar Castle against the king, assisting known rebels and deliberately causing trouble on the
Anglo-Scottish border in violation of the truce between Scotland and England. In 1478, James proposed strengthening the alliance with England still further by offering his sister Margaret as a bride for Edward IV's brother-in-law,
Anthony Woodville, 2nd Earl Rivers. Soon afterwards, however, the truce began to break down, with several instances of Scottish cross-border raiding and pillaging. In 1480, Edward IV sent an envoy to Edinburgh with what was essentially a
declaration of war, informing James that the English king intended to wage war against the Scots unless these demands were met: that the Scots make reparations for breaches of the truce; that James return Berwick, Roxburgh and Coldingham to English dominion; and that James do homage to Edward for the Scottish Crown. However, Edward was prepared to maintain the peace if James would surrender Berwick and hand over his son and heir as a guarantee of his intention to carry through with the marriage of the Duke of Rothesay and Cecily of York. By October, James III had written to
Louis XI of France asking for guns and artillerymen to repulse further attacks. The spring and autumn of 1481 saw English ships raid the
Forth, attacking
Blackness Castle and harassing shipping. There does not seem to have been a land-based invasion of Scotland, but there were three raids into England by a Scottish army in that year. Edward IV had made invasion preparations and began to travel north, but went no further than
Nottingham. In 1482, Edward IV launched a full-scale invasion led by the Duke of Gloucester, the future
Richard III. James's brother Alexander, styled "Alexander IV", was included as part of the invasion party. James, in attempting to lead his subjects against the invasion, was arrested by a group of disaffected nobles at
Lauder Bridge in July 1482. It has been suggested that the nobles were already in league with Alexander. The king was imprisoned in
Edinburgh Castle, and a new regime, led by "lieutenant-general" Alexander, became established during the autumn of 1482. Meanwhile, the English army, unable to take
Edinburgh Castle, ran out of money and returned to England, having
taken Berwick-upon-Tweed for the last time. == Restoration to power ==
