2.1 Background
The Wars of the Roses were the longest period of civil war in English history 1455- 1499. They occurred following the final English defeat in the Hundred Years' War, (1337-1453) and were a series of wars, minor clashes, and disorders between two branches of the Plantagenet family, Lancaster and York. There were three periods of sustained conflict: 1459-61, 1469-71, and 1483-87.
It all began with king Edward III. He had seven sons, but it was the descendants of three of them, Lionel Duke of Clarence 2nd surviving son; John Duke of Lancaster 3rd surviving son; and Edmund Duke of York 4th surviving son; which were to change the course of history. Edward III was succeeded by his eldest son the ill fated Richard II, who was deposed by Henry IV, who was the son of the Duke of Lancaster. There was therefore a 'Lancastrian' king of England, as was his son the victor of Agincourt Henry V and his son Henry VI.
Hostilities began under the rule of the Lancastrian King Henry VI (1422-1461, who became king at just 9 months old after the untimely death of his father Henry V (1413-22). Until he was old enough to rule, England was run as a protectorate.  He was the youngest prince to succeed the throne of England and the only one to be crowned twice as dual Monarch for England and France. He grew up under the tutelage of Richard Beauchamp Earl of Warwick but proved to be a weak and ineffectual king; he displayed a lack of apptitude for, or interest in, military and perhaps, political matters, and prone to give credence to ill judged, unsuitable advice and counsel.  A continuation of poorly selected advisors and councillors culminated in 1450 when Edmund Beaufort 2nd duke of Somerset became principal councillor. Somerset had for the last few years prior, been deeply involved losing every important town and province in France won by the much-lamented Henry V, and by August 1450, all of Normandy had been lost, with some remnants of Gascony only, remaining. A further 12 months saw even that gone, and only the port of Calais remaining under the English crown. The country was brimming with disaffected soldiery and nobility, and the resulting poverty of some of the fighting classes led to a renewed stirring of 'Livery and Maintenance', the by then illegal loyalties of lesser nobles and their tenants to their more powerful neighbours. Obssessionally religious, he became known as the 'cleric-in-kings-clothing'. He had a brief period of instability between 1453-54 which has been interpreted in modern times as a bout of catatonic schizophrenia.
The country was starting to polarise. In 1445, Henry married Margaret of Anjou, a French noblewoman of keen ambition and impeccable heritage. She greatly favoured the inept Somerset and his Beaufort family over more reliable men. One such was Richard Duke of York who was descended from Edward III by Lionel Duke of Clarence his 2nd son. York was not popular with the queen, he had a direct bloodline to Edward III, which was at least as good as her husband's, and some said, better. So rather than keep York onside, he was marginalised with the Lieutenancy of Ireland. However, civil unrest in England, which resulted in the revolt of Jack Cade and the men from Kent, fired York to action. What with all English influence in France gone, and the threat of civil disorder, the country appeared to be descending into a pit of chaos. York had however been excluded from the royal council, and had no means of asserting any of his considerable power for the country or king's benefit. The animosity between York and Somerset was palpable. Both had huge wealth and power, and as the antagonism grew, so did the certainty of civil war. By 1453, matters had come to a head, the king was disabled with mental illness which lasted for 15 months, Somerset had been impeached, and was locked up in the Tower of London, and the queen, who had been childless for 8 years, was then heavily pregnant. Parliament needed a regent to take control, and with the prevailing circumstances, they decided to appoint York as Protector and Defender of the Realm. By the end of 1454, the king had recovered his mental faculties, and immediately set about undoing everything that York had done, including restoring Somerset to full power and authority. The Duke of York retired in indignation to his castle and estates at Wakefield and Sandal in Yorkshire. In the middle of May 1455, York had gathered to his cause sufficient numbers of nobles and men to attempt to resolve things by force of arms, and at the head of 3,000 men, began the march south, towards war.

The loss of English territories in France and Henry's ineffectiveness to govern, led Richard Duke of York (d.1460) to call for reforms.  Inevitably this led to conflict between the two sides, Lancaster and York. In 1459 a sustained conflict began, and Henry was defeated and exiled.  The Yorkists under Warwick the Kingmaker returned triumphant in 1460 to promote the Duke of York's claim to the Crown. On the 10th of October 1460 parliament passed an act of settlement which recognised Richard, Duke of York as heir to Henry VI, thus excluding Henry's son Edmund, Prince of Wales (Richard's claim to the throne was a legitimate one and had more credence than Henry's). This didn't go down too well with the nobility and especially with Henry's Queen, Margaret of Anjou. More politically astute than her feeble minded husband, she already had a deep- seated hatred for York and Warwick and had the support of some of the nobles.  She summoned the Dukes of Exeter, Somerset, Devon, Clifford, Roos, Greystoke and Latimer to join her with their forces in the north of England. Thus began the most violent phase of the conflict, which would end in 1461 at the battle of Towton.
After parliament declared for Richard in October 1460, Margaret of Anjou had raised a substantial army in the north. Concerned about such a concentration of Lancastrian forces in Yorkshire Richard marched north with Lord Salisbury to Sandal castle near Wakefield recruiting as he went. As to what happened at Wakefield is something of a mystery, but on the 30th of December 1460 a large Lancastrian force lured the Yorkists out of the castle (one suspects treachery) and defeated them. Richard was killed during the battle and his 17-year-old son Edmund Earl of Rutland was murdered by Lord Clifford on Chantry Bridge. Lord Salisbury was taken prisoner and executed at Pontefract Castle the next day. The heads of York, Rutland and Salisbury were to adorn the walls of Micklegate Bar in York; the Duke's wearing a paper crown. After Wakefield the Lancastrian army began to move south towards London, plundering and pillaging as they went.
York's nineteen-year-old son Edward Earl of March had been celebrating Christmas at Shrewsbury when he heard about the deaths of his father and brother. He immediately moved to intercept the Lancastrian forces before they reached London but was confronted by a Lancastrian Force under the command of the Earls of Pembroke and Wiltshire at Mortimers Cross on the 2 February 1461, he won a decisive victory and took prisoner Owen Tudor (the Grandfather of Henry VII, the victor at Bosworth in 1485), who was executed the next day. After another battle at St Albans and the fact that the citizens of London had closed the gates, the Lancastrians moved back north, soon to be followed by the newly proclaimed Edward IV at the head of a powerful army, which would meet an equally powerful Lancastrian army on Towton Dale. So the scene was set for one of the bloodiest episodes in English history.
England was at war with its self, or more accurately, the English nobility was at war with them selves. The so-called Wars of the Roses (a name not conjured up until centuries later by Sir Walter Scott) were, in their simplest terms, conflicts between two branches of the royal line. It is easiest to call them the houses of York and Lancaster, not to be confused with either county shire of those names. The wars spanned in all, 35 years, during of which there were fought as many battles as there were years. It was during those battles that ancient family scores could be settled, causing new outbursts of hatred and fury.
Although Edward of York had initially been reluctant to proclaim himself king, his heavy defeat at the second Battle of St. Albans convinced him that he needed to take that final, irrevocable step of rebellion. No sooner had the dust settled on that defeat than Edward was acclaimed king in London.
Meanwhile, instead of following up his triumph at St. Albans with a decisive march on the capital, Henry VI opted for caution and withdrew his men north. The actual decision to pull back was probably Henry's, though he was easily led, particularly by his strong- willed queen, Margaret of Anjou.
So the Lancastrians withdrew to their power base in the north, probably destroying as they did so their only real hope of a quick end to the conflict. Edward IV threw caution aside, quickly raised a fresh army, and pushed north on his enemy's heels. He caught up with them near the river Aire, where both armies spent the night on the cold, snowy ground.
The Battle of Towton took place on March 29, 1461 at Towton, Yorkshire. It involved the Yorkist army under Edward IV vs. Lancastrian forces led by the Duke of Somerset on behalf of Henry VI and Queen MargaretThe Battle of Towton in the Wars of the Roses was the bloodiest ever fought on British soil, with casualties believed to have been in excess of 20,000 (perhaps as many as 30,000) men. The battle took place on a snowy 29 March 1461 (Palm Sunday) on a plateau between the villages of Towton and Saxton in Yorkshire (about 12 miles southwest of York and about 2 miles south of Tadcaster).
Part of the reason so many died is perhaps because in the parley before the battle both sides agreed that no quarter would be given nor asked.
It is thought that 50,000, or perhaps even 100,000 men fought, including 28 Lords (almost half the peerage), mainly on the Lancastrian side. The numbers often given are 42,000 for the Lancastrians and 36,000 for the Yorkists.
