Prelude to the Battle of Bosworth Field

Since the end of the Hundred Years’ War with France, England had been in a state of civil warfare known as the Wars of the Roses.

The war was essentially between the rival factions of York and Lancaster both of which laid claim to the throne of England.

Richard III, a Yorkist monarch, ruled England in 1485. Although having staunch Yorkist support behind him, Richard’s reign was highly unpopular.

He was originally appointed as Lord Protector of his nephew, Edward V. During his Lordship, Edward V was declared illegitimate and Richard assumed the throne.

Preparations of the Battle of Bosworth Field

During most of Richard’s reign, Henry Tudor remained in Brittany where he effectively mustered the support of the Lancaster faction. In 1483, the unpopularity of Richard’s reign culminated in a number of uprisings, one of them most notably led by the Duke of Buckingham and spearheaded by Henry’s mother Lady Margaret.

Richard successfully put down the rebellions, executed Buckingham, and took away all titles of Lady Margaret. The conspirators who fled Richard’s wrath took refuge with Henry in Brittany.

By 1485, Henry Tudor had fled from Brittany to France and was aided by 2000 French mercenaries, he set sail for England.
