Henry VII of England vs Ivan Asen I

Henry Tudor defeated and killed Richard III at Bosworth Field, ending the Wars of the Roses. This victory allowed Henry to claim the throne as Henry VII, founding the Tudor dynasty.

Henry VII married Elizabeth of York, uniting the Houses of Lancaster and York. This marriage symbolically ended the Wars of the Roses and strengthened the legitimacy of the Tudor claim to the throne.

Henry VII defeated the Yorkist pretender Lambert Simnel at the Battle of Stoke Field. This victory crushed a major rebellion and secured Henry's throne against early challenges to his rule.

Henry VII signed a treaty with Spain, arranging the marriage of his son Arthur to Catherine of Aragon. This alliance strengthened England's position in Europe and laid the groundwork for future diplomatic ties.

Henry VII executed Perkin Warbeck, a pretender who claimed to be Richard of Shrewsbury. Warbeck's capture and execution ended a major threat to Henry's reign and demonstrated his firm control over the kingdom.

Ivan Asen I, along with his brother Peter IV, led a successful uprising of Bulgarians and Vlachs against Byzantine rule. The rebellion began in Tarnovo and quickly spread, leading to the restoration of the Bulgarian state.

Ivan Asen I and his brother Peter IV established the Second Bulgarian Empire with its capital at Tarnovo. They were crowned co-emperors, marking the restoration of Bulgarian independence after nearly 170 years of Byzantine rule.

Ivan Asen I was assassinated by his cousin Ivanko, a boyar, during a period of internal conflict. His death temporarily destabilized the Second Bulgarian Empire, but his brother Peter IV continued to rule.
