* Known as Richard the Lionheart for his bravery and military prowess during the Crusades.
* Led the Third Crusade (1189-1192) alongside other European rulers to re-conquer Jerusalem from the Ayyubid Sultan Saladin.
* Although he failed to recapture Jerusalem, he achieved significant victories against Saladin's forces and negotiated a truce that allowed Christian pilgrims access to the city.
* Defeated Saladin at the Battle of Arsuf in 1191, showing great martial leadership and tactical skill.
* Known for his chivalrous behaviour towards his opponents, such as releasing Saladin's brother Al-Adil after defeating him in battle.
Richard III of England:
* His major accomplishment was retaking control of England during the Wars of the Roses.
* After the Battle of Barnet in 1471, he defeated the Lancastrian forces loyal to the deposed King Henry VI and became King of England.
* Richard's victory marked the end of the prolonged conflict between the House of York and House of Lancaster and paved the way for the Tudor dynasty to take the throne.
Overall, while both Richard I and Richard III accomplished significant achievements, their contributions differ largely due to the different eras and contexts in which they ruled.
