The famous Scottish leader known for his role against English rule in the early medieval period is William Wallace. He emerged as a central figure during the First War of Scottish Independence. Wallace's leadership during pivotal battles, including the Battle of Stirling Bridge, made him a symbol of Scottish resistance against English domination. His quest for freedom and determination were immortalized in narratives like the film "Braveheart." Sadly, he was ultimately captured by the English and executed, but his legacy continues to inspire Scottish nationalism and pride.
