Here's why he is referred to as such:
* Military Prowess: Ahmad Shah was a brilliant military strategist and leader who was known for his courage and ferocity in battle. He successfully unified the Pashtun tribes under his banner and led them to numerous victories against the Persian, Mughal, and Sikh empires.
* National Symbol: His achievements and the legacy of the Durrani Empire made him a symbol of Pashtun strength and power. The title "Lion of Pashtun" signifies his role in uniting the Pashtun people and establishing their dominance in the region.
While Ahmad Shah Durrani is the most prominent figure associated with the title "Lion of Pashtun," it's worth noting that other individuals have been called this throughout history.
However, Ahmad Shah's legacy and the significance of his reign are arguably the most compelling reasons why he remains the most widely recognized as the "Lion of Pashtun."
