The Aravalli mountain range, a natural barrier across four Indian states, historically resisted conquest by both the Delhi Sultanate and the Mughals. Despite significant military efforts and resources, these larger empires failed to subdue the region, which served as a stronghold for Rajput rulers like Maharana Pratap. The Aravallis' rugged terrain and strategic importance allowed smaller kingdoms to defy imperial powers for centuries, a historical context now relevant to modern discussions on protecting the ancient mountain system.
