The Chauhans (also known as Chahamanas) were a prominent Rajput dynasty in early medieval India.
Their place of origin is traditionally believed to be Sapadalaksha, a historical region.
Sapadalaksha refers to a region comprising parts of present-day Rajasthan, particularly around Sambhar Lake.
It was a territorial division mentioned in early inscriptions and texts.
It later included areas like Ajmer, which became an important Chauhan stronghold.
