Kongu Nadu & the 24 Nadus
Kongu Nadu is one of the historic regions of the Tamil country: the dry, red-soil interior of the west, watered by the Kaveri, Amaravati, Noyyal and Bhavani. For most of recorded history it was administered not as one block but as a mosaic of smaller units — the nadus.
Where and what it is
Kongu Nadu corresponds today to western Tamil Nadu — principally Coimbatore, Tiruppur, Erode, Salem, Namakkal, Karur, Dharmapuri, Krishnagiri, the Nilgiris and parts of Dindigul. It was one of the recognised divisions of ancient Tamilakam and, in the Sangam age, lay within the Chera sphere with its capital at Karuvur (Karur).Documented
The Sangam-age evidence
Two anchors matter. First, literature: the Chera-praising Patiṟṟuppattu, and references to the western country in Silappadikaram and other Sangam works. Second, the ground: Kodumanal, the excavated trade-and-industry town on the Noyyal (5th–1st century BCE) with its bead workshops, metallurgy and Tamil-Brahmi inscriptions, shows a literate, manufacturing, internationally-trading Kongu long before the medieval kingdoms.

The nadu system: 24 divisions
The characteristic administrative geography of Kongu is its division into 24 nadus — territorial units each covering a cluster of villages, remembered in community and inscriptional tradition. Names and boundaries vary between sources; the list below gives the commonly-cited nadus with the modern areas each covered. Tradition + inscriptional

Medieval to modern
After the Sangam Cheras, Kongu was ruled in turn by the Kongu Cheras and Western Gangas, the Cholas (under whom Karur flourished), the Hoysalas and Pandyas, then Vijayanagara and the Madurai Nayaks, and in the 18th century Mysore before the British reorganised it as Coimbatore district. Each layer left temples, tanks and inscriptions across the nadus. Documented
