Tamil Nadu has a long historical timeline that includes ancient civilizations like the Sangam period. The region saw the rise of powerful dynasties like the Cholas, Cheras, Pandyas, and Pallavas. These kingdoms contributed to temple architecture, literature, and maritime trade that shaped the region’s identity.
The Chola Empire, in particular, left a lasting legacy through its grand temples, administrative systems, and naval expeditions. Later, the region came under the rule of the Vijayanagara Empire, the Nayaks, and the British.
