Architecture and Politics are two sides of the same coin. The architecture of an era gives us an in-depth insight into the political and cultural fabric of the society in those times. The desire of the early rulers to dominate and leave a lasting impression manifests itself in the architecture of those times. Starting from the division of northern India into 16 Mahajanapadas and the co-existence of the Chera, Chola and Pandya dynasty in the south, the period from 550 BC to 0 AD is one marked with tumult across the land of India, from mass religious conversions to the burning down of monasteries. Rivalries and alliances resulted in many architectural interventions, some of which, like the Kallanai Dam, or the Grand Anicut Canal, are still in use today in perfect condition. Our country's national emblem also belongs to this era, exemplifying the impact left for generations on politics and architecture.
