Answer:
Human systems have made India the very diverse country that it is today.
Civilization in India was one of the first to emerge in world history. As centuries passed, new cultures developed in India, and each of these cultures left an influence to the ensuing states. Buddhism, Hinduism, Islam, the British Raj, are, to name a few, some of the cultural forces and human systems that have shaped what India is today.
Political systems are closely related to human systems simply because a political system is a human system. Each state that existed in the territory that is now India left a mark on successor states.
Nowadays, perhaps the most influential political system in India is still the British political system of the Raj. Without it, India would not have many of the political institutions that it has today, like a democracy, a Congress, or the mere fact of being an unified country .
