Democracy began in ancient Athens in 510 BC when soldiers chose leaders rather than having a monarchy. This early direct democracy had all citizens vote directly on laws. However, as populations grew, direct democracy became inefficient so representatives were elected in indirect democracy, as most democracies follow today. India adopted democracy due to its experience under colonial rule and to ensure unity among its diverse peoples, with features including federalism, parliamentary government, separation of powers, fundamental rights, and secularism.
