When were fundamental duties included in the consitution?

Fundamental duties were included in the constitution by the 42nd constitutional amendment in 1976. This included 11 amendments in section 4A and article 51A of the Indian constitution. Some of the fundamental duties included in the constitution are- to protect the unity, integrity and sovereignty of the state, to protect the nation and serve the nation on summon, to cherish the ideals of the freedom struggle, etc. The Duties cover a wide range of topics. However, violation of these Duties is not punishable by law.

Since the Indian Constitution guarantees citizens 6 Fundamental Rights, which are inalienable rights given to every citizen of the country, this also means that citizens have Fundamental Duties also. This is because Rights and Duties are two sides of the same coin. When we are given rights by the state, we also have duties towards the state.
