The Fundamental Duties were added by the 42nd Constitutional Amendment Act of 1976 and one more duty was added by 86th Constitutional Amendment,2002. The original Constitution did not provide for Fundamental Duties. Part IV-A of the Constitution provides for these duties. These duties serve as a reminder to the citizens while enjoying their rights that they have some duties to perform towards the country, society, and fellow citizens. The Concept of Fundamental Duties was taken from the Soviet Constitution(USSR) which is now called Russia.
