There are 11 fundamental duties in India. Initially, 10 fundamental duties were incorporated into the Indian Constitution through the 42nd Constitutional Amendment Act in 1976. Subsequently, the 86th Constitutional Amendment Act of 2002 added the 11th duty, making a total of 11 fundamental duties listed under Article 51A of the Indian Constitution. These duties serve as moral obligations for Indian citizens and aim to promote patriotism and national unity, but they are non-justiciable, meaning they are not legally enforceable by the courts.
