RRB Group D GK GS Union and Its Territories FAQs

Why is India called a 'Union of States' rather than a 'Federation'?

As per Article 1, India is a "Union" because states do not have the right to secede from the Union, and it is not the result of a voluntary agreement between states.

Which is the newest state of India?

Telangana is the newest state, formed on June 2, 2014, following the bifurcation of Andhra Pradesh.

Can the Parliament change the name of a state without its consent?

Under Article 3, the Parliament has the power to change the name or boundary of a state. While the President refers the bill to the state legislature for views, the Parliament is not bound by those views.
