The term was popularized in the late 1970s, after Prime Minister Indira Gandhi declared a state of emergency across the country that lasted for 21 months.

At the time, Ms. Gandhi faced mounting challenges. Economic distress had led to widespread riots and protests, while a state high court had convicted her of election fraud.

Instead of resigning, she installed a curfew and censored the press. She also jailed hundreds of political opponents — many from early predecessors of the B.J.P. — without trial, deriding them as anti-nationals.

With the resurgence of the term today, the question is whether it “tells us more about the people accused” or the accusers, writes the journalist and author Raghu Karnad. — Alisha Haridasani Gupta
