As a multi-ethnic and multi-religious country, India has had its share of sectarian violence and insurgencies in different parts of the country. Nonetheless, it has held itself together as a secular democracy barring a brief period from 1975 to 1977 during which the then Prime Minister Indira Gandhi declared a "state of emergency" with the suspension of civil rights. India has unresolved border disputes with China, which escalated into a brief war in 1962, and Pakistan which resulted in wars in 1947, 1965, and 1971. India was a founding member of the Non-Aligned Movement. In 1974, India conducted an underground nuclear test, making it an unofficial member of the "nuclear club", which was followed up with a series of five more tests in 1998. Significant economic reforms beginning in 1991, have transformed India into one of the fastest growing economies in the world.
