Indira Priyadarshini Gandhi (Hindi: इंदिरा प्रियदर्शिनी गांधी Indirā Priyadarśinī Gāndhī  listen (help·info), née Nehru; 19 November 1917 – 31 October 1984) was an Indian politician who served as the third Prime Minister of India for three consecutive terms (1966–77) and a fourth term (1980–84). Gandhi was the second female head of government in the world after Sirimavo Bandaranaike of Sri Lanka, and she remains as the world's second longest serving female Prime Minister as of 2012. She was the first woman to become prime minister in India.

Gandhi was the only child of Jawaharlal Nehru, the first prime minister of independent India. She adhered to the quasi-socialist policies of industrial development that had been begun by her father. Gandhi established closer relations with the Soviet Union, depending on that nation for support in India’s long-standing conflict with Pakistan. She was also the only Indian Prime Minister to have declared a state of emergency in order to 'rule by decree' and the only Indian Prime Minister to have been imprisoned after holding that office. She was assassinated by her Sikh bodyguards in retaliation for ordering Operation Blue Star.

Indian Americans are Americans whose ancestral roots lie in India. The U.S. Census Bureau uses the term Asian Indian to avoid confusion with the indigenous peoples of the Americas commonly referred to as American Indians.

In North America, the term Indian has an ambiguous meaning. In the western hemisphere, historically and currently, Indian has been commonly used to refer to the indigenous peoples of the Americas. Qualifying terms such as American Indian and East Indian were and are commonly used to avoid ambiguity.

While East Indian remains in use, South Asian is often chosen instead. The U.S. government coined Native American to refer to the indigenous peoples of the United States, but American Indian remains popular among the indigenous and general populations.

People of Indian origin often prefer the term Desi to refer to the diasporic subculture of South Asians. Indian Americans are categorized as Asian Indian (and more broadly, Asian American) by the United States Census Bureau.

It was after the Luce–Celler Act of 1946, that Indian Americans were restored naturalization rights in the United States.
