The Society of the Cincinnati is a fraternal, hereditary society founded in 1783 to commemorate the American Revolutionary War that saw the creation of the United States. Membership is largely restricted to descendants of military officers who served in the Continental Army. The Society has thirteen constituent societies in the United States and one in France. It was founded to perpetuate "the remembrance of this vast event" (the achievement of American Independence), "to preserve inviolate those exalted rights and liberties of human nature," and "to render permanent the cordial affection subsisting among the officers" of the Continental Army who served in the Revolutionary War. Now in its third century, the Society promotes public interest in the Revolution through its library and museum collections, publications, and other activities. It is the oldest patriotic, hereditary society in America.

The Mahatma Gandhi Memorial is a public statue of Mahatma Gandhi, installed on a triangular island along Massachusetts Avenue, in front of the Embassy of India, Washington, D.C., in the United States. A gift from the Indian Council for Cultural Relations, it was dedicated on September 16, 2000 during a state visit of Indian Prime Minister Atal Bihari Vajpayee in the presence of US President Bill Clinton. Sparked to action in the wake of the 50th anniversary of Indian independence in 1947, the US Congress passed a bill in 1998 authorising the Government of India to establish a memorial to Gandhi on US federal land in the District of Columbia. The 8 ft 8 in (2.64 m) bronze statue depicts Mahatma Gandhi in ascetic garb, in reference to his 1930 march against the salt tax in India. It was designed by Gautam Pal, a sculptor from Kolkata. The statue is mounted on a 16 ton plinth of ruby granite from Ilkal, Karnataka, standing in a circular plaza of gray granite pavers. Behind it are three slabs of Karnataka red granite with inscriptions honoring Gandhi's memory, and in front of it is a seat also of red granite. The statue bears an inscription with Gandhi's answer to a journalist who asked for his message to the world: "My life is my message." The Mahatma Gandhi Memorial unveiled in Milwaukee in 2002 includes a similar statue by Gautam Pal, also mounted on a red granite plinth.
