India’s 66th Republic Day, which was celebrated Monday in New Delhi, was marked by several landmark events, including the first time that an American president was invited as chief guest at the annual event.

President Barack Obama and First Lady Michelle were present at the two-hour long parade, which typically showcases the country's military might as well as its diversity.

The year marked the first time ever that an all-woman contingent from the Army, Navy and Air Force marched in the Republic Day parade.
