The square was originally called "Ismailia Square" ( ""), after the 19th-century ruler Khedive Ismail, who commissioned the new downtown district's 'Paris on the Nile' design. After the Egyptian Revolution of 1919, the square became widely known as Tahrir (Liberation) Square, but the square was not officially renamed until the Egyptian Revolution of 1952, which changed Egypt from a constitutional monarchy into a republic. The square was a focal point for the Egyptian Revolution of 2011.
