English is the current lingua franca of international business, science, technology and aviation. It has replaced French as the lingua franca of diplomacy since World War II. The rise of English in diplomacy began in 1919, in the aftermath of World War I, when the Treaty of Versailles was written in English as well as in French, the dominant language used in diplomacy at that time. The widespread use of English was further advanced by the prominent international role played by English-speaking nations (i.e., the United States and the Commonwealth of Nations) in the aftermath of World War II, particularly in the establishment and organization of the United Nations and the development of the Internet. English is one of the six official languages of the UN and, along with French, one of the two working languages; the other official languages being Arabic, Chinese, Russian and Spanish
