The Islands of Tuvalu consist of six atolls and reef islands. The smallest, Niulakita, was uninhabited until it was settled by people from Niutao in 1949.
Funafuti is the capital of Tuvalu. It is a true atoll that consists of 30 islands, or motu, as called by the Tuvaluans, surrounding a lagoon 20 kilometres north to south by 11 kilometres east to west.
The Constitution of Tuvalu states that it is "the supreme law of Tuvalu" and that "all other laws shall be interpreted and applied subject to this Constitution"; it sets out the Principles of the Bill of Rights and the Protection of the Fundamental Rights and Freedoms.
