Lagoons are commonly divided into coastal lagoons and atoll lagoons. They have also been identified as occurring on mixed-sand and gravel coastlines. There is an overlap between bodies of water classified as coastal lagoons and bodies of water classified as estuaries. Lagoons are common coastal features around many parts of the world. - India, officially the Republic of India ("Bhrat Gaarjya"), is a country in South Asia. It is the seventh-largest country by area, the second-most populous country (with over 1.2 billion people), and the most populous democracy in the world.

The atoll is administered by the United Kingdom through the British Indian Ocean Territory (BIOT). - The Indian Ocean is the third largest of the world's oceanic divisions, covering (approximately 20% of the water on the Earth's surface). It is bounded by Asia on the north, on the west by Africa, on the east by Australia, and on the south by the Southern Ocean or, depending on definition, by Antarctica. It is named after the country of India. The Indian Ocean is known as "Ratnkara", ""the mine of gems"" in ancient Sanskrit literature, and as "Hind Mahsgar", ""the great Indian sea"", in Hindi. - An island or isle is any piece of sub-continental land that is surrounded by water. Very small islands such as emergent land features on atolls can be called islets, skerries, cays or keys. An island in a river or a lake island may be called an eyot or ait, and a small island off the coast may be called a holm. A grouping of geographically or geologically related islands is called an archipelago, e.g. the Philippines. - The British Indian Ocean Territory (BIOT) is an overseas territory of the United Kingdom situated in the Indian Ocean halfway between Tanzania and Indonesia. The territory comprises the seven atolls of the Chagos Archipelago with over 1,000 individual islandsmany very smallamounting to a total land area of . - The Chagos Archipelago (or ) or Chagos Islands (formerly the Bassas de Chagas, and later the Oil Islands) is a group of seven atolls comprising more than 60 individual tropical islands in the Indian Ocean about south of the Maldives archipelago. This chain of islands is the southernmost archipelago of the Chagos-Laccadive Ridge, a long submarine mountain range in the Indian Ocean. - An atoll (, , , or ), sometimes called a coral atoll, is a ring-shaped coral reef including a coral rim that encircles a lagoon partially or completely.

Other nearby island countries and territories include Comoros, Mayotte (region of France), Madagascar, Reunion (region of France) and Mauritius to the south. With a population of roughly 92,000, it has the smallest population of any sovereign African country; however, it does have a larger population than the British overseas territory Saint Helena, Ascension and Tristan da Cunha. - The Napoleonic Wars (1803-1815) were a series of major conflicts pitting the French Empire and its allies, led by Napoleon I, against a fluctuating array of European powers formed into various coalitions, primarily led and financed by the United Kingdom. The wars resulted from the unresolved disputes associated with the French Revolution and the Revolutionary Wars, which had raged on for years before concluding with the Treaty of Amiens in 1802. The resumption of hostilities the following year paved the way for more than a decade of constant warfare often categorized into five conflicts: the War of the Third Coalition (1805), the War of the Fourth Coalition (1806-7), the War of the Fifth Coalition (1809), the War of the Sixth Coalition (1813), and the War of the Seventh Coalition (1815). The Napoleonic Wars had profound consequences for global and European history, leading to the spread of nationalism and liberalism, the rise of the British Empire as the world's premier power, the independence movements in Latin America and the collapse of the Spanish Empire, the fundamental reorganization of German and Italian territories into larger states, and the establishment of radically new methods in warfare. - The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a sovereign country in western Europe. Lying off the north-western coast of the European mainland, it includes the island of Great Britain (the name of which is also loosely applied to the whole country), the north-eastern part of the island of Ireland, and many smaller islands. Northern Ireland is the only part of the UK that shares a land border with another sovereign statethe Republic of Ireland. Apart from this land border, the UK is surrounded by the Atlantic Ocean, with the North Sea to its east, the English Channel to its south and the Celtic Sea to its south-south-west, giving it the 12th-longest coastline in the world. The Irish Sea lies between Great Britain and Ireland. With an area of , the UK is the 78th-largest sovereign state in the world and the 11th-largest in Europe. It is also the 21st-most populous country, with an estimated 65.1 million inhabitants. Together, this makes it the fourth most densely populated country in the European Union. - Diego Garcia is an atoll just south of the equator in the central Indian Ocean, and the largest of 60 small islands comprising the Chagos Archipelago. It was settled by the French in the 1790s and was transferred to British rule after the Napoleonic Wars. It was one of the "Dependencies" of the British Colony of Mauritius until it was detached for inclusion in the newly created British Indian Ocean Territory (BIOT) in 1965. Between 1968 and 1973, the population was forcibly removed by the United Kingdom through intimidation of locals and denying the return of any who left the island. Many were deported to Mauritius and Seychelles, following which the United States built a large naval and military base on Diego Garcia, which has been in continuous operation ever since. , Diego Garcia is the only inhabited island of the BIOT; the population is composed of military personnel and supporting contractors. - The Maldives (, or ), officially the Republic of Maldives (""), is a South Asian island country, located in the Indian Ocean.
