Cantigny (käN-tē-nyē) is an autonomous country within the Kingdom of Engellex, located between the Gulf of Vesper and Implarian Ocean. Though physiographically a part of the continent of Himyar, Cantigny has been politically associated as its own continent for about a century. The largest island in Cantigny is also named Cantigny, and makes up most of the country's land area. Cantigny is, by area, the world's largest island.
Cantigny has been inhabited, though not continuously, by indigenous peoples since 2000 BC. There were significant aboriginal societies from AD 500 until sometime most likely in the 10th century. In the early 17th century contact between Europeans and Cantigny was established by Suionia, who established a settlement in 1595, though Engellex officially established rule over all of Cantigny early in the next century.
Cantigny became a colony, New Engellex, in 1623 when the explorer Charles Bennet established a permanent settlement at what is today called Port Fidelity. With the Woolwich Proclamation of 1913, Cantigny became a State and territory of Engellex in a relationship known as a Commonwealth.
In 1978 Engellex granted home rule to Cantigny, specifically in recognition of financial autonomy. The Engellexic royal government still heavily influences foreign affairs and defense policies in Cantigny, and Engellex maintains air, land, and sea fortresses in Cantigny on a permanent basis.
