The Netherlands Antilles (Dutch: Nederlandse Antillen ), also referred to as the Dutch Antilles, was an autonomous Caribbean country within the Kingdom of the Netherlands, consisting of two groups of islands in the Lesser Antilles: Aruba, Curaçao and Bonaire (ABC Islands), in Leeward Antilles just off the Venezuelan coast; and Sint Eustatius, Saba and Sint Maarten (SSS Islands), in the Leeward Islands southeast of the Virgin Islands.
Aruba seceded in 1986 as a separate country within the Kingdom of the Netherlands, and the rest of the Netherlands Antilles was dissolved on 10 October 2010, resulting in two new countries, Curaçao and Sint Maarten .
They joined the Netherlands and Aruba as constituent countries forming the Kingdom of the Netherlands.
The three smallest islands - Bonaire, Sint Eustatius, and Saba - became special municipalities in the Netherlands administrative structure.
The name 'Netherlands Antilles' is still sometimes used to indicate the Caribbean islands which are part of the Kingdom of the Netherlands.
