Spanish Netherlands was the Habsburg Netherlands ruled by the Spanish branch of the Habsburgs from 1556 to 1714. They were a collection of States of the Holy Roman Empire in the Low Countries held in personal union by the Spanish Crown. This region comprised most of the modern states of Belgium and Luxembourg, as well as parts of northern France, the southern Netherlands, and western Germany with the capital being Brussels. The Army of Flanders was given the task of defending the territory.

Dutch is a West Germanic language, spoken by about 25 million people as a first language and 5 million as a second language and is the third most spoken Germanic language. In Europe, Dutch is the native language of most of the population of the Netherlands and Flanders. In South America, it is the native language of the majority of the population of Suriname, and spoken as a second language in the polyglot Caribbean island countries of Aruba, Curaçao and Sint Maarten. All these countries have recognised Dutch as one of their official languages, and are involved in one way or another in the Dutch Language Union. Dutch Caribbean municipalities have Dutch as one of the official languages too. Up to half a million native speakers reside in the United States, Canada and Australia combined, and historical linguistic minorities on the verge of extinction remain in parts of France and Germany.
