The United Provinces of the Netherlands, officially the Republic of the Seven United Netherlands, and commonly referred to in historiography as the Dutch Republic, was a confederation that existed from 1579 until the Batavian Revolution in 1795. It was a predecessor state of the present-day Netherlands, and the first independent Dutch state. The republic was established after seven Dutch provinces in the Spanish Netherlands revolted against Spanish rule, forming a mutual alliance against Spain in 1579 and declaring their independence in 1581. It comprised Groningen, Frisia, Overijssel, Guelders, Utrecht, Holland, and Zeeland.

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.
