Dutch people
Dutch people (Dutch: ) or the Dutch are a Germanic ethnic group native to the Netherlands. They share a common culture and speak the Dutch language. Dutch people and their descendants are found in migrant communities worldwide, notably in Aruba, Suriname, Guyana, Curaçao, Argentina, Brazil, Canada, Australia, South Africa, New Zealand, and the United States. The Low Countries were situated around the border of France and the Holy Roman Empire, forming a part of their respective peripheries, and the various territories of which they consisted had become virtually autonomous by the 13th century. Under the Habsburgs, the Netherlands were organised into a single administrative unit, and in the 16th and 17th centuries the Northern Netherlands gained independence from Spain as the Dutch Republic. The high degree of urbanization characteristic of Dutch society was attained at a relatively early date. During the Republic the first series of large-scale Dutch migrations outside of Europe took place.
Batavianization
The term "Batavianization", derives its name from the Batavi, a Germanic tribe living in the Netherlands, and long regarded as the mythical ancestors of the Dutch people. The term "Dutchification" is mostly used in English publications by Dutch authors, less so by native English-speakers. This likely has to do with the fact that "Dutch" isn't a Latin-derived term and hence sounds somewhat childish to some ears in combination with the (Latinate) suffix "-fication". As for "Belgianization", "Belgae" was the standard term in Latin to refer to the Dutch (compare the Leo Belgicus, United Belgian States and Belgic Confession for example) in the Late Middle Ages. After the establishment of Belgium, its use generally shifted to mean Belgicism.
