Unlike other European nations, the Dutch chose not to follow a policy of language expansion amongst the indigenous peoples of their colonies. In the last quarter of the 19th century, however, a local elite gained proficiency in Dutch so as to meet the needs of expanding bureaucracy and business. Nevertheless, the Dutch government remained reluctant to teach Dutch on a large scale for fear of destabilising the colony. Dutch, the language of power, was supposed to remain in the hands of the leading elite.
Towards the end of what century did it become important for more people in Dutch colonies to speak Dutch?
