Before 1945 there was no Indonesia, but rather a collection of islands spread across the Equator that the Dutch made into the Netherlands East Indies. In 1898 a new queen, Wilhelmina, ascended the throne of the Kingdom of the Netherlands. Wilhelmina's tropical empire, known simply as the Indies, numbered more than 28 million subjects on the prime island of Java, and some 7 million others on what were referred to as the Outer Islands, although not all of these as yet were under Dutch rule. Although she ruled for the rest of the colonial period, Wilhelmina never visited her colony. She never experienced the sudden monsoonal downpours, the green landscapes dominated by volcanoes, or the spicy heat, but every year her birthday was celebrated there, with night markets and festive arches.

What was it like for the Dutch, ruling that vast archipelago of Indonesia? The Dutch made up a special, upper social class of the Indies – soldiers, administrators, managers, teachers, pioneers. They lived linked to, and yet separate from, their native subjects. From 1900 to 1942 these colonial rulers worked to make the islands into a single, prosperous colony, and for that they expected gratitude.
