Amount of modern countries of the Dutch Empire

This is a chart about the amount of modern countries of the Dutch Empire trough the years. The total amount of countries the Dutch Empire had all time was 66 countries. Oceania:the Dutch were the first to invade Australia, New Zealand and Tonga, Fiji and other Island in Oceania. They discovered it and visited it, but they did not colonize it. So I don't count them in this chart. In Australia and New Zealand you also see many place names that were invented by the Dutch.
