Although Mita's answer is correct, I would like to add some interesting tidbits of info on this subject: It is nearly impossible for any country to retain the same name and borders as held during its nascency. Of course, this is due to the greed of all the warmongering and empire-building egos. The Netherlands is certainly no exception to this. To clarify, the Netherlands is actually made up of many distinct provinces; two of them being North and South Holland. Although, the two “Hollands” being relatively small in terms of land area contain nearly half of the population of the Netherlands. More importantly, North and South Holland are located on the North Sea thereby controlling most of the shipping making them the richest provinces; and also being home to the capital and seat of government has its own influence too. Hence, he who holds the purse can pretty much call all the shots. Furthermore, the word Dutch in itself (Dutch, meaning inferior) was bestowed upon them by the lovely English imperialists. And during the French control of the Netherlands many of the smaller provinces were exploited as colonies (ironically, not too dissimilar to what the Dutch East Indies company did to parts of Asia) thereby, creating great resentment towards “Holland.” Some of that which still remains today. Adding insult to injury would be to incorrectly assume a Dutch person from any part of the Netherlands is from Holland. Oh and John Cruyff and Ruud Gullit don’t count because they’re actually from Holland! :P

People usually call Netherlands with Holland but actually Holland is a name of region in the western part of Netherlands. That's all I know ^^
