This article uses an in-universe perspective.
This article deals with the information known of the small country in the west of Europe, the Netherlands. Before World War Z, it was a well developed nation, known for its climate of tolerance, its stance on drugs and many brands of high quality beer. Little is known of it since the war ended.
World War Z
Max Brooks, author of World War Z, gives a historical view of the world during the zombie wars, based on research prior to the actual war. This research ended up in his survival manual, The Zombie Survival Guide. Correctly placing the blame on the virus called Solanum, Brooks identified a physician in the early 20th century that first named it such. His name was Jan Vanderhaven (or, more likely, Jan van der Haven, as per Dutch naming conventions), and he did thorough research into Solanum that eventually was published. Max Brooks obtained a manuscript of this year-long study and subsequently included it in his manual.
The only recorded outbreak of Solanum zombies in the Netherlands prior to WWZ was in roughly 700 AD. A painting was discovered in the vaults of the Dutch Rijksmuseum in Amsterdam. It depicted a band of knights battling the living dead in full armor. All typical signs of Solanum was present in the creatures, namely mottled skin, inability to feel pain and a craving for human flesh. While it has been dated using the materials and the paints utilized to make this painting, its creator is unknown.
When the Solanum outbreaks hit, it was only a matter of time before the zombies reached this small nation. The historian Max Brooks did not include many details on the country in his history book, but did find someone who had a scrap of information on one certain subject. This person was David Allen Forbes, a Brit who survived in Windsor Castle. After the war, he traveled around the globe to see castles where people had fought against the zombies. According to him, the Dutch castle of Muiderslot fell in part because of an outbreak of pneumonia. Coupled with isolation, malnutrition, a lack of medication, and of course the ever-present threat of the zombies, and it was no wonder that the inhabitants were all dead before the end of the siege.
