The Country that made your Country Exist (Patreon)

So, I'm trying to develop a theory of culture and one of the main tenets of it is that the nation is formed to fight off an external threat, almost always a foreign invader, or was created by an invader to unite the subdued peoples. This is a map of what external threat caused ___ country to exist. I'm looking at the modern nations rather than the ones they were built off, such as for Germany I could go to the Holy Roman Empire and say the Romans or Magyars created their identity but I went with modern Germany, who's nationalism was formed by the Napoleonic invasions. 

Here are some of the stranger ones that need explaining.

1)New Zealand and Australia formed by Turkey-The Entente invasion of Turkey at Gallipoli was what forced those nations to differentiate their identities from Britain and realize that they had more in common with each-other than with their cousins at home.

2)Algeria and Tunisia formed by Spain-These nations were formed in their modern form by the Barbary city states along the coast being forced to fight off Spanish conquest in the 16th century. They only barely prevented the Spaniards from taking over the Maghreb. 

3)Shit I didn't feel like labeling in South America. Paraguay was originally a province of Argentina and broke off with its own war of Independence. Similarly, Uruguay fought a war of Independence from Brazil. Ecuador and Venezuela broke off from Grand Colombia in the early 19th century. Similarly, Central America broke off from Mexico in the early 19th century.

4)Oman, Angola and Mozambique were formed to fight off Portugal.

5)Egypt and China were formed as nations predominantly due to the need to manage the irrigation canals necessary for agriculture in both regions and not due to external threats.
