Really just playing devil's advocate. I'll bow to conventional wisdom... and the Ethiopian tourism department.
I visited Ethiopia. They like to brag about being the only Africans never colonized. Though this seems like a hollow boast, as the Italians did control most of the country, albeit briefly. Most of the oldest buildings in Addis Ababa have an Italian signature. They still call the downtown area the Piazza. And they still have restaurants serving pizza everywhere. Doesn't seem very uncolonized.
No modern-day African country still has claims on it by European colonial powers. So... if an empire eventually relinquishing its claim on a land means that that land was never colonized, then no part of Africa was ever colonized by Europeans except maybe that one Spanish exclave that borders Morocco. Is there a time limit? Like the 5 second rule for food that falls on the floor? If you are colonized for 5 years it doesn't count?
Italy 'colonised' Ethiopia no more than Nazi Germany 'colonised' France.
If one country enters another country's territory uninvited, and they build only temporary military structures like barracks and fortifications before being forced out, this is an invasion.
If they do this but manage to largely defeat the defenders, and then build permanent structures like military bases or communications and transportation infrastructure, but they have no intent of actually sticking around permanently themselves and the presence is largely militaristic in nature, this is an occupation.
If they intend to stay and bring in people and families to live there, and they build permanent structures like churches, restaurants, administrative buildings
The Italian Empire intended to stay in Ethiopia. They built many of these things. If the war had gone differently, they would have still been there for another 40 years.
I spent over a year there so I find your incohorent ranting bizarre - you contradict yourself, for one thing. In the broadest sense, the main difference IS permanency. The war DID happen, they didn't have the resources to stick around, and were ousted within 5 years.
Why are you so upset?
Is it some arbitrary cut-off in time? Have there been no efforts to colonize territory in history that failed after fewer than 6 years? And if so, what's the next shortest one? I'm not sure how to look this up. I know of numerous failed attempts by European colonial empires to colonize North America. Most of those failed in less than a year, though.
So in short you could say there allready was settlement, but the jakarta of today was build/established by the dutch ( I wouldnt really use founded..)
As an Italian I blanked out completely, I definitely suggest revising the hint
