Yes Turkey is successor of Ottoman heritage and It can be accepted as It's extend but It isn't the just same country with it.
I also missed some obvious ones: Russia and Bolivia.
Japan: Occupied by the allies (USA) after World War 2.
Haiti:Occupied by USA 1915-1934
Greece: Occupied by Germany during World War 2
I am not sure how to understand Russia. That it was not conquered ? Not conquered entirely, or foregin troops were not on Russian soil until they called the country Russia? Russian teritory was under Polish control in the 16th century.
What about the Russian Soviet Federative Socialist Republic (as part of the USSR). Part of it was under german control during WWII (Leningrad and Stlingrad was under siege, the german troops reached the borders of Moscow so weel within russian borders).
And the last one is Argentina. I believe that the war over the Falkland Islands with the UK should eliminate Argentina from this list.
-Manchuria is an integral part of China and has been for a long time. It was the central part of the Jin Dynasty in the 12th Century and part of the 13th Century Yuan Dynasty as well. The Jin may not have been Chinese originally but they were made sufficiently Chinese after expanding their empire deep into China, and these people were the precursors of the Qing. The Yuans were led by Mongols but also became Sinicized over time. Manchuria was conquered but then retaken by the Han Chinese Ming Dynasty for nearly 300 years. The Qing Dynasty was far from the first time that Manchuria had been a part of China. It has been part of Chinese history for nearly 1000 years prior.
-Manchus are currently the 4th largest ethnic group in China. There are a small number living in Russia but the overwhelming majority are Chinese.
1291 is the foundation, 1815 it's restored and federal state is created in 1848.
If the date is 1291, you can't put it on this quizz (ex : Helvetican Republic after Napoleon's changes in 1803.
If the date is 1848, ok but the date have to be upgraded.
Those informations are confirmed by Wikipedia. ;)
All of those countries were protectorates of the UK even after 1850.
What is the criteria?
Portugal was not controlled by French Empire during Napoleon invasions. French invaded Portugal and there were many battles, but they never had political control. In fact officially they never took control of the main cities Lisbon or Porto, despite of the atempts. The French killed many people, sacked lots of precious objects, food, etc, but they NEVER had control of the territory.
Likewise the Swedish conquered Moscow in 1610 but you are not counting it and that;s correct because Russia did not lose sovereignty, even though they had another country invading the territory. And like that it happened to other countries in this list...countries that were invaded, there were battles without losing sovereignty. Last time Portugal was officially ruled by other country was in 1640, at that time Spain ruled Portugal.
(referring to Europeans here mostly)
I mean, the Latin American nations emancipation from Europe (basically: Spain, Portugal and France) came on the heels of the US independence, the French Revolution and the Napoleonic Wars. Australia was still a British Dominion during WWI, almost a century later.
Anyway, good quiz!
Also I'm not really sold on the Manchu justification for not including China - since 1850 Manchuria has continually been a part of China (and for centuries prior).* The Manchus weren't ethnically Han Chinese, but I'm not sure this is a quiz about the ethnic make up of the government and I think you're getting into pretty weird territory when you start saying a nation has been "conquered" because its leaders come from an ethnic minority.
*As far as I'm aware, Manchukuo never received formal international recognition
