Every Modern-Day Country Colonized by Europeans

I would contest that Pondicherry and Goa should qualify France and Portugal under India respectively.

Very good quiz, although I think you're missing some stuff there, like Netherlands owning both Suriname and Guyana, because Guyana was mostly a British colony.

There are several errors. For example Guyana has been a british colony, not a dutch one. Many island nation which had been under british rule are here assigned only to other powers (St Lucia, St Vincent, St Kitts, Trinidad, Seychelles, Mauritius). Palau is missing, Micronesia has also been a german and spanish colony. For the US you should also add Russia (Alaska), Sweden (Delaware), Denmark (US Virgin Islands) and Germany (Northern Mariana Islands and Guam). Central Asia has been conquered by the Russian Empire, not by USSR, same for Caucasus countries. Some nations has been under portuguese rule for some time (Sri Lanka for example). Consistent parts of Gabon, R. of the Congo (and a bit fo Nigeria, Car and Chad) had been part of german Kamerun. Libya hasn't been colonized by the French. For China you should add Germany (Qingdao), for India Portugal, Denmark and France (Goa, Nicobares, Pondicherry) and for Ghana the Netherlands, Sweden and Denmark
