The last Czar of Russia was Nicolas II.
It really depends on the perspective you put it into. If you were a African that was taken from your home land, and forced to board a ship with hundreds of other Africans were you could barely stand, wouldn't you say the trade of slaves? But this also brought economic wealth to the Americas and it also help support the trade of sugar. This can be debatable though.

At first the United States tried to stay neutral, and by 1917, Woodrow Wilson created a policy about neutrality in the War and he announced that the U.S has to be neutral.
One reason the U.S decided to enter, however, was because of the horrible doings of the Germans in Belgium, and the sinking of the Lusitania (a German submarine sunk the Lusitania filled with many English and American citizens) which is most popularly viewed as the reason for the United States getting involved.
The reasons that the Americans fought along with Colombians, Ethiopians, and Puerto Ricans, were mostly geostartegic, economic, and territorial.
They fought along with the Colombians because Colombia has an excellent geostrategic position in the continent that is not very fond of the US. So by having an ally in Colombia they were able to have much better control and to be in a much better position on the affairs in South America.
Ethiopia was a zone of interest because it is crucial as a military base that will be close to the Middle East, so having an ally in them was allowing them to build their military facilities.
Puerto Rico was a territorial zone of interest, and the US wanted to keep it under its own governing because an independent country of Puerto Rico might have gone in any direction really, and even become an ally with some of the American arch enemies, and thus becoming the ''second Cuba''.
