For various reasons, many cities and countries around the world have changed their name over the years. Provide the name under which these places are known today.
In cases where a place was split or consolidated, the modern city or country containing the largest proportion of the old is used.
Nice quiz, but some of your former and modern names do not tie up. The Sultanate of Zanzibar was a small group of islands off the African coast, which became a colony. That then merged with the much larger colony of Tanganyika to form Tanzania. There is no way that someone would see the two to be the same thing, it is a bit like saying the "Rhode Island" is the former name of the USA.
