The use of the term Lander (Lands) dates back to the Weimar Constitution of 1919. Before this time, the constituent states of the German Empire were called Staaten (States). Today, it is very common to use the term Bundesland (Federal Land). However, this term is not used officially, neither by the constitution of 1919 nor by the Basic Law (Constitution) of 1949. Three Lander call themselves Freistaaten (Free States, which is the old-fashioned German expression for Republic), Bavaria (since 1919), Saxony (originally since 1919 and again since 1990), and Thuringia (since 1994). There is little continuity between the current states and their predecessors of the Weimar Republic with the exception of the three free states, and the two city-states of Hamburg and Bremen.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What were the states of Saxony called before 1919?
Ah, so.. unanswerable

The Marshall Islands also lays claim to Wake Island. While Wake has been administered by the United States since 1899, the Marshallese government refers to it by the name Enen-kio.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): In what year did the US take control of Wake Island?
Ah, so.. 1899

Britain's remaining colonies in Africa, except for self-governing Southern Rhodesia, were all granted independence by 1968. British withdrawal from the southern and eastern parts of Africa was not a peaceful process. Kenyan independence was preceded by the eight-year Mau Mau Uprising. In Rhodesia, the 1965 Unilateral Declaration of Independence by the white minority resulted in a civil war that lasted until the Lancaster House Agreement of 1979, which set the terms for recognised independence in 1980, as the new nation of Zimbabwe.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When was the second-to-last British colony in Africa granted independence?
Ah, so..
1968
