Context: The use of the term Länder (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 Länder 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.
