Article: Thuringia became a landgraviate in 1130 AD. After the extinction of the reigning Ludowingian line of counts and landgraves in 1247 and the War of the Thuringian Succession (1247–1264), the western half became independent under the name of "Hesse", never to become a part of Thuringia again. Most of the remaining Thuringia came under the rule of the Wettin dynasty of the nearby Margraviate of Meissen, the nucleus of the later Electorate and Kingdom of Saxony. With the division of the house of Wettin in 1485, Thuringia went to the senior Ernestine branch of the family, which subsequently subdivided the area into a number of smaller states, according to the Saxon tradition of dividing inheritance amongst male heirs. These were the "Saxon duchies", consisting, among others, of the states of Saxe-Weimar, Saxe-Eisenach, Saxe-Jena, Saxe-Meiningen, Saxe-Altenburg, Saxe-Coburg, and Saxe-Gotha; Thuringia became merely a geographical concept.

Now answer this question: Who did the Saxon Duchies consist of?
the states of Saxe-Weimar, Saxe-Eisenach, Saxe-Jena, Saxe-Meiningen, Saxe-Altenburg, Saxe-Coburg, and Saxe-Gotha
