Michael, is the current head of the Grand Ducal House of Saxe-Weimar-Eisenach, as well as the most senior agnate of the entire House of Wettin.
Prince Michael was born in Bamberg, Bavaria, the only son of Hereditary Grand Duke Charles Augustus of Saxe-Weimar-Eisenach and Baroness Elisabeth of Wangenheim-Winterstein (1912–2010).
When his father died in 1988, Michael succeeded as Head of the House of Saxe-Weimar-Eisenach. In 1991 he inherited the leadership in the House of Saxe-Altenburg, as that line went extinct and since 2012 he regards the Albertine royal Saxon line to also be extinct. In 2004 he withdrew his claim for restitution of numerous properties, archives (partly including those of Schiller and Goethe) as well as priceless artwork in a settlement with the Free State of Thuringia and acquired some forest estates in exchange.
Michael is in the line of succession to the British throne, being a great5-grandson of Princess Augusta, eldest sister of King George III.
