His parents and their children then moved to Munich, with support from his mother's relatives from the Thurn und Taxis dynasty.

On 13 February 1961, he received his PhD for a thesis on his great-great-grandfather, King John of Saxony, and his reform of Saxon commercial law.

("Study group for Saxon history and culture") was founded by Albert together with his parents, his elder brother Maria Emanuel, some other Saxon nobles, the Chapter of the Military Order of St. Henry, the chapter of the association of people from Dresden, and the association of Heimatvertriebene in the history department of the University of Munich.

[5] [6] The first designated dynastic heir of Maria Emanuel was his and Albert's nephew Prince Johannes of Saxe-Coburg and Gotha, only son of their youngest sister Princess Mathilde of Saxony by her marriage to Prince Johannes Heinrich of Saxe-Coburg and Gotha, dynast of a ducal branch of the House of Wettin senior patrilineally to the royal branch.

[6] After the early death of Prince Johannes, the heirless Maria Emanuel then considered as potential heir another nephew, Alexander Afif, the eldest son of Princess Anna of Saxony and her husband Roberto Afif, despite the Afif-Saxony marriage being contrary to the traditional laws of the House of Saxony which required equal marriages for descendants to inherit dynastic rights.

[12] Until his death, however, the Margrave, as head of the former dynasty, continued to regard his nephew and adopted son, Prince Alexander, as the contractual heir entitled to succeed.

[citation needed] Immediately following the death of Maria Emanuel in July 2012, Prince Albert assumed the position of head of the Royal House of Saxony.

[citation needed] Prior to the requiem for Margrave Maria Emanuel, Rüdiger, who had sought to be recognised by his cousin as a dynastic member of the House of Saxony but was refused, conducted a demonstration outside the cathedral with Saxon royalists in protest against the late Margrave Maria Emanuel's decision to appoint Alexander as heir.
