Why did Prince Aloys Gonzaga Maria Adolf 1869-1955 renounced his succession rights in favor of his son 1923?

he was the father Prince Franz Josef II and he was married to Archduchess Elisabeth Amalia of Austria

I can't find any concrete answer to your question. However, Prince Aloys was 54 years old when he renounced his rights to the throne in favor of his son. Prince Franz Josef II started his reign 15 years later which would've put Aloys at close to 70 years of age. We may never know.

I think that something can be here, but my French is almost none- it's something to do about him as Emperor Franz Josef I nephew and succession changing:

Né le 16 août 1906, le prince François Joseph est le filleul de son grand-oncle l'empereur François Joseph Ier d'Autriche, dont il reçoit les prénoms.
Troisième dans l'ordre de succession au trône, son père renonce à ses droits en sa faveur le 26 février 1923.
François Joseph devient ensuite deuxième dans l'ordre de succession le 11 février 1929 à la mort du prince souverain Jean II de Liechtenstein. Il devient l'héritier présomptif du trône le 26 août 1929, à la mort de son oncle le prince François de Liechtenstein (1868-1929).
Il succède le 25 juillet 1938 à son cousin et grand-oncle le prince souverain François Ier de Liechtenstein, qui n'a pas eu d'enfant. Le prince François-Joseph II et sa femme seront les premiers souverains de Liechtenstein à vivre dans la principauté au château de Vaduz. Diplomate et avisé, François-Joseph II saura faire du Liechtenstein un havre de paix et de prospérité, notamment grâce à l'instauration de conditions fiscales avantageuses pour les entreprises.

Anyone can translate it?

Just what we already know. Mainly that Prince Aloys renounced in favor of his son and that Franz Josef II (with Princess Gina)as ruling prince was the first sovereign to live in the principality at Vaduz Castle.

Nothing as to why Prince Aloys renounced his rights.
