Even if this will not influence in any way your political rights and does not have any practical uses anymore except maybe as part of your pride, the Constitution of the Free State of Bavaria (page 4) from 1946 still states in Article 6 that you will be a Bavarian Citizen thru
It also states that a law about this citizenship will work out the details. My online research could not find the content of this law.
Now here is my take on this:
In taking the oath to be an American citizen we gave up our German one but according to this Article 6 Paragraph 2 our pride to be “official” Bavarians, can never be taken away. As this does not say that you have to live within the state and as you are a born Bavarian your husband/wife will also become a citizen and going one step further so will your kids at their 18th birthday through “Legitimation” (however we will translate this term).
Granted, this constitution was written before the birth of the “Bundesrepublik Deutschland” (Federal Republic of Germany) of which Bavaria is now a part of, but it is still nice to know that we still belong.
So I will drink to that with a hearty Prosit!
