I'm sorry to have to correct you but in fact this (the Mauerfall) happened on the 9th of November. 3rd of October was chosen because there were two Nazi events that happened on 9th of November as well (1923 and 1939 respectively) which we (the Germans) obviously didn't want to give a holiday to

The real so called "Unification Day" (ger. Der Einigungs Tag) was 11.11.1990, but new government chooses different "official" date for it due to the historical very bad events that took place on that particular day in the past, which collides with this national, supposed to be happy, holiday. So officially is now the 3rd of October instead of the 11 November.
As for this "true democracy", well.. opinions are very different even now, as they were back then, few years after the event. 🤷‍♀️
