Hi, I saw your question regarding the kingdom Bavaria. Bavaria, Baden Würtemberg and other Kingdoms and free cities joined the german (2nd) Reich under supremacy of the kingdom Prussia. The king of Bavaria needed urgent money for the construction of his castle Neuschwanstein and accepted to be a part of Germany for a donation. Baden Würtemberg accepted under the condition of keeping their independent royal mail. The City of Hamburg joined under the condition to keep their free (toll-free) harbour. Todays second biggest harbour in Europe! In WW1 every kingdom kept their own units and led them by their princes, dukes, earls and every kingdom had their own decorations.
