Towns are founded to succeed. Some do and grow out of all recognition. Some fail and disappear into the ground. Some few fall into a vegetative state and keep going without growing. They are the ones to visit like Palmanova in Italy. Like a time capsule, the town remains almost unchanged since the time of Napoleon. It was founded by the Republic of Venice as the ideal Renaissance town.
The Principality of Liechtenstein is sandwiched between Austria and Switzerland. It is a hereditary principality with political powers shared equally between the elected parliament and the prince. Nobody knows what happens if ever they should agree to disagree because there is no proviso for a resolution process. The prince is also head of state.
There are Princes and Princesses, and then there are Princes and Princesses. Some are Royal or more, some are not. The problem lies in geography. Depending on where the title came from, the title of Prince does not mean the same thing. The puzzle can be solved given some knowledge of geography and history, and quite some of the muddle derived from translating foreign titles into English.
