As the title suggests how would we get more nations like San Marino and Liechtenstein, small nations part of ethnic groups of larger nation-states but left out of consolidation because of geography or politics. San Marino left out of Italy not because they arent Italians but because of politics; Liechtenstein left out of Germany because of Austrian Empire/Austria-Hungary being between the principality and the rest of Germany; Luxembourg being left out of Germany because of politics, the personal union with Netherlands at the time of consolidation. So how do we get more little nations left out of the bigger nations? Doesn't have to be in Germany and Italy.
