Montenegro

Montenegro is the smallest of the Balkan nations and it appears in all European scenarios. It has a (★) nation with a hard difficulty.

A.D 1865
Montenegro is very small being squished between the Austrian Empire, Bulgaria, and Greece which only one of those countries are your enemies. Its allies are France, Italy, the Austrian Empire, the Russian Empire, Greece, Portugal, and Denmark Its general is Nicholas I and that's it. Montenegro is one of the hardest nations in this game as it lacks money and resources and the Ottoman Empire poses a huge threat and Romania and Bulgaria can also pose a mild threat

A.D 1914
Montenegro retains everything from 1865 but has a different shape and also loses its borders only with Austria-Hungary, Serbia and Greece. Its allies are the United Kingdom, France, the Russian Empire, Italy, Portugal, Serbia, Romania, and Greece. Its now even more fragile due to Austria creeping in from the north and in your coast. Thus, and the lack of money makes it worse.

A.D 1917
Montenegro still has the same general but is slightly more richer and its allies are more centralised so its more easier than 1914. Its new allies are the United States, Brazil, Peru, Morocco, and Libya. Other than that, there's nothing much to say about Montenegro in this era
