2 NAGORNO-KARABAKH REPUBLIC
Nagorno-Karabakh is another post-Soviet state frozen in time. Known by its inhabitants as Artsakh, it has its own government, constitution, and military. Yet not a single other country recognizes it, not even Russia. Instead, the world considers it a part of Azerbaijan , the country it fought a brutal war of independence against in 1991–1994.
Part of this may be to do with geography. Nagorno-Karabakh is completely surrounded by Azerbaijan. Trapped up in the mountains and barely bigger than South Ossetia, it’s one of the most awkwardly positioned wannabe countries on Earth. A single corridor of occupied Azeri land connects it to Armenia—with whose people its citizens share ethnic roots—like a narrow umbilical cord. The likelihood of Armenia and Azerbaijan coming to an agreement over Nagorno-Karabakh’s status is unlikely. A shocking level of ethnic cleansing on both sides took place during the post-Soviet war, and fighting still claims
dozens of lives each year.

1 The Sovereign Military Order Of Malta
Unlike nearly every other hidden nation on this list, the Sovereign Military Order of Malta is recognized across the world. It has bilateral relations with 105 countries and diplomatic relations with another six (plus Palestine). It has a permanent observer status at the UN, and its passports are accepted in many of the world’s major nations. Yet it has literally no territory. Not only that, it doesn’t even lay claim to any.
This curious existence is down to the Order’s extremely long history . A group of Catholic knights that was founded in the 11th century, it once occupied and owned the island of Malta. Then, in 1798, Napoleon came to visit. Kicked off its homeland, the Order relocated to Italy, where Catholic nations continued to recognize it as a legitimate nation. Somehow, this state of affairs lasted the next 217 years. Today, the Order has control over just two buildings in Rome. It has no stated wish to reclaim the island of Malta, and its 13,500 members mainly involve themselves in humanitarian work. Yet to over half the world’s countries, including most of the EU and Canada, it remains a functioning state, accorded the same privileges as many nations.
