A European microstate or European ministate is a very small sovereign state in Europe. In modern usage, it typically refers to the six smallest states in Europe by area: Andorra, Liechtenstein, Malta, Monaco, San Marino, and Vatican City (the Holy See).[1] Andorra, Liechtenstein, Monaco and Vatican City are monarchies (Vatican City is an elective monarchy ruled by the Pope). These states trace their status back to the first millennium or the early second millennium except for Liechtenstein, created in the 17th century.
Microstates are small independent states recognised by larger states. According to the qualitative definition suggested by Zbigniew Dumieński (2014), microstates can also be viewed as "modern protected states, i.e. sovereign states that have been able to unilaterally depute certain attributes of sovereignty to larger powers in exchange for benign protection of their political and economic viability against their geographic or demographic constraints."[2]
In line with this definition, only Andorra, Liechtenstein, Monaco, and San Marino qualify as "microstates" as only these states are sovereignties functioning in close, but voluntary, association with their respective larger neighbours. Luxembourg, which is far larger than all the European microstates combined, nonetheless shares some of these characteristics.[3]
