An alternative approach, that may overcome these challenges, is to define microstates as "modern protected states". According to the definition proposed by Dumienski (2014): "microstates are 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." Adopting this approach permits limiting the number of microstates and separating them from both small states and autonomies or dependencies. Examples of microstates understood as modern protected states include such states as Liechtenstein, San Marino, Monaco, Niue, Andorra, the Cook Islands or Palau.
