A marionette government refers to a political system where a government is controlled by an external power, rather than operating independently. This external influence often manipulates the government’s decisions and policies, making it act in the interests of the controlling entity rather than its own citizens. Such governments are often seen in situations where a foreign nation or organization exerts significant influence over a country's political affairs. This can lead to a lack of true sovereignty for the nation, as the government functions more like a puppet, responding to the demands of its puppet master.
