Examples of sovereignty include any state or nation that is independent, or under their own authority, such as the United States or Brazil. Sovereignty is defined as all persons and property within the borders of the state being under the exclusive authority of that state, explains Dictionary.com.
Being a sovereign state means that no outside entity can rightfully demand any internal action of the state government, says Globalization 101. For example, if Brazil wished to create an amusement park using a rainforest's material and land then no other country would be able to outright tell them to stop because of Brazil's sovereignty rights.
There are 195 sovereign states in the world as of July 9, 2011, reports One World Nations Online, when South Sudan became an independent state. Before that, the last changes occurred with the end of the State Union of Serbia and Montenegro in 2006 and the two nations emerged as independent states. All 11 sovereign nations of the world are also members of the United Nations, according to One World Nations Online. Included among the 11 non-member states are the Holy See (Vatican City State), Palestinian Territories (Gaza Strip and West Bank), South Sudan, Taiwan and Tibet.
