Types of Sovereignty
De-facto sovereign is one who has no legal claim to sovereignty but possesses it in fact and exercises necessary force to make and enfore its laws.
De-jure sovereign is one who has a legal claim to sovereignty but does not possess it in fact.
Napoleon became the de facto sovereign after he had over thrown the directory. Franco became the de facto sovereign after he had dislodged the legal sovereign in Spain after Mussolini’s black shirt march on October 28, 1922. Mussolini became the prime minister in the legal manner. He ruled the parliament and ruled the country through parliament. Parliament remained the legal sovereign but he was the actual or de facto sovereign. Hitler also did the same in Germany. He controlled the legal sovereign and became the de facto sovereign.
For three decades, Stalin remained the actual sovereign in USSR. Military coup in Pakistan by Ayub reflects de facto sovereign. In 1977 when Zia-Ul-Haq over threw Bhutto, first he became de facto and later de jure sovereign. At times it happens that the de facto and de jure sovereignty ultimately coincide. Communist Government in Soviet Union became the de facto Government of the successful Bolshevik Revolution in 1917. But in course of time, it became the de jure government also.
