Typically, parliamentary republics are states that were previously
constitutional monarchies with a parliamentary system. Following the defeat of
Napoleon III in the
Franco-Prussian War, France again became a republic – the
French Third Republic – in 1870. The President of the Third Republic had significantly less executive powers than those of the previous two republics had. The Third Republic lasted until the
invasion of France by Nazi Germany in 1940. Following the end of the war, the
French Fourth Republic was constituted along similar lines in 1946. The Fourth Republic saw an era of great economic growth in France and the rebuilding of the nation's social institutions and industry after the war, and played an important part in the development of the process of European integration, which changed the continent permanently. Some attempts were made to strengthen the executive branch of government to prevent the unstable situation that had existed before the war, but the instability remained and the Fourth Republic saw frequent changes in government – there were 20 governments in ten years. Additionally, the government proved unable to make effective decisions regarding decolonization. As a result, the Fourth Republic collapsed and Charles de Gaulle was given power to rule by decree, subsequently legitimized by approval of a new constitution in a referendum on 28 September 1958, which led to the establishment of the
French Fifth Republic in 1959.
Commonwealth of Nations Since the
London Declaration of 29 April 1949 (just weeks after
Ireland declared itself a republic and excluded itself from the Commonwealth), republics have been admitted as members of the Commonwealth of Nations. In the case of many
republics in the Commonwealth of Nations, it was common for the Sovereign, formerly represented by a
Governor-General, to be replaced by a non-executive head of state. This was the case in
South Africa (which ceased to be a member of the Commonwealth immediately upon becoming a republic, and later transitioned to having an executive presidency),
Malta,
Trinidad and Tobago,
India,
Vanuatu and since 30 November 2021,
Barbados. In many of these examples, the last Governor-General became the first president. Such was the case with
Sri Lanka and
Pakistan. Other states became parliamentary republics upon gaining independence. == List of modern parliamentary republics and related systems ==
