The French Third Republic (French: Troisième République, sometimes written as La IIIe République) was the system of government adopted in France from 4 September 1870, when the Second French Empire collapsed during the Franco-Prussian War, until 10 July 1940, after the Fall of France during World War II led to the formation of the Vichy government. The French Third Republic was a parliamentary republic.
The early days of the French Third Republic were dominated by political disruption caused by the Franco-Prussian War of 1870–1871, which the Third Republic continued to wage after the fall of Emperor Napoleon III in 1870. Social upheaval and the Paris Commune preceded the final defeat. The German Empire, proclaimed by the invaders in the Palace of Versailles, annexed the French regions of Alsace (keeping the Territoire de Belfort) and Lorraine (the northeastern part, i.e. present-day department of Moselle). The early governments of the French Third Republic considered re-establishing the monarchy, but disagreement as to the nature of that monarchy and the rightful occupant of the throne could not be resolved. Consequently, the Third Republic, originally envisioned as a provisional government, instead became the permanent form of government of France.
The French constitutional laws of 1875 defined the composition of the Third Republic. It consisted of a Chamber of Deputies and a Senate to form the legislative branch of government and a president to serve as head of state. Calls for the re-establishment of the monarchy dominated the tenures of the first two presidents, Adolphe Thiers and Patrice de MacMahon. However, growing support for the republican form of government among the French populace and a series of republican presidents in the 1880s gradually quashed prospects of a restoration with the republic being seen as, in the words of Thiers, "the form of government that divides us the least".
The Third Republic established many French colonial possessions, including French Indochina, French Madagascar, French Polynesia, and large territories in West Africa during the Scramble for Africa, all of them acquired during the last two decades of the 19th century. The early years of the 20th century were dominated by the Democratic Republican Alliance, which was originally conceived as a centre-left political alliance, but over time became the main centre-right party. The period from the start of World War I to the late 1930s featured sharply polarized politics, between the Democratic Republican Alliance and the Radicals. The government fell less than a year after the outbreak of World War II, when Nazi forces occupied much of France, and was replaced by the rival governments of Charles de Gaulle's Free France (La France libre) and Philippe Pétain's French State (L'État français).
During the 19th and 20th centuries, the French colonial empire was the second largest colonial empire in the world only behind the British Empire; it extended over 13,500,000 km2 (5,200,000 sq mi) of land at its height in the 1920s and 1930s. Journalist Raymond Recouly wrote in 1931 that of all the Powers in Europe, only France could offer both a substantial metropolitan and colonial military career. In terms of population however, on the eve of World War II, France and its colonial possessions totaled only 150 million inhabitants, compared with 330 million for British India alone.
Adolphe Thiers called republicanism in the 1870s "the form of government that divides France least"; however, politics under the Third Republic were sharply polarized. On the left stood reformist France, heir to the French Revolution. On the right stood conservative France, rooted in the peasantry, the Catholic Church, and the army. In spite of France's sharply divided electorate and persistent attempts to overthrow it, the Third Republic endured for 70 years, which makes it the longest-lasting system of government in France since the collapse of the Ancien Régime in 1789.
The Franco-Prussian War of 1870–1871 resulted in the defeat of France and the overthrow of Emperor Napoleon III and his Second French Empire. After Napoleon's capture by the Prussians at the Battle of Sedan (1 September 1870), Parisian deputies led by Léon Gambetta established the Government of National Defence as a provisional government on 4 September 1870. The deputies then selected General Louis-Jules Trochu to serve as its president. This first government of the Third Republic ruled during the Siege of Paris (19 September 1870 – 28 January 1871). As Paris was cut off from the rest of unoccupied France, the Minister of War Léon Gambetta succeeded in leaving Paris in a hot air balloon, and established the provisional republican government in the city of Tours on the Loire river.
After the French surrender in January 1871, the provisional Government of National Defence disbanded, and national elections were called to elect a new French government. French territories occupied by Prussia at the time did not participate. The resulting conservative National Assembly elected Adolphe Thiers head of a provisional government, ("head of the executive branch of the Republic pending a decision on the institutions of France").
The new government negotiated a peace settlement with the newly proclaimed German Empire: the Treaty of Frankfurt signed on 10 May 1871. To prompt the Prussians to leave France, the government passed a variety of financial laws, such as the controversial Law of Maturities, to pay reparations.
In Paris, resentment built against the government from late March through May 1871. Paris workers and National Guards revolted and took power as the Paris Commune, which maintained a radical left-wing regime for two months until the Third government bloodily suppressed it in May 1871. The ensuing repression of the communards had disastrous consequences for the labour movement.
Attempts to restore the monarchy
The French legislative election of 1871, held in the aftermath when the regime of Napoleon III collapsed, resulted in a monarchist majority in the French National Assembly that favoured a peace agreement with Prussia. Planning to restore the monarchy, the "Legitimists" in the National Assembly supported the candidacy of Henri, Comte de Chambord, alias "Henry V", grandson of King Charles X, the last king from the senior line of the Bourbon dynasty. The Orléanists supported Louis-Philippe, Comte de Paris, a grandson of King Louis Philippe I, who replaced his cousin Charles X in 1830. The Bonapartists lost legitimacy due to the defeat of Napoléon III and were unable to advance the candidacy of any member of the Bonaparte family.
Legitimists and Orléanists eventually agreed on the childless Comte de Chambord as king, with the Comte de Paris as his heir. This was the expected line of succession for the Comte de Chambord based on France's traditional rule of agnatic primogeniture if the renunciation of the Spanish Bourbons in the Peace of Utrecht was recognised. Consequently, in 1871 the throne was offered to the Comte de Chambord.
Monarchists' republic and constitutional crisis
Chambord believed the restored monarchy had to eliminate all traces of the Revolution (most famously including the tricolore), to restore unity between the monarchy and the nation. Compromise on this was impossible, Chambord believed, if the nation were to be made whole again. The general population, however, was unwilling to abandon the Tricolour flag. Monarchists therefore resigned themselves to delay the monarchy until the death of the ageing, childless Chambord, then to offer the throne to his more liberal heir, the Comte de Paris. A "temporary" republican government was therefore established. Chambord lived on until 1883, but by that time, enthusiasm for a monarchy had faded, and the Comte de Paris was never offered the French throne.
Following the French surrender to Prussia in January 1871, concluding the Franco-Prussian War, the transitional Government of National Defence established a new seat of government at Versailles due to the encirclement of Paris by Prussian forces. New representatives were elected in February of that year, constituting the government which would come to evolve into the Third Republic. These representatives – predominantly conservative republicans – enacted a series of legislation which prompted resistance and outcry from radical and leftist elements of the republican movement. In Paris, a series of public altercations broke out between the Versailles-aligned Parisian government and the city's radical socialists. The radicals ultimately rejected the authority of Versailles, responding with the foundation of the Paris Commune in March.
