Ο Rene Viviani (René Viviani, 1862-1925) was a French politician and Prime Minister, known for his progressive political activity and his role in the First World War. He was born on 8 November 1863 in Algeria, which was then a French colony. He studied law and initially practised as a lawyer, defending progressive and labour causes.

He was a member of the Socialist Party, but later distanced himself from it and followed more centrist positions. In 1906 he was appointed Minister of Labour and implemented important social reforms, such as improving working conditions. In 1914 he became Prime Minister, forming the government called upon to manage the start of World War I. At the same time, he held the post of Foreign Secretary. He played a central role in the national unity of France during the war crisis, but resigned in 1915 due to political pressure. After the war, he continued to serve in various political positions.

He was initiated into Freemasonry in 1894 in the lodge “Les Droits de l’Homme”, under the auspices of the Grand Orient de France, the leading Masonic jurisdiction in France, known for its progressive and secular ideas. His affiliation with Freemasonry reinforced his commitment to the values of democracy and social progress at a time when he was playing an important role in shaping political and social reforms in France.

His lodge was closely tied to Republican values, promoting secularism, public education and social justice, values that resonated with Viviani’s political stance as a Socialist and later as a government official. As the first Prime Minister of France during World War I (1914-1915), his Masonic principles likely influenced his commitment to the principles of liberty, equality, and fraternity that guided many of his policies and approach to war management.

He died in 1925 in Paris.
