Tsereteli was born and raised in Georgia when it was part of the Russian Empire. A member of the Menshevik faction of the RSDLP, Tsereteli was elected to the Duma in 1907, where he gained fame for his oratory abilities. Shortly after entering the Duma, Tsereteli was arrested and charged with conspiracy to overthrow the Tsarist government, and exiled to Siberia. A dedicated Social Democrat who believed in the Menshevik ideology, Tsereteli was one of the leading figures of the movement in Russia. In 1915, during his Siberian exile, Tsereteli formed what would become known as Siberian Zimmerwaldism, which advocated for the role of the Second International in ending the war. He also developed the idea of "Revolutionary Defensism", the concept of a defensive war which only allowed for the defence of territory, and argued it was not being utilized.
