Victor Ambroise, vicomte de Lanjuinais, was born in Paris on 5 November 1802. His father was
Jean Denis, comte Lanjuinais (1753–1827). His brother was Paul-Eugène Lanjuinais (1799–1812 ), a peer of France. Victor Lanjuinais studied law and was admitted to the bar. He was a friend of
Gustave d'Eichthal, an author who was sympathetic to Africans and advocated mixed marriages to produce offspring with the complementary qualities of the black and white races. When
John Stuart Mill visited Paris in 1830 he spent much time with Lanjuinais and Eichthal, finding the views of these young men refreshing and encouraging. Lanjuinais edited a multi-volume collection of the works of his father, and contributed a biographical preface to the work in 1832. On 17 February 1838 Victor Lanjuinais was elected deputy for the third college of
Loire-Inférieure (Pont-Rousseau). He sat on the center-left. He was reelected in March 1839, July 1842 and August 1846. He was a correspondent of the liberal thinker
Alexis de Tocqueville. Lanjuinais belonged to a small group of deputies who followed Tocqueville in supporting the
Orleans monarchy while agitating for democratic reforms. He was moderately opposed to the policy of
François Guizot, and voted for the electoral reform proposal in 1847, but refused to join the
Campagne des banquets (banquet campaign). ==Second Republic==
