Born in Anglès, in the Department of Tarn in southwest France. Elected (30 August 1791) as a representative of the Department of Tarn to the Legislative Assembly (1791–1792). Alba was elected (3 September 1792) to the National Convention (1792–1793) once again as a deputy for Tarn, and he developed ties with the Girondist faction.
He nevertheless voted for the death sentence in the trial of Louis XVI. He was sent on a mission to Nice, a city recently conquered by the French armies, and called its unification with France.
He made many powerful enemies, including Georges Danton, who he accused of complicity in the treason of General Dumouriez (1 April 1793). With the fall of the Girondists he was proscribed (2 June 1793) and removed from the Convention, and ultimately condemned to death by the revolutionary tribunal (30 October 1793).
