James Marie-Antoine Monjaret de Kerjégu (27 February 1846 – 23 December 1908), French diplomat and politician, was born in Trévarez-Saint-Goazec (Finistère) to an ancient Breton family; his father, François-Marie Jacques de Kerjégu, was a member of the Chamber of Deputies and later a senator; two of his uncles had also been members of parliament.
He then returned to the diplomatic service, occupying posts in Germany, Serbia, Russia, and Switzerland.
A committed republican, he was dedicated to law and order and governmental stability.
He concerned himself particularly with economic and agricultural issues, and supported progressive causes, including welfare and public disability insurance.
On the other hand, he opposed the progressive income tax and the separation of church and state, and he favoured a strong military.
