Zinovios Zafirios I. Valvis (Greek, Modern (1453-);: Ζηνόβιος-Ζαφείριος Ι. Βάλβης; 1800 – 25 August 1886) was a Greek politician and Prime Minister of Greece. Valvis was born in 1800 in Missolonghi.[1] He first studied theology at the Theological School of Halki[2] but switched to law, furthering his studies in Pisa, Italy.[3] [4] Valvis married Arsinoe Ratzikosta and fathered nine children. He twice served as prime minister but fell on hard times in his old age, dying impoverished in 1872 after refusing a state pension so as not to be a burden on the Greek state. Zinovios Valvis was the brother of Dimitrios Valvis who also served as Prime Minister. He died in Missolonghi in 1886.
