Andreas N. Stratos (Greek: Ανδρέας Ν. Στράτος; 1905 – 30 August 1981) was a distinguished Greek lawyer, politician and historian. The son of politician and Prime Minister of Greece Nikolaos Stratos, he was elected a member of the Hellenic Parliament continuously from 1932 to 1961, he served five times in cabinet posts as Minister for Labour (1946, 1954–55), Minister Governor-General of Northern Greece (1952–54) and Minister of Health and Social Welfare (1958–61, 1961–62). At the same time, he was actively interested in the study of the Byzantine Empire, and following his retirement from politics dedicated himself to writing the six-volume Byzantium in the 7th Century (Το Βυζάντιον στον Ζ' αιώνα, 1965–77), the first comprehensive study of the Byzantine state during this critical period in its history.
Andreas Stratos was born in Athens in 1905, the son of Nikolaos Stratos and Maria Koromila. In November 1922, his father was tried and executed by the military government as one of those principally responsible for the Greek defeat against Turkey in the so-called "Asia Minor Disaster". In the virulent political atmosphere of the time, 17-year-old Andreas fled with his mother and sister, Dora, to Germany. The family was in dire financial situation, despite some help from his grandmother and Nikolaos Kalogeropoulos, forcing his mother to seek employment as a soprano singer as well as a dressmaker in various fashion designers. Andreas was able to study in law and political sciences at the universities of Jena, Berlin, and Paris, where he also studied music in a conservatory.
