In June 1941, Romania entered
World War II on the side of the
Axis and soon after re-established control over Bessarabia and Northern Bukovina. Military dictator
Ion Antonescu requested him to become mayor of Cernăuți, but Popovici initially refused, unwilling to serve a
fascist government. He changed his mind, however, based on advice from his friends. A few days after acceptance, in early August 1941, he was ordered by , the Governor-General of
Bukovina, to create a
ghetto for the Jews of Cernăuți, but Popovici refused to accept that part of the city's population could be confined behind
barbed wire fences. On August 30, 1941, Rioșanu died after an unsuccessful surgery, and he was succeeded as governor by General
Corneliu Calotescu. On October 10, Calotescu announced his decision that all the Jews of Cernăuți must be
deported to
Transnistria. After a long debate, Calotescu allowed Popovici to nominate 200 Jews who were to be exempted from deportation. Unsatisfied with the modest concession, Popovici tried reaching Antonescu himself, this time arguing that Jews were of capital importance to Cernăuți's economy and requested a postponement until replacements could be found. As a result, he was allowed to expand the list, which covered 20,000 Jews in its final version. Popovici died in 1946 in the village of Colacu (part of
Fundu Moldovei commune, in
Suceava County), and was buried in the churchyard of the village, next to the . Due to Popovici's defense of Jews, his political adversaries nicknamed him "
jidovitul" ("the turned-Jewish"). ==Legacy==
