Jews started living in
Ancona, Italy around A.D. 967. In that year, the
Archbishop of Ravenna rented a piece of land to a
Jew named Eliyahu. It is possible that a
synagogue existed already in the 12th century, due to a
Slicha written by a
Jewish Paytan, referring the 1279 destruction of the town synagogue by an
earthquake. In 1427 Saint
James of the Marches unsuccessfully tried to force town Jews to wear a
Jewish badge and restrict them into one street, though opinions are not unanimous regarding this unsuccessful attempt, claiming Jews were forced to carry a Jewish badge and live in restricted areas. In 1520, the Jews of Ancona were forced once again to wear the Jewish badge, though this rule had been cancelled four years later. In around 1450, the Jewish population of Ancona numbered an estimated 500 persons, consisting of 5% of the town's total population. After the city had fallen into the Papal state in 1429, Pope
Martin V tried to develop Ancona as an Italian center of commerce. In order to achieve that goal, the town Jews got permission to open
banks and loan money by interest. Due to this pro-Jewish approach, Jewish fugitives from the
Spanish Inquisition (started in 1492) began to settle in Ancona and changed the demographics and the ratios between the sub-groups of the town Jewish community. Most of these fugitives came from
Sicily and later from
Naples and
Portugal. In 1529, the Jewish
false messiah Shlomo Molkho visited Ancona and provoked and stimulated a messianic enthusiasm among the town Jews. As Ancona was declared a free port in around 1532 by
Pope Paul III, the city was joined by even more
Spanish and
Portuguese Jews who found it to be an ideal base for commerce with the
Levant. In 1550, the Jewish population of Ancona numbered about 2700 individuals. The pro-Jewish attitude of the Roman Popes protected and stimulated the growth of the Ancona Jewish population, until 1555 when the
Vatican approach towards the Ancona Jews had changed due to the persecutions of Pope
Paul IV in 1555. ==Persecution under Pope Paul IV==
