During the turbulent 1940s, Baghdadi Jews, as well as many European Jews fleeing Nazi oppression, fled to the ‘City of Joy’ and found refuge there. They settled down and finally excelled in all of their endeavors, contributing significantly to the city’s commercial and cultural activities.
Kolkata (formerly “Calcutta” until 2001) became their ‘home,’ and the community became deeply ingrained in its fabric – until social, economic, and political factors forced them to relocate to countries with better prospects, such as the United States, the United Kingdom, Canada, Australia, and Israel.
It is believed that transitioning to a new country is akin to an Indian bride leaving her maternal home to live with her spouse in that one must change and forget certain things.
