Biography.

Family background.Spinoza's ancestors, adherents of Crypto-Judaism, faced persecution during the Portuguese Inquisition, enduring torture and public displays of humiliation. In 1597, his paternal grandfather's family left Vidigueira for Nantes and lived outwardly as New Christians, eventually transferring to Holland for an unknown reason. His maternal ancestors were a leading Porto commercial family, and his maternal grandfather was a foremost merchant who drifted between Judaism and Christianity. Spinoza was raised by his grandmother from ages six to nine and probably learned much about his family history from her.
