Editing Baruch Spinoza (section)

===Family background===
{{see also|History of the Jews in Amsterdam}}

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]],{{sfn|Israel|2023|pp=85-87}} eventually transferring to Holland for an unknown reason.{{sfn|Israel|2023|p=134}} His maternal ancestors were a leading [[Porto]] commercial family,{{sfn|Israel|2023|p=88}} and his maternal grandfather was a foremost merchant who drifted between Judaism and Christianity.{{sfn|Israel|2023|p=299}} Spinoza was raised by his grandmother from ages six to nine and probably learned much about his family history from her.{{sfn|Israel|2023|p=124}}

Spinoza's father Michael was a prominent and wealthy merchant in Amsterdam with a business that had wide geographical reach.{{sfn|Israel|2023|p=158}} In 1649, he was elected to serve as an administrative officer of the recently united congregation [[Portuguese Synagogue (Amsterdam)|Talmud Torah]].{{sfn|Israel|2023|p=144}} He married his cousin Rachael d'Espinosa, daughter of his uncle Abraham d'Espinosa, who was also a community leader and Michael's business partner.{{sfn|Israel|2023|p=140}} Marrying cousins was common in the Portuguese Jewish community then, giving Michael access to his father-in-law's commercial network and capital.{{sfn|Israel|2023|p=140-41}} Rachel's children died in infancy, and she died in 1627.{{sfn|Nadler|2018|p=38}}{{sfn|Israel|2023|p=140-41}}

After the death of Rachel, Michael married Hannah Deborah, with whom he had five children. His second wife brought a dowry to the marriage that was absorbed into Michael's business capital instead of being set aside for her children, which may have caused a grudge between Spinoza and his father.{{sfn|Israel|2023|p=183}} The family lived on the artificial island on the south side of the River Amstel, known as the [[Vlooienburg]], at the fifth house along the [[Houtgracht]] canal.{{sfn|Israel|2023|p=115}} The Jewish quarter was not formally divided. The family lived close to the Bet Ya'acov synagogue, and nearby were Christians, including the artist [[Rembrandt]].{{sfn|Israel|2023|p=117}} Miriam was their first child, followed by Isaac who was expected to take over as head of the family and the commercial enterprise but died in 1649.{{sfn|Israel|2023|p=183}} '''Baruch Espinosa''', the third child, was born on 24 November 1632 and named as per tradition for his maternal grandfather.{{sfn|Nadler|1999|p=45}}

Spinoza's younger brother Gabriel was born in 1634, followed by another sister Rebecca. Miriam married [[Caceres family|Samuel de Caceres]] but died shortly after childbirth. According to Jewish practice, Samuel had to marry his former sister-in-law Rebecca.{{sfn|Israel|2023|p=185}} Following his brother's death, Spinoza's place as head of the family and its business meant scholarly ambitions were pushed aside.{{sfn|Israel|2023|p=158}} Spinoza's mother, Hannah Deborah, died when Spinoza was six years old. Michael's third wife, Esther, raised Spinoza from age nine; she lacked formal Jewish knowledge due to growing up a New Christian and only spoke Portuguese at home. The marriage was childless.{{sfn|Israel|2023|p=145-46}} Spinoza's sister Rebecca, brother Gabriel, and nephew eventually migrated to [[History of the Jews in Curaçao|Curaçao]], and the remaining family joined them after Spinoza's death.{{sfn|Israel|2023|p=185}}

====Uriel da Costa's early influence====

Through his mother, Spinoza was related to the philosopher [[Uriel da Costa]], who stirred controversy in Amsterdam's Portuguese Jewish community.{{sfn|Israel|2023|p=159}} Da Costa questioned traditional Christian and Jewish beliefs, asserting that, for example, their origins were based on human inventions instead of God's revelation. His clashes with the religious establishment led to his excommunication twice by rabbinic authorities, who imposed humiliation and social exclusion.{{sfn|Israel|2023|p=160}} In 1639, as part of an agreement to be readmitted, da Costa had to prostrate himself for worshippers to step over him. He died in 1640, reportedly committing suicide.{{sfn|Israel|2023|p=161}}

During his childhood, Spinoza was likely unaware of his family connection with Uriel da Costa; still, as a teenager, he certainly heard discussions about him.{{sfn|Israel|2023|p=90}} [[Steven Nadler]] explains that, although da Costa died when Spinoza was eight, his ideas shaped Spinoza's intellectual development. Amsterdam's Jewish communities long remembered and discussed da Costa's skepticism about organized religion, denial of the soul's immortality, and the idea that Moses didn't write the Torah, influencing Spinoza's intellectual journey.{{sfn|Nadler|2018|p=84}}
