The return of the Nation: the Portuguese anusim open Amsterdam

From the 1590s Portuguese New Christians appear in the Amsterdam notarial records — as Portuguese Catholics with Catholic names, trading in Iberian and Atlantic commodities. The passage to open Jewish life was gradual, contested and almost undocumented before about 1602.

What is documented: on 14 September 1603 Moses Uri Halevi, of Emden, was arrested at Amsterdam — the Dutch archival record gives the charge as receiving stolen goods; he was released. About 1601–02 Moses Uri Halevi and his son Aaron settled in the city: the father officiating in Ashkenazi Hebrew and Yiddish, the son translating for the conversos into Spanish and Portuguese.

The congregations formed one after another: Beth Jacob — the date disputed, anywhere from 1596 to 1610; Neve Shalom about 1608; Beth Israel in 1618. The cemetery at Ouderkerk aan de Amstel was bought in April 1614. In 1615 the Santa Companhia de dotar dowry society was founded, in 1616 the Talmud Torah educational confraternity, in 1622 the joint Imposta board for taxation and charity.

The famous story — the neighbours mistaking a converso service for a Catholic mass, the *schout* bursting in on Yom Kippur, the Jews arrested, a Portuguese explaining to the magistrates in Latin that they were Jews and not papists — has one source: the family chronicle Narração, written about 1673 by Moses Uri's grandson and printed in 1710–11, together with Daniel Levi de Barrios's verse chronicle of 1683. This is ancestral apologetics composed seventy to a hundred and ten years after the events, and the Dutch reference work on Jewish history says plainly that these are not sources for a historical account. Two incompatible versions circulate even inside the tradition — the raid falls on Yom Kippur in one and on Simhat Torah in the other.

But the date should not be thrown out either, and here precision pays: the one documented arrest of Moses Uri Halevi is of 14 September 1603, which is 9 Tishri, the eve of Yom Kippur. So the legend's liturgical setting is chronologically possible; what the archive does not support is the charge — it records receiving stolen goods, not unlawful assembly — and the years "1596" and "the 1590s."

One more thing that circulates online: "sixteen Portuguese Jews kept Yom Kippur at the house of Samuel Pallache in 1593." Pallache did not reach the Republic until 1608–09, as Moroccan envoy, and died at The Hague on 4 February 1616; he can have had nothing to do with a service of 1593 or 1596.
