The record behind the story
Evidence for
Four Months to Leave
Investigative question
How did the crowns of Castile and Aragon turn religious uniformity into an administrative deadline that forced Jewish residents to choose between baptism and departure?
Event boundary
The story runs from the decree signed March 31, 1492 through its implementation that summer, with earlier segregation and the Inquisition included only as necessary context. It does not conflate the later coerced conversion of Muslims, Portugal, Navarre, Sicily, or every territory later ruled by the Spanish monarchy.

Claim ledger
| ID | Claim | Status | Support | Qualification |
|---|---|---|---|---|
| C1 | Ferdinand and Isabella signed the decree March 31, 1492; it was promulgated in Castile in May. | supported | S1, S2 | Distinguish signing from public promulgation. |
| C2 | The order required Jews to leave the relevant kingdoms by the end of July and prohibited return. | supported | S1 | Scope the kingdoms precisely. |
| C3 | The stated justification was alleged Jewish influence on baptized Christians suspected of practising Judaism. | supported as decree's rationale | S1 | This is the crown's allegation, not an established fact. |
| C4 | The decree followed an earlier attempt to segregate Jewish residents in separate quarters. | supported | S1 | The decree itself invokes the 1480 policy. |
| C5 | Conversion was the practical alternative to departure, and conversion also made return possible for some exiles. | supported | S7, S8 | Distinguish the decree's wording from the practical choice. |
| C6 | Departing families could sell property, but the deadline and export rules constrained how sale proceeds could be carried abroad. | supported | S1, S2 | Avoid universal-confiscation claims or an unsupported forced-conversion mechanism. |
| C7 | Implementation generated pressured property transactions and royal measures concerning unsettled debts. | supported | S2, S9 | Present documented mechanisms, not a complete national picture. |
Duplicate boundary
Legacy entries about the Inquisition, conversos, Sephardic exile and Muslim expulsions overlap but are not promoted. Fingerprint: `castile-aragon:jewish-expulsion-decree-implementation:1492`. Later purity-of-blood rules and Morisco expulsions require separate stories.
Ethical and language boundary
Use Jewish residents or Jewish communities, not a single undifferentiated “Spanish Jewry.” Do not romanticize medieval coexistence as uniformly harmonious or portray expulsion as voluntary migration. Attribute the decree's accusations to its authors. Avoid exact population totals unless a range and scholarly disagreement are necessary.
What the record establishes
The decree and historical scholarship establish the expulsion order, its timetable and its coercive consequences. Estimates and individual experiences vary across the surviving record, so the story does not present a single disputed population figure as exact.
