Emigré Judeo-Portuguese developed in the early sixteenth century in
places where the Portuguese Marranos re-assumed Judaism and developed flourishing Jewish communities: Northern Germany, Holland, France, Italy, England, the Caribbean, and North and South America.
Judeo-Portuguese was called the language of the Portuguese Nation (Nação Portuguesa) and was the official language spoken and written in the diaspora communities. In Western Europe it was used in numerous domains: the home, commercial transactions, administration, formal ceremonies, greetings, sermons, speeches, legal exchanges, registrations, tomb inscriptions, community reports, etc. Only after 1850, with the introduction of public schools, did its use diminish, becoming limited to home use, sometimes only on the Sabbath.
