In 1740, Parliament passed the Plantation Act specifically permitting Jews to be naturalized in the colonies. Previous to this date, however, the New York Colonial Assembly had passed numerous special acts of naturalization, some of which were applicable to individuals only; others, more general in character, under which Jews could be naturalized without taking oath "upon the true faith of a Christian," were also put upon the statute-book. Between this time and the Revolutionary War the Jewish community in this colony increased by slow stages, the principal immigrants coming from Spain, Portugal, and the West Indies.
