This essay, which stems from a broader project on religion in the nineteenth-century Hispanic Caribbean, seeks to recreate the experiences of the thousands of Protestants who struggled tenaciously to retain or hide their faith in colonial Cuba and Puerto Rico before the declaration of religious tolerance in 1869 and before the establishment of the region's first Protestant churches, the Anglican congregation of Ponce, organised in 1869, the Episcopal mission of Havana, started in 1871, and the Anglican congregation of Vieques, an island located eight miles off the coast of Puerto Rico, founded in 1880.
