These changes also entailed the rise of labour movements. The first Cuban labour organization, the Cigar Makers Guild, was created in 1878, followed by the Central Board of Artisans in 1879, and many more across the island. Abroad, a new trend of aggressive American influence emerged, evident in Secretary of State James G. Blaine's expressed belief that all of Central and South America would some day fall to the US. Blaine placed particular importance on the control of Cuba. "That rich island", he wrote on 1 December 1881, "the key to the Gulf of Mexico, is, though in the hands of Spain, a part of the American commercial system…If ever ceasing to be Spanish, Cuba must necessarily become American and not fall under any other European domination". Blaine's vision did not allow the existence of an independent Cuba.
