A Flag Flies for Cuban Annexation
In May 1850, The Sun newspaper hoisted a never-before-seen Cuban flag from its building in lower Manhattan, timing it to coincide with the launching of a privately-organized military expedition to Cuba by the anti-Spanish separatist Narciso López. Sympathetic New Yorkers outfitted and accompanied López on his three attempts to liberate the island by force. The Spanish eventually executed López and his men, but the cause attracted supporters like the political writer John O’Sullivan, who believed that Anglo-Saxon Americans were destined to rule the North American continent (he coined the term “Manifest Destiny”), and Jane Cazneau, who edited The Sun and the bilingual Cuban separatist paper La Verdad from theSun building.
The 1840s and ‘50s were the high point of a campaign by many Cubans and North Americans to convince the U.S. to annex Cuba by peaceful or military means. Presidents Polk and Pierce tried unsuccessfully to purchase the valuable island but chose not to risk war with Spain by attempting annexation.
