In Gallinas, Pedro Blanco built himself a private kingdom with storehouses on an island, his office on another island, and houses for his African wives on yet a third island. Slaves awaiting shipment were housed on the islands of Taro and Kamasun. In 1838, Blanco left Africa for Cuba and went to Barcelona, all the time trading in slaves. He left Gallinas just before most of the La Amistad Africans reached his stockades, but he left behind a network of employees to continue his business. It is likely that some of them handled the Amistad Africans. At any rate, he played a vital part in the development of the slave trade in this region. Blanco's business finally collapsed in 1848, and in 1854 he died in Genoa .
