E C Ballard has posted an interesting article discussing Freemasonry in Cuba on his blog. From the article:
Cuban Freemasonry is unique in the world for operating openly in a communist nation. What can explain that, given that in most other communist nations Freemasonry has been condemned? For that answer, it is necessary to look at the role that Freemasonry played in the original Cuban Revolution or as some people speculate. the affiliation of the Castro brothers themselves?
Cuba is the only country under the administration of a Marxist government that tolerates throughout its territory an important secret society with an esoteric background: Freemasonry. Today, in the beautiful and economically challenged island of Martí and Maceo, no less than 318 Masonic lodges flourish, openly attended by about 30,000 registered members. Such numbers are high for a country with so small a population as that of Cuba. Various Afro-Cuban religions, Palo Congo, Yoruban Ocha, Abakua, and Haitian Vodú among the population of Haitian descent mostly in Eastern Cuba, religions often mistakenly dubbed “santería” – the Cuban first cousins of Brazilian Candomblé and Umbanda also exist in Cuba, the only other power system capable of competing with esoteric Freemasonry in terms of being reasonably free and unrestricted.
