Quisqueya, A History of the Dominican Republic, by Selden Rodman (HC, 1964, ex-lib., 1964)
Quisqueya is the native name of the island containing both the Dominican Republic and Haiti. This book is mostly about the Dominican Republic.
The Dominican Republic is known to be a far better place to live in than Haiti, but that is only because Haiti is one of the world's worst... and that was before the earthquake struck. This book was written in 1964 when Trujillo had been assassinated, and Bosch overthrown. There is hope of better times to come. But in 1965 President Johnson sends in the Marines to keep the Dominican Republic from becoming "another Cuba". Oh, well.
Read here about the Dominican Republic's history from the coming of the Europeans to the overthrow of Bosch. Look for this in the Caribbean history section.
