Hello I would like to learn about Cuba please.
Sure not a problem I can help with that...... Cuba is an island country in the Caribbean Sea. The country is made up of the big island of Cuba, the Isla de la Juventud Island (Island of Youth) and many smaller islands. Havana is the capital of Cuba.
Can you tell me a little about the etymology?
Absolutely......Fringe theory writers who believe that Christopher Columbus was Portuguese state that Cuba was named by Columbus for the town of Cuba in the district of Beja in Portugal.
That is interesting, can you tell me anything else about that?
At the moment I do not have any other facts about the etymology....I can share this however, ......Cuba is the only communist state outside of Asia in the Caribbean and in the western hemisphere.
I didn't realize that no other country in the western hemisphere was not communist. Can you tell me anything about the education?
I do not have anything on the education at the moment. Some interesting history though.....Several members of the Communist Party held office under his administration.
Can you tell me anything else about the history?
Castro's legalization of the Communist party and the hundreds of executions of Batista agents, policemen and soldiers that followed caused a deterioration in the relationship between the two countries.
Can you tell me one fun fact? Maybe something upbeat?
Before Fidel Castro's 1959 revolution, Cuba was one of the most advanced and successful countries in Latin America.
Thank you for the new things I learned today.
Glad i could help.
