Arabia Felix (lit. Happy Arabia; also Greek: Eudaimon Arabia) was the Latin name previously used by geographers to describe the southern parts of the Arabian Peninsula, including modern Yemen, a country with an extensive history.[1]
The term "Happy Arabia" is a translation of the Latin "Arabia felix." Felix means "happy, fortunate, blessed."
The southwestern corner of the peninsula, enjoying more rainfall, is much greener than the rest of the peninsula and has long enjoyed more productive fields. The high peaks and slopes are capable of supporting significant vegetation and river beds called wadis help make other soil fertile.
In 26 BC Aelius Gallus under Augustus's order led a military expedition to Arabia Felix which ended in the utter defeat of Roman troops.
Part of what led to Arabia Felix's wealth and importance to the ancient world was its near monopoly of the trade in cinnamon and spices, both its native products and imports from India and the Horn of Africa. [2]
