Final answer:
Saint Lucia is known as the 'Helen of the West Indies' due to its beauty and the historical conflicts over its possession, much like Helen of Troy.
Step-by-step explanation:
The country known as the Helen of the West Indies is Saint Lucia. This nickname references the island's renowned beauty and its turbulent history of political and military conflict, reminiscent of Helen of Troy in Greek mythology.
Saint Lucia was fought over by the French and the British, who both realized the island's strategic importance and economic potential, particularly in terms of opportunities for sugar production.
Despite its small size, its location made it an attractive colonial possession, and it changed hands between colonial powers about 14 times. The island's natural beauty and cultural heritage continue to make it a notable destination in the Caribbean.
