Officially known as the Republic of Poland or the Commonwealth of Poland, the Polish state was recreated in 1918, in the aftermath of World War I. When, after several regional conflicts, the borders of the state were fixed in 1922, Poland's neighbours were Czechoslovakia, Germany, the Free City of Danzig, Lithuania, Latvia, Romania and the Soviet Union.

Central America is bordered by Mexico to the north, Colombia to the southeast, the Caribbean Sea to the east, and the Pacific Ocean to the west. Central America consists of seven countries: Belize, Guatemala, El Salvador, Honduras, Nicaragua, Costa Rica and Panama.

The course led from the western Atlantic, around the southern tip of Africa, stopping at Madagascar, then on to targets such as the coast of Yemen and India.

Original buccaneer crews, however, were larger, localized to the Caribbean region, and more apt to attack well-defended ports than pirates who sailed to the Indian Ocean on the Pirate Round of the late 17th century., South America is a continent located in the western hemisphere, mostly in the southern hemisphere, with a relatively small portion in the northern hemisphere.
