The English depended on slaves for chipping away at their manors, particularly in the South. In the Triangular Trade, products were transported to Africa to be exchanged for slaves. ... The Portuguese had help catching African slaves from other African gatherings.
Historically the particular routes were also shaped by the powerful influence of winds and currents during the age of sail. For example, from the main trading nations of Western Europe, it was much easier to sail westwards after first going south of 30 N latitude and reaching the so-called "trade winds"; thus arriving in the Caribbean rather than going straight west to the North American mainland. Returning from North America, it is easiest to follow the Gulf Stream in a northeasterly direction using the westerlies. A triangle similar to this, called the volta do mar was already being used by the Portuguese, before Christopher Columbus' voyage, to sail to the Canary Islands and the Azores. Columbus simply expanded this triangle outwards, and his route became the main way for Europeans to reach, and return from, the Americas.
Atlantic triangular slave trade See also: Atlantic slave trade and Slave Coast of West Africa The best-known triangular trading system is the transatlantic slave trade that operated from Bristol, London, and Liverpool. during the late 16th to early 19th centuries, carrying slaves, cash crops, and manufactured goods between West Africa, Caribbean or American colonies and the European colonial powers, with the northern colonies of British North America, especially New England, sometimes taking over the role of Europe. The use of African slaves was fundamental to growing colonial cash crops, which were exported to Europe. European goods, in turn, were used to purchase African slaves, who were then brought on the sea lane west from Africa to the Americas, the so-called Middle Passage. Despite being driven primarily by economic needs, Europeans sometimes had a religious justification for their actions. In 1452, for instance, Pope Nicholas V, in the Dum Diversas, granted to the kings of Spain and Portugal "full and free permission to invade, search out, capture, and subjugate the Saracens [Muslims] and pagans and any other unbelievers ... and to reduce their persons into perpetual slavery."
Turner's main point in his thesis was that the frontier played the most significant part in American History and that majority of history took place around the colonization of the West.
His arguments are considered innacurate because what mostly dominates American History are the Civil War, industrialization, slavery and immigration. He also ignores the existance of native americans who lived out of the settled area.
The Arabian Peninsula is bordered by the Red Sea to the west and southwest, the Persian Gulf to the northeast, and the Indian Ocean to the southeast. It became like this because of a rift that happened with the Red Sea many years ago.
The Edict of Serdica was issued in 311 by the Roman emperor Galerius, officially ending the Diocletianic persecution of Christianity in the East. With the passage in 313 AD of the Edict of Milan, persecution of Christians by the Roman state ceased.
