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."
The internal and external factors that contributed to the collapse of the
Roman and Chinese empires were as follows:
Internal factors -
excessively expensive and overextended compared to the existing resources.
neither had technology advances that increased available resources.
Both were victims of tax avoidance by landowner families who absolved the poor from paying taxes.
Instability was brought on by antagonism between elite factions in both cases.
Both were affected by epidemics.
External factor -
Both empires' frontier territories were inhabited by nomadic nomads who grew to be increasingly dangerous and eventually captured parts of both empires.
<h3>Why did the Roman and Chinese empires collapse?</h3>
The fall of the Roman Empire had a number of causes. Each was woven into the other. Many people even attribute the rise of Christianity to the fall. Many Roman inhabitants became pacifists as a result of Christianity, making it harder to repel the barbarian invaders. Additionally, the Roman empire could have been maintained with the money invested to construct churches.
Han China's downfall was primarily brought on by the government's inability to run the country effectively. The bureaucrats became corrupt and prioritized pleasure over their jobs. The empire saw epidemics and nomadic insurgencies, yet government spending increased because political officials led extravagant lifestyles.
