Beginning of Negro Slavery in Europe.—At this point begins the horrible and revolting story of European Negro slavery. The ancient world had practiced this ownership of human chattels, and the Roman Empire had declined under a burden of half the population sunk in bondage. To the enormous detriment and suffering of mankind, Mohammed had tolerated the institution, and slavery is permitted by the Koran. But it is the glory of the mediæval church that it abolished human slavery from Christian Europe. However dreary and unjust feudalism may have been, it knew nothing of that institution which degrades men and women to the level of cattle and remorselessly sells the husband from his family, the mother from her child.

Slaves in Portugal.—The arrival of the Portuguese upon the coast of Guinea now revived not the bondage of one white man to another, but that of the black to the white. The first slaves carried to Portugal were regarded simply as objects of peculiar interest, captives to represent to the court the population of those shores which had been added to the Portuguese dominion. But southern Portugal, from which the Moors had been expelled, had suffered from a lack of laborers, and it was found profitable to introduce Negroes to work these fields.

Arguments to Justify Slavery.—So arose the institution of Negro slavery, which a century later upon the shores of the New World was to develop into so tremendous and terrible a thing. Curiously enough, religion was evoked to justify this enslavement of the Africans. The Church taught that these people, being heathen, were fortunate to be captured by Christians, that they might thereby be brought to baptism and conversion; for it is better for the body to perish than for the soul to be cast into hell. At a later age, when the falsity of this teaching had been realized, men still sought to justify the institution by arguing that the Almighty had created the African of a lower state especially that he might serve the superior race.

The coast of Guinea continued to be the resort of slavers down to the middle of the last century, and such scenes of cruelty, wickedness, and debauchery have occurred along its shores as can scarcely be paralleled in brutality in the history of any people.

The Portuguese can hardly be said to have colonized the coast in the sense of raising up there a Portuguese population. As he approached the equator the white man found that, in spite of his superior strength, he could not permanently people the tropics. Diseases new to his experience attacked him. His energy declined. If he brought his family with him, his children were few or feeble and shortly his race had died out.

The settlements of the Portuguese were largely for the purposes of trade. At Sierra Leone, Kamerun, or Loango, they built forts and established garrisons, mounting pieces of artillery that gave them advantage over the attacks of the natives, and erecting warehouses and the loathsome “barracoon,” where the slaves were confined to await shipment. Such decadent little settlements still linger along the African coast, although the slave-trade happily has ended.

The Successful Voyage of Vasco da Gama.—Throughout the century Prince Henry’s policy of exploration was continued. Slowly the middle coast of Africa became known. At last in 1486, Bartholomew Diaz rounded the extremity of the continent. He named it the Cape of Storms; but the Portuguese king, with more prophetic sight, renamed it the Cape of Good Hope. It was ten years, however, before the Portuguese could send another expedition. Then Vasco da Gama rounded the cape again, followed up the eastern coast until the Arab trading-stations were reached. Then he struck across the sea, landed at the Malabar coast of India, and in 1498 arrived at Calcutta. The end dreamed of by all of Europe had been achieved. A sea-route to the Far East had been discovered.

Results of Da Gama’s Voyage.—The importance of this performance was instantly recognized in Europe. Venice was ruined. “It was a terrible day,” said a contemporary writer, “when the word reached Venice. Bells were rung, men wept in the streets, and even the bravest were silent.” The Arabs and the native rulers made a desperate effort to expel the Portuguese from the Indian Ocean, but their opponents were too powerful. In the course of twenty years Portugal had founded an empire that had its forts and trading-marts from the coast of Arabia to Malaysia. Zanzibar, Aden, Oman, Goa, Calicut, and Madras were all Portuguese stations, fortified and secured. In the Malay peninsula was founded the colony of Malacca. It retained its importance and power until in the last century, when it dwindled before the competition of Singapore.

The work of building up this great domain was largely that of one man, the intrepid Albuquerque. Think what his task was! He was thousands of miles from home and supplies, he had only such forces and munitions as he could bring with him in his little ships, and opposed to him were millions of inhabitants and a multitude of Mohammedan princes. Yet this great captain built up an Indian empire. Portugal at one bound became the greatest trading and colonizing power in the world. Her sources of wealth appeared fabulous, and, like Venice, she made every effort to secure her monopoly. The fleets of other nations were warned that they could not make use of the Cape of Good Hope route, on penalty of being captured or destroyed.

Reaching India by Sailing West.The Earth as a Sphere.—Meanwhile, just as Portugal was carrying to completion her project of reaching India by sailing east, Europe was electrified by the supposed successful attempt of reaching India by sailing directly west, across the Atlantic. This was the plan daringly attempted in 1492 by Christopher Columbus. Columbus was an Italian sailor and cosmographer of Genoa. The idea of sailing west to India did not originate with him, but his is the immortal glory of having persistently sought the means and put the idea into execution.
