The affairs of the missions will be dealt with subsequently, in a comprehensive manner, but a difficulty which arose in 1623 between the Governor, João Corrêa de Souza, and the Jesuits, may be dealt mentioned at once. In 1619, Gaspar Alvares,[482] a wealthy merchant of Luandu, placed 20,000 cruzados at the service of the Fathers, in order that they might found a seminary[483] for the education of twelve natives. Subsequently he himself became a member of the Society of Loyola, and devoted the whole of his fortune, amounting to 400,000 cruzados, to its purposes. The Governor not unnaturally objected to this sudden enrichment of a Society which had always been a thorn in the side of the government. Alvares himself escaped to S. Salvador, but the Prefect of the Jesuits and three Fathers were sent as prisoners to Lisbon, where they were at once liberated; whilst the Governor himself, who arrived soon afterwards, perhaps with the intention of justifying his hasty proceedings, was thrown into prison, and died in the _limoeiro_ in 1626. THE DUTCH IN ANGOLA. When Philip of Spain seized upon the crown of Portugal in 1580, that unfortunate country became at once involved in the troubles between Spain and the United Netherlands. No sooner had the destruction of the _Armada_, in 1588, enabled the Dutch to take the offensive on sea, than they began to compete for a share in the trade of the Portuguese possessions. The Dutch at first kept on the defensive, but in 1598 they and the Portuguese came into hostile collision near the Ilha do Principe; and all efforts to exclude these noxious heretics from sharing in the trade of the Kongo proved futile, more especially as the natives themselves preferred their Dutch visitors to the masterful Portuguese.[484] An armistice concluded in 1609 expired in 1621. The Dutch West-India Company was founded in that very year, and thenceforth the Dutch proceeded aggressively. In 1623 they burnt several _patachos_ off the mouth of the Kwanza; in 1629 a Dutch squadron cruised during three months off the coast of Benguella and captured four Portuguese merchantmen, but failed to force their way into the harbour of Luandu. In 1633 two Dutch vessels menaced S. Felippe de Benguella, but were driven off by Lopo Soares Laço, after a stout fight, on November 15th. In 1637, Bartholomeu de Vasconcellos da Cunha, the Governor’s brother, captured a Dutch man-of-war of 24 guns. At that time the coast was being regularly patrolled by Portuguese men-of-war,[485] and in 1638 the foundations of the Fort S. Miguel were laid on the Morro de S. Paulo, the original site of the city of S. Paulo.
