Don Juan of Austria, the natural son of Charles V., who had won renown throughout the world by his annihilation of the Turkish fleet at Lepanto, was appointed in his place. Before his arrival the southern and northern provinces had bound themselves together in the Pacification of Ghent (1576). Don Juan was obliged to accept the terms of the Pacification and to dismiss the Spanish troops before his authority would be recognised. William of Orange, secure in the north, determined to occupy the southern provinces, but his public profession of Calvinism and the religious intolerance of his followers prevented a combined national effort. The Catholic nobles of the Walloon provinces objected to the Protestant campaign that was being carried on in the name of liberty, and showed themselves not unwilling to come to terms with Don Juan. The latter, only too glad to meet them half-way, issued a very conciliatory decree (1577), which secured him the support of many of the Catholic party, and partly by force, partly by negotiation he succeeded in winning back much of what had been lost.
On the death of Don Juan (1578) Alexander Farnese, son of the former regent Margaret of Parma, was appointed his successor. Being something of a statesman as well as a soldier he lost no opportunity of endeavouring to break the power of the Prince of Orange. He devoted a great deal of his energies to the work of detaching the southern provinces, which still remained Catholic, from the northern, which had gone over to Calvinism. The intolerance of the Calvinists and their open violation of the religious freedom guaranteed to all parties tended to the success of his plans. During his term of office Belgium returned its allegiance to Spain, and this step put an end to the hopes entertained by the Calvinists of winning that country to their side. Meanwhile the northern provinces were entirely in the hands of William of Orange. In 1579 the five provinces Holland, Zeeland, Friesland, Geldern, and Zutphen bound themselves together by a solemn compact in the Union of Utrecht under the name of the United Provinces, and practically speaking established a Dutch republic. They agreed to make common cause in war and in peace, and appointed William of Orange as Stadtholder for life. A short time later (1581) William of Orange, notwithstanding all his proclamations regarding religious liberty, forbade the public exercise of the Catholic religion, and refused to allow the new Archbishop of Utrecht to take possession of his See. In these circumstances nothing remained for the Pope except to appoint a vicar-apostolic to take charge of the religious interests of the Catholics, who formed two-fifths of the population of Holland, but even the vicar-apostolic was soon banished from the country.
In 1584 William of Orange was assassinated, and his son Maurice was appointed to succeed him. The English Government anxious to strike a blow at Spain encouraged the Dutch to continue the war, and despatched troops to their assistance. After the defeat of the Spanish Armada the situation was much more favourable to the rebels, and at last in 1609a twelve years' truce was concluded. On the expiration of the truce the war was renewed without any very striking success on either side.
Finally in the Peace of Westphalia (1648) the independence of the Dutch republic was acknowledged by Spain. From the very beginning of the religious revolt in the Netherlands Calvinism was the sect most favoured by the people, as is evidenced by the /Confessio Belgica/ in 1562. The University of Leyden decided in its favour, as did also the Synods of Dordrecht in 1574 and 1618. The Catholic minority in Holland were treated with the greatest severity, but in spite of all the efforts to induce them to change their faith many of the districts remained completely Catholic.
The Catholic provinces, which remained true to Spain and to the Catholic Church, suffered very severely from the long-drawn-out struggle, but despite the ravages of war they were soon the centre of a great religious, literary and artistic revival. The University of Louvain, founded in 1425, developed rapidly under the generous patronage of the civil rulers. During the sixteenth century it was recognised as an important centre of learning whither scholars flocked not merely from the Low Countries but from all parts of Europe.
Throughout the Reformation struggle Louvain and Douay, the latter of which was founded in 1562 by Philip II. to assist in stemming the rising tide of Calvinism, remained staunch defenders of Catholic orthodoxy, though the unfortunate controversies waged round the doctrines of Baius and Jansenius did something to dim the glory of the university to which both belonged. The Jesuits, too, rendered invaluable service to religion and learning, particularly the men who hastened to offer their services to Father van Bolland in his famous /Acta Sanctorum/. Nor can it be forgotten that it was in these days Catholic Belgium gave to the world the great Flemish school of artists, amongst whom must be reckoned such men as Rubens, Van Dyck, and Jordaens.
