With regard to the Ghent Pacification, the estates, in the course of December, procured: an express opinion from the eleven professors of theology, and doctors utriusque juris of Louvain, that the treaty contained nothing which conflicted with the supremacy of the Catholic religion. The various bishops, deacons, abbots, and pastors of the Netherlands made a similar decision. An elaborate paper, drawn, up by the State-Council, at the request of the states-general, declared that there was nothing in the Pacification derogatory to the supreme authority of his Majesty. Thus fortified; with opinions which, it must be confessed, were rather dogmatically than argumentatively drawn up, and which it would have been difficult very logically to, defend, the states looked forward confidently to the eventual acceptance by Don John of the terms proposed. In the meantime, while there was still an indefinite pause in the negotiations, a remarkable measure came to aid the efficacy of the Ghent Pacification.

Early in January, 1577, the celebrated "Union of Brussels" was formed. This important agreement was originally signed by eight leading personages, the Abbot of Saint Gertrude, the Counts Lalain and Bossu, and the Seigneur de Champagny being among the number. Its tenor was to engage its signers to compass the immediate expulsion of the Spaniards and the execution of the Ghent Pacification, to maintain the Catholic religion and the King's authority, and to defend the fatherland and all its constitutions. Its motive was to generalize the position assumed by the Ghent treaty. The new act was to be signed, not by a few special deputies alone, like a diplomatic convention, but by all the leading individuals of all the provinces, in order to exhibit to Don John such an array of united strength that he would find himself forced to submit to the demands of the estates. The tenor, motive, and effect were all as had been proposed and foreseen. The agreement to expel the Spaniards, under the Catholic and loyal manifestations indicated, passed from hand to hand through all the provinces. It soon received the signature and support of all the respectability, wealth, and intelligence of the whole country. Nobles, ecclesiastics, citizens, hastened to give to it their adhesion. The states-general had sent it, by solemn resolution, to every province, in order that every man might be forced to range himself either upon the side of the fatherland or of despotism. Two copies of the signatures procured in each province were ordered, of which one was to be deposited in its archives, and the other forwarded to Brussels. In a short time, every province, with the single exception of Luxemburg, had loaded the document with signatures. This was a great step in advance. The Ghent Pacification, which was in the nature of a treaty between the Prince and the estates of Holland and Zealand on the one side, and a certain number of provinces on the other, had only been signed by the envoys of the contracting parties. Though received with deserved and universal acclamation, it had not the authority of a popular document. This, however, was the character studiously impressed upon the "Brussels Union." The people, subdivided according to the various grades of their social hierarchy, had been solemnly summoned to council, and had deliberately recorded their conviction. No restraint had been put upon their freedom of action, and there was hardly a difference of opinion as to the necessity of the measure.

A rapid revolution in Friesland, Groningen, and the dependencies, had recently restored that important country to the national party. The Portuguese De Billy had been deprived of his authority as King's stadholder, and Count Hoogstraaten's brother, Baron de Ville, afterwards as Count Renneberg infamous for his, treason to the cause of liberty, had been appointed by the estates in his room. In all this district the "Union of Brussels" was eagerly signed by men of every degree. Holland and Zealand, no less than the Catholic provinces of the south willingly accepted the compromise which was thus laid down, and which was thought to be not only an additional security for the past, not only a pillar more for the maintenance of the Ghent Pacification, but also a sure precursor of a closer union in the future. The Union of Brussels became, in fact, the stepping-stone to the "Union of Utrecht," itself the foundation-stone of a republic destined to endure more than two centuries. On the other hand, this early union held the seed, of its own destruction within itself. It was not surprising, however, that a strong declaration in favor of the Catholic religion should be contained in a document intended for circulation through all the provinces. The object was to unite as large a force, and to make as striking a demonstration before the eyes of the Governor General as was practicable under the circumstances. The immediate purpose was answered, temporary union was formed, but it was impossible that a permanent crystallization should take place where so strong a dissolvent as the Catholic clause had been admitted. In the sequel, therefore, the union fell asunder precisely at this fatal flaw. The next union was that which definitely separated the provinces into Protestant, and Catholic, into self-governing republics, and the dependencies of a distant despotism. The immediate effect, however, of the "Brussels Union" was to rally all lovers of the fatherland and haters of a foreign tyranny upon one vital point—the expulsion of the stranger from the land. The foot of the Spanish soldier should no longer profane their soil. All men were forced to pronounce themselves boldly and unequivocally, in order that the patriots might stand shoulder to shoulder, and the traitors be held up to infamy. This measure was in strict accordance with the advice given more than once by the Prince of Orange, and was almost in literal fulfilment of the Compromise, which he had sketched before the arrival of Don John.

The deliberations were soon resumed with the new Governor, the scene being shifted from Luxemburg to Huy. Hither came a fresh deputation from the states-general—many signers of the Brussels Union among them—and were received by Don John with stately courtesy: They had, however, come, determined to carry matters with a high and firm hand, being no longer disposed to brook his imperious demeanour, nor to tolerate his dilatory policy. It is not surprising, therefore, that the courtesy soon changed to bitterness, and that attack and recrimination usurped the place of the dignified but empty formalities which had characterized the interviews at Luxemburg.

The envoys, particularly Sweveghem and Champagny, made no concealment of their sentiments towards the Spanish soldiery and the Spanish nation, and used a freedom of tone and language which the petulant soldier had not been accustomed to hear. He complained, at the outset, that the Netherlanders seemed new-born—that instead of bending the knee, they seemed disposed to grasp the sceptre. Insolence had taken the place of pliancy, and the former slave now applied the chain and whip to his master. With such exacerbation of temper at the commencement of negotiations, their progress was of necessity stormy and slow.

The envoys now addressed three concise questions to the Governor. Was he satisfied that the Ghent Pacification contained nothing conflicting with the Roman religion and the King's authority? If so, was he willing to approve that treaty in all its articles? Was he ready to dismiss his troops at once, and by land, the sea voyage being liable to too many objections?

Don John answered these three questions—which, in reality, were but three forms of a single question—upon the same day, the 24th of January. His reply was as complex as the demand had been simple. It consisted of a proposal in six articles, and a requisition in twenty-one, making in all twenty-seven articles. Substantially he proposed to dismiss the foreign troops—to effect a general pacification of the Netherlands—to govern on the basis of the administration in his imperial father's reign—to arrange affairs in and with regard to the assembly-general as the King should judge to be fitting—to forgive and forget past offences—and to release all prisoners. On the other hand he required the estates to pay the troops before their departure, and to provide ships enough to transport them, as the Spaniards did not choose to go by land, and as the deputies, at Luxemburg had consented to their removal by sea. Furthermore, he demanded that the states should dismiss their own troops. He required ecclesiastical authority to prove the Ghent Pacification not prejudicial to the Catholic religion; legal authority that it was not detrimental to his Majesty's supremacy; and an oath from the states-general to uphold both points inviolably, and to provide for their maintenance in Holland and Zealand. He claimed the right to employ about his person soldiers and civil functionaries of any nation he might choose, and he exacted from the states a promise to prevent the Prince of Orange from removing his son, Count van Buren, forcibly or fraudulently, from his domicile in Spain.

The deputies were naturally indignant at this elaborate trifling. They had, in reality, asked him but one question, and that a simple one—Would he maintain the treaty of Ghent? Here were twenty-seven articles in reply, and yet no answer to that question. They sat up all night, preparing a violent protocol, by which the Governor's claims were to be utterly demolished. Early in the morning, they waited upon his Highness, presented the document, and at the same time asked him plainly, by word of mouth, did he or did he not intend to uphold the treaty. Thus pressed into a corner in presence of the deputies, the members of the State Council who were in attendance from Brussels, and the envoys whom the Emperor had recently sent to assist at these deliberations, the Governor answered, No. He would not and could not maintain the treaty, because the Spanish troops were in that instrument denounced as rebels, because he would not consent to the release of Count Van Buren—and on account of various other reasons not then specified. Hereupon ensued a fierce debate, and all day long the altercation lasted, without a result being reached. At ten o'clock in the evening, the deputies having previously retired for a brief interval, returned with a protest that they were not to be held responsible for the termination of the proceedings, and that they washed their hands of the bloodshed which might follow the rupture. Upon reading this document; Don John fell into a blazing passion. He vehemently denounced the deputies as traitors. He swore that men who came to him thus prepared with ready-made protests in their pockets, were rebels from the commencement, and had never intended any agreement with him. His language and gestures expressed unbounded fury. He was weary of their ways, he said. They had better look to themselves, for the King would never leave their rebellion unpunished. He was ready to draw the sword at once—not his own, but his Majesty's, and they might be sure that the war which they were thus provoking, should be the fiercest ever, waged. More abusive language in this strain was uttered, but it was not heard with lamb-like submission. The day had gone by when the deputies of the states-general were wont to quail before the wrath of vicarious royalty. The fiery words of Don John were not oil to troubled water, but a match to a mine. The passions of the deputies exploded in their turn, and from hot words they had nearly come to hard blows. One of the deputies replied with so much boldness and vehemence that the Governor, seizing a heavy silver bell which stood on the table, was about to hurl it at the offender's head, when an energetic and providential interference on the part of the imperial envoys, prevented the unseemly catastrophe.

The day thus unprofitably spent, had now come to its close, and the deputies left the presence of Don John with tempers as inflamed as his own. They were, therefore, somewhat surprised at being awakened in their beds, after midnight, by a certain Father Trigoso, who came to them with a conciliatory message from the Governor. While they were still rubbing their eyes with sleep and astonishment, the Duke of Aerschot, the Bishop of Liege, and several councillors of state, entered the room. These personages brought the news that Don John had at last consented to maintain the Pacification of Ghent, as would appear by a note written in his own hand, which was then delivered. The billet was eagerly read, but unfortunately did not fulfil the anticipations which had been excited. "I agree," said Don John, "to approve the peace made between the states and the Prince of Orange, on condition that nothing therein may seem detrimental to the authority of his Majesty and the supremacy of the Catholic religion, and also with reservation of the points mentioned in my last communication."

Men who had gone to bed in a high state of indignation were not likely to wake in much better humour, when suddenly aroused in their first nap, to listen to such a message as this. It seemed only one piece of trifling the more. The deputies had offered satisfactory opinions of divines and jurisconsults, as to the two points specified which concerned the Ghent treaty. It was natural, therefore, that this vague condition concerning them, the determination of which was for the Governor's breast alone, should be instantly rejected, and that the envoys should return to their disturbed slumbers with an increase of ill-humour.
