It might have been supposed that Europe, or at least the southern portion of it, was likely to enjoy a considerable term of peace. France, under a minor and a Regent, appeared to require rest to recruit its population and finances more than any part of the Continent. The King of Spain was too imbecile to have any martial ambition; and though his wife was anxious to secure the succession to the French throne in case of the death of the infant Louis XV., yet Alberoni, the Prime Minister, was desirous to remain at peace. This able Churchman, who had risen from the lowest position, being the son of a working gardener, and had made his way to his present eminence partly by his abilities and partly by his readiness to forget the gravity of the clerical character for the pleasure of his patrons, was now zealously exerting himself to restore the condition of Spain. He was thus brought into collision with Austria and France, and eventually with this country to which at first he was well disposed. England was under engagement both to France and the Empire, which must, on the first rupture with either of those Powers and Spain, precipitate her into war. The treaty with the Emperor--as it guaranteed the retention of the Italian provinces, which Spain beheld with unappeasable jealousy, in Austrian hands--was the first thing to change the policy of Alberoni towards Britain. This change was still further accelerated by the news of the Triple Alliance, which equally guaranteed the _status quo_ of France. The Spanish Minister displayed his anger by suspending the Treaty of Commerce, and by conniving at the petty vexations practised by the Spaniards on the English merchants in Spain, and by decidedly rejecting a proposal of the King of England to bring about an accommodation between the Emperor and the Court of Spain. In this uneasy state of things Austria very unnecessarily put the match to the political train, and threw the whole of the south of Europe again into war. Don Joseph Molina, the Spanish Ambassador at Rome, being appointed Inquisitor-General at Spain, commenced his journey homewards, furnished with a passport from the Pope, and an assurance of safety from the Imperial Minister. Yet, notwithstanding this, he was perfidiously arrested by the Austrian authorities and secured in the citadel of Milan. The gross insult to Spain, and equally gross breach of faith, so exasperated the King and Queen of Spain that they would listen to nothing but war. The earnest expostulations of Alberoni, delivered in the form of a powerful memorial, were rejected, and he was compelled to abandon the cherished hopes of peaceful improvement and make the most active preparations for war.
