Events abroad made a rupture easy. In spite of the provocations offered to him by the French Assembly, Leopold had clung steadily to peace. His sagacity saw that the one chance for the Monarchy in France lay in the desire of the Constitutional party to re-establish order. He was determined to strengthen their hands, if he could, and for that purpose to limit the interference of the Powers to joint diplomatic pressure in their behalf. But early in March, 1792, Leopold suddenly died. His heir Francis, unrestrained by his father's tact and moderation, assumed a different tone and showed less patience. The chances of any effective pressure from the Powers declined, as the prospect of war rose on the horizon. Francis' language was sufficiently sharp to give the Assembly the pretext which it longed for, and on the 20th April, Louis, amid general enthusiasm, came down to the Assembly and declared war against Austria. The effects of that momentous step no comment can exaggerate. It ruined the best hopes of the Revolution, and prepared the way for a military despotism in the future. All who hesitated, all who felt that mistakes had been committed but who still hoped that they might be repaired, all who believed that the Revolution might yet vindicate itself by combining liberty with order, saw themselves forced to choose, no longer between order and disorder, but between the old system and the new, between the ancient Monarchy and freedom, between the cause of their country and the cause of the invaders. Had there been no war with Europe, the astonishing episode of the Jacobin triumph, the worst excesses of the later Revolution, and all the crimes and glories of the Terror, could never have taken place in France.
