The kings of Europe contemplated this portentous change with inexpressible alarm. In consternation they witnessed the uprising of the masses in France, and saw one of their brother monarchs dragged from his palace and beheaded upon the guillotine. The successful establishment of the French Republic would very probably have driven every King in Europe from his throne. England was agitated through all her countries. From the mud cabins of Ireland, from the dark and miry mines, from the thronged streets of the city, and the crowded workshops all over the kingdom, there was a clamorous cry ascending for liberty and equality. The spirit of democracy, radiating from its soul in Paris, was assailing every throne in Europe. There was no alternative for these monarchs but to crush this new power, or to perish before it. There can be no monarchist whose sympathies will not beat high with the allied kings in the fearful conflict which ensued. There can be no republican who will not pray, "God speed the Eagles of France." Both parties believed that they were fighting in self-defense. The kings were attacked by _principles_ triumphant in France, which were undermining their thrones. The French were attacked by bayonets and batteries--by combined armies invading their territories, bombarding their cities, and endeavoring by force of arms, to compel a proud nation of thirty millions of inhabitants to reinstate, at foreign dictation, the rejected Bourbons upon the throne. The allies called upon all the loyalists scattered over France to grasp their arms, to rally beneath the banner of friends coming to their rescue, and to imbrue their country in the blood of a civil war. The French, in trumpet tones, summoned the _people_ of all lands to hail the tri-colored flag, as the harbinger of their deliverance from the servitude of ages. From every city in Europe which Napoleon approached, with his conquering armies, the loyalists fled, while the republicans welcomed him with an adulation amounting almost to religious homage. And the troops of the allies were welcomed, in every city of France which they entered, with tears of gratitude from the eyes of those who longed for the restoration of the monarchy. It was a conflict between the spirit of republicanism on the one side, and of monarchical and ecclesiastical domination upon the other.
