Guided by the advice of the Great Powers, the Sultan confirmed the election of Prince Kusa, but by means of two Firmans, a diplomatic sleight of hand, by which the fait accompli of the irregular union remained undisturbed, albeit unrecognised. Formal sanction to the union was not conceded by the Sublime Porte until 1861. Prince Kusa, whose private life was by no means above reproach, endeavoured to fulfil in public the patriotic ambition of furthering his people's progress. But Roumania at that period was not prepared for the purely parliamentary form of government it had assumed, and the well-meant reforms initiated by the Prince and the Chamber achieved no immediate result. Prince Kusa, therefore, felt himself compelled to abolish the Election Laws by a coup d'état, and to frame a new one, which obtained the sanction of the Sublime Porte, and eventually the approval of the majority of the nation.
The increased liberty of action gained by the Prince was utilised to the full in formulating a series of necessary and excellent reforms; he failed, however, to place the budget on a satisfactory footing, and the finances remained in the same unfavourable condition as before, whilst several of his measures were directly opposed to the interests of certain factions and classes of the population. In addition to these difficulties, scandals arose which were based only too firmly upon the extremely lax life which Prince Kusa led, and a conspiracy was formed for his overthrow which found a ready support throughout the land. The Palace at Bucharest was surprised on the night of February 22, 1866, by a band of armed men, who forced the Prince to abdicate and quit the country. This accomplished, the leaders of the various parties assembled and formed a Provisional Government under the Lieutenance Princière, or regency, which consisted of General N. Golesku, Colonel Haralambi and Lascar Catargiu.
The Chamber at once proceeded to elect a new ruler, and their first choice fell upon the Count of Flanders, the younger brother of the King of Belgium. Napoleon III., however, who was then still able to play the arbitrator in the affairs of Europe, hinted that the Count would be better advised to decline the proffered crown. The Emperor's wish was acceded to, and, although the Provisional Government for a time appeared to persist in the election of the Count of Flanders, Roumania was ultimately forced to look for a candidate whose election would not be opposed by any of the Great Powers.
The choice was difficult, if not impossible; for the Paris Conference, which had reassembled in the meantime, had decided against the union of the Principalities; and, unless Roumania could attain its object semi-officially by the favour of the Great Powers, the position was hopeless.
It was, indeed, a serious, not to say alarming, situation; for a war between Prussia and Austria for the hegemony of Germany was imminent, and threatened to lead to further complications in the East. If the election were delayed until after the outbreak of hostilities, one of the belligerent parties was certain to reject the candidate whose election the other approved, whilst Russia would take advantage of the interregnum to stir up the whole of Roumania, especially Moldavia, against the union; for anything that might tend to impede the Russian advance upon Constantinople could not fail to evoke the most lively hostility in St. Petersburg. It was, therefore, upon France and her Emperor that all the hopes of the Roumanians reposed: with Napoleon on their side everything was possible, without him nothing.
The leading Roumanian statesmen were well aware of the difficulties in the way, and eventually fixed upon Prince Charles of Hohenzollern as their candidate, for he was related to both the French and Prussian dynasties, upon whose goodwill and support he might confidently reckon. It was of the utmost importance, therefore, to move him to accept their offer at once, and to obtain the sanction of the nation by a plébiscite.
