The mutual agreement between the two countries for the economic development of Morocco had, through financial rivalries, not worked well. There was also friction over similar attempts for the development of the French Congo. In this state of affairs, the French sent a military expedition to Fez in the early summer of 1911 for the ostensible purpose of protecting the Sultan from attack by rebels and of relieving the French military mission. The Germans, backed up, indeed, by the French anti-militarist press, declared that this was a mere pretext for encroachment. Spain also took the opportunity of asserting its rights to parts of the North in accordance with its reversionary claims by the Treaty of 1904. Thereupon Germany declared that the agreements of Algeciras and of 1909 had been nullified by France and demanded compensations. The gunboat _Panther_ suddenly appeared in the port of Agadir (July 1) and the Germans began to call for their share in the partition of Morocco. Difficult negotiations were carried on between France and Germany through the summer of 1911, and at moments the two countries were on the very brink of war. The English Government backed up France. Lloyd George and Premier Asquith made public declarations to that effect. French capitalists also began calling in their funds invested in Germany and a financial crisis threatened that country. Thus brought to terms the Germans became more moderate in their demands, and it was finally possible to reach a compromise, unsatisfactory to both parties. Germany definitely gave up all political claim to Morocco and acknowledged France as paramount there. On the other hand, a territorial readjustment was made in the Congo by which Germany added to the Cameroons about two hundred and thirty thousand square kilometres of land with a million people, and the new frontiers made annoying salients into the French Congo. The treaty was signed in November, 1911, but the Pan-Germanists were angry at any concessions to France, the Colonial Minister resigned, and the Emperor, who had thrown his influence on the side of peace, lost much prestige for a while. On the other hand, the French were correspondingly dissatisfied at the losses in the Congo. The opponents of the Prime Minister, Caillaux, had often taunted him with too close a relation between his official acts and his private financial interests. They now accused him of tricky concessions to Germany in connection with the Congo adjustments. M. Caillaux denied in the Chamber that he had ever entered into any private dealings apart from the negotiations of the ministry of Foreign Affairs. However, Clemenceau asked the Foreign Minister, M. de Selves, point-blank if the French Ambassador at Berlin had not complained of interference in the diplomatic negotiations. M. de Selves refused to answer, thus implicitly giving the lie to M. Caillaux. The consequence was a cabinet crisis and the resignation of the Ministry (January, 1912).
