sea-power had left the archipelago at the mercy of the Greek war-brigs; piracy flourished; and it became essential in the interests of the commerce of all nations to make some power responsible for the policing of the narrow seas. On the 25th of March 1823 accordingly, Canning announced the recognition by Great Britain of the belligerent character of the Greeks.

This roused the emperor Alexander to action, since it seemed as though Great Britain was aiming at ousting Russian influence in the Levant. He suggested a joint intervention of the powers; but the conference, which met at St Petersburg in April 1824, came to nothing, since Turkey and the Greeks alike refused to be bound by its decisions, and Canning would not hear of coercion being applied to either. The sole outcome of the conference was the offer in March 1825 of the joint mediation of Austria and Russia, which the Porte rejected.

Meanwhile Mahmud, realizing the impossibility of crushing the Greek revolt unaided, had bent his pride to ask the help of Mehemet Ali, who was to receive as his reward Crete, the Morea and the pashaliks of Syria and Damascus. The Egyptian fleet and disciplined army were now thrown into the scale; and from the moment when Ibrahim Pasha landed at Modon (Feb. 24, 1825), the fate of the Greeks seemed sealed. The Morea was quickly overrun; in April 1826 Missolonghi fell, after a heroic defence; in June 1827 Athens was once more in the hands of the Turks. Crowds of Greek captives were being sent as slaves to Cairo; and, should the powers not intervene, there was every prospect of Greece being depopulated and colonized with Mussulman negroes and fellahin.

At the close of 1825 an isolated intervention of Russia had seemed probable. A great army was assembled in the south of Russia, and the emperor Alexander had gone to place himself at its head when he died (Dec 22, 1825). It was to prevent such an intervention that Canning seized the opportunity of the accession of Nicholas I. to send the duke of Wellington to St Petersburg in order to concert joint measures. The result was the protocol of St Petersburg of the 4th of April 1826, by which Great Britain was empowered to offer to the Ottoman government a settlement of the Greek question based on the establishment of Greece as a vassal and tributary state. Should the Porte refuse, the two powers were to take the earliest opportunity, either separately or in common, of establishing a reconciliation on the basis of the protocol.

Russia, meanwhile, had seized the occasion to send to Constantinople an ultimatum demanding satisfaction for her own particular grievances; the Porte resented the intrusion of new Convention of Akkerman. demands before the others had been dealt with, and hurried on preparations for war. The reform of the army, however, involved the destruction of the Janissaries (q.v.), and though their massacre on the 15th of June left the sultan free to carry out his views with regard to the army, it left him too weak to resist the Russian demands. On the 7th of October, accordingly, these were conceded by the Convention of Akkerman. Its terms were: the confirmation of the Treaty of Bucharest and the opening of the navigation of the Black Sea to the Russian flag; a stipulation that the hospodars of Walachia and Moldavia should be elected by the boyars for seven years, their election being confirmed by the Porte which, however, had no power to dismiss them without the concurrence of the Russian ambassador at Constantinople; finally, Servia's autonomy was recognized, and, save in the fortresses, no Mussulman might reside there.

The Greek question was however, not yet settled. Months passed without any action being taken under the protocol Agreement of the Powers as to Greece. of the 4th of April; and Russia suspected Great Britain of merely using the protocol to prevent her own isolated intervention. The situation was however materially altered by the end of August 1826; for the Greeks, driven to desperation, had formally invited the mediation of England, thereby removing Canning's objection to an unasked intervention. He now invited the co-operation of Russia in representations to the Porte on the basis of the protocol, and, in the event of its refusal to come to terms, suggested certain measures of coercion. The tsar consented, and proposed that the coercion should take the form of a pacific blockade of the Morea, so as to force Ibrahim, by cutting off his supplies, to evacuate the country. To this Great Britain agreed in principle; for Canning clearly saw the need for yielding on the question of a joint intervention, if the isolated intervention of Russia were to be prevented. In the conference of the five powers of the Grand Alliance opened at London in the early summer of 1827, however, a divergence of views at once became apparent. Austria and Prussia protested against any coercion of the Porte “to serve revolutionary ends” and, failing to carry their views, withdrew from the conference. France thereupon proposed to convert the protocol of the 4th of April into a treaty; Russia and Great Britain agreed; and on the 6th of July the Treaty of London was signed by the three powers.

By the patent articles of the treaty the powers agreed to secure the autonomy of Greece under the suzerainty of the sultan, but without any breach of friendly relations with Turkey. By additional secret articles it was agreed that, in the event of the Porte not accepting the offered mediation, consuls should be established in Greece, and an armistice proposed to both belligerents and enforced by all the means that should “suggest themselves to the prudence” of the high contracting powers. In general it was allowed that these means should be the “pacific blockade” proposed by the tsar. Instructions to this effect were sent to the admirals commanding in the Levant.

The armistice, accepted by the Greeks, was refused by Ibrahim, pending instructions from Constantinople, though he Navarino. consented to keep his ships in the harbour of Navarino. The Greeks, having put themselves in the right with the powers, were free to continue the war; and the destruction of a Turkish flotilla off Salona on the 23rd of September followed. Ibrahim, taking this as a breach of the convention, set sail from Navarino northwards, but was turned back by Sir Edward Codrington, the British admiral. Then, the Russian and French squadrons having joined, it was determined to put further pressure on the Egyptian commander, and the allied fleets, on the morning of the 20th of October, stood into the bay of Navarino. A chance scuffle led to a battle, and by the evening the Turkish and Egyptian fleets had ceased to exist (see Navarino, Battle of).

The effect on the passionate sultan of this “unparalleled outrage on a friendly power in time of peace” is easy to imagine. In spite of the weak efforts of the British government to palliate the significance of this “untoward incident,” Turkey broke off diplomatic relations with the three powers concerned, and on the 20th of December Mahmud, giving full vent to his rage, issued a hatt-i-sherīf denouncing the cruelty and perfidy of the Christian powers, declaring the convention of Akkerman null and void, and summoning the faithful to a holy war. The struggle that followed was, however, destined once more to be a duel between Russia and Turkey. Great Britain, when Canning was no longer at the helm of state, had reverted to the traditional policy of preserving Ottoman integrity at all costs; the invitation of the tsar to accept the logical consequences of Navarino was refused; and Russia was left to settle her account with Turkey.

The war that followed proved once more the wonderful resisting power of the Turks. In spite of the confusion due War with Russia. to the destruction of the Janissaries and army reforms as yet hardly begun, it cost the tzar two hardly fought campaigns before the audacious strategy of General Diebitsch enabled him to dictate the terms of the treaty of Adrianople (Sep. 14, 1829). Meanwhile the other powers had taken advantage of the reverses of the Russian arms to discount the effect of their ultimate victory by attempting to settle the Greek question. In July 1828 France had been commissioned to oust Ibrahim from the Morea; and though by a convention, concluded on the 9th of
