The Christian Cretans had risen up together with the rest of Greece in the Greek Revolution of 1821, but despite successes in the countryside, the Ottomans held out in the four fortified towns of the northern coast (Chania, Rethymno, Irakleio and Agios Nikolaos) and the island was eventually reconquered by 1828, becoming an Egyptian province (Muhammad Ali's Egypt, though nominally a vassal of the Ottoman Empire, was a regional power in its own right).
In 1840, Crete was returned to direct Ottoman rule, followed by an unsuccessful 1841 uprising in support of Union with independent Greece.
These concessions were resented by the Cretan Muslims, though Christians pressed for more, while maintaining their ultimate aim of union with Greece.
As tensions ran high in the island, and several petitions to the Sultan went unanswered, armed bands were formed, and the uprising was officially proclaimed on 21 August 1866.
On 30 March 1856, the Treaty of Paris obligated the Sultan to apply the Hatti-Houmayoun, which guaranteed civil and religious equality to Christians and Muslims.
[3] A second cause of the insurrection of 1866 was the interference of Hekim Ismail Pasha, wāli of Crete, in an internal quarrel about the organization of the Cretan monasteries.
[4] Several laymen recommended that the goods of the monasteries come under the control of a council of elders and that they be used to create schools, but they were opposed by the bishops.
[4] One particular event caused strong reactions among the liberal circles of western Europe, the "Holocaust of Arkadi".
The event occurred in November 1866, as a large Ottoman force besieged the Arkadi Monastery, which served as the headquarters of the rebellion.
As reported by the American writer and consul William Stillman and others over the recently introduced telegraph, this event caused enormous shock in the rest of Europe and in North America and decreased the perceived legitimacy of Ottoman rule.
In the month of July 1866, Ismail Pasha sent his army to capture the insurgents, but the members of the committee fled before his troops arrived.
[9] At his departure, numerous local residents, mostly women and children, took refuge in the monastery, bringing their valuables in hopes of saving them from the Ottomans.
[10] Since the mid-October victory of Mustafa Pasha's troops at Vafes, the majority of the Ottoman army was stationed in Apokoronas and were particularly concentrated in the fortresses around the bay of Souda.
[11] From Episkopi, Mustafa sent a new letter to the revolutionary committee at Arkadi, ordering them to surrender and informing them that he would arrive at the monastery in the following days.
[12] In late 1866 Isma'il Pasha (Egypt's Khedive) sent an Egyptian military contingent to aid the Ottoman Empire in putting down the rebellion.
The contingent was made up of 16,000 infantry troops under the command of Emirliva (major-general) Ismail Shaheen Pasha and was transported by the Egyptian Navy.
On the morning of 8 November, 1866, an army of 15,000 Ottoman soldiers and 30 cannons, directed by Suleyman, arrived on the hills of the monastery while Mustafa Pasha waited in the Messi.
[13] The Cretans were relatively protected by the walls of the monastery, while the Ottomans, vulnerable to the insurgents' gunfire, suffered numerous losses.
On the side of the insurgents, a war council decided to ask for help from Panos Koronaios and other Cretan leaders in Amari.
[15] The messengers returned later in the night with the news that it was now impossible for reinforcements to arrive in time because all of the access roads had been blocked by the Ottomans.
[19] The remains of numerous Cretan Christians were collected and placed in the windmill, which was made into a reliquary in homage to the defenders of Arkadi.
The Russian consulate had to intervene to require Mustafa Pasha to keep basic hygienic conditions and provide clothing to the prisoners.
This group published a brochure on The question of the Orient and the Cretan Renaissance, contacted French politicians and organized conferences in France and in Athens.
[22] Letters written by Victor Hugo were published in the newspaper Kleio in Trieste, which contributed to the worldwide reaction.
The battle lasted two days and two nights; the convent had twelve hundred holes found in it from cannon fire; one wall crumbled, the Turks entered, the Greeks continued the fight, one hundred fifty rifles were down and out and yet the struggle continued for another six hours in the cells and the stairways, and at the end there were two thousand corpses in the courtyard.
A terrible intervention, the explosion, rescued the defeated...and this heroic monastery, that had been defended like a fortress, ended like a volcano.
More importantly, he designed an Organic Law which gave the Cretan Christians equal (in practice, because of their superior numbers, majority) control of local administration.
He thus gained the minimum of political cooperation needed to retain control of the island by early 1869 and almost all the rebel leaders had submitted to Ottoman rule though some, notably the pro-Russian Hadjimichaelis, remained in exile in Greece.
