By the mid-19th century, the Ottomans had occupied Crete for more than two centuries, despite frequent bloody uprisings by Cretan rebels.
While the Cretans were rising against the Ottoman occupation during the War of Greek Independence, the London Protocol of 1830 dictated that the island could not be a part of the new Greek state.

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.
The Ottoman authorities in Crete were reluctant to implement any reform.
Before the majority of Muslim conversions (the majority of the former Christians had converted to Islam and then recanted), the Empire tried to recant on liberty of conscience.

The institution of new taxes and a curfew also added to the discontent.
In April 1858, 5,000 Cretans met at Boutsounaria.
Finally an imperial decree on July 7, 1858 guaranteed them privileges in religious, judicial and financial matters.
One of the major motivations of the revolt of 1866 was the breach of the Hatti-Houmayoun.

A second cause of the insurrection of 1866 was the interference of Isma'il Pasha in an internal quarrel about the organization of the Cretan monasteries.
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.
Isma'il Pasha intervened and designated several people to decide the subject and annulled the election of "undesirable" members, imprisoning the members of the committee that had been charged with going to Constantinople for presenting the subject to the Patriarch.
This intervention provoked violent reactions from the Christian population of Crete.

In the spring of 1866, meetings took place in several villages.
On May 14, an assembly was held in the Aghia Kyriaki monastery in Boutsounaria near Chania.
They sent a petition to the Sultan and the consuls of the big powers in Chania.
At the time of the first meetings of the revolutionary committees, the representatives were elected by province and the representative of the Rethymno region was the hegumen of Arkadi, Gabriel Marinakis.

At the announcement of these nominations Isma'il Pasha sent a message to the hegumen via the Bishop of Rethymno, Kallinikos Nikoletakis.
The letter demanded that the hegumen dismiss the revolutionary assembly or the monastery would be destroyed by Ottoman troops.
In the month of July 1866, Isma'il Pasha sent his army to capture the insurgents, but the members of the committee fled before his troops arrived.
The Turks left again after destroying icons and other sacred objects that they found in the monastery.

In September, Isma'il Pasha sent the hegumen a new threat of destroying the monastery if the assembly did not yield.
The assembly decided to implement a system of defense for the monastery.
On September 24, Panos Koronaios arrived in Crete and landed at Bali.
He marched to Arkadi, where he was made commander-in-chief of the revolt for the Rethymno region.
A career military man, Koronaios believed that the monastery was not defensible.
The hegumen and the monks disagreed and Koronaios conceded to them, but advised the destruction of the stables so that they could not be used by the Turks.
This plan was ignored.
After having named Ioannis Dimakopoulos to the post of commander of the garrison of the monastery, Koronaios left.
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 Turks.
By 7 November 1866, the monastery sheltered 964 people: 325 men, of which 259 were armed, the rest women and children.
