The first extension of borders of Greek state came in more from thirty years afterwards the nomination of his independence. With the treaty that was signed in 17/29 March 1864 between three Forces, England, France and Russia and in the Greek kingdom the Eptanisa passed finally in the Greek sovereignty in 21 May. This development came as crowing of a line of consultations and diplomatic negotiations that determined heavy terms on Greece, which was excluded from most diplomatic meetings. This treaty established the neutrality of Corfu, and that is the cause of demolished part of fortress of city and Paxon. The Greek state accepts all the obligations to foreigner governments, companies and private individuals, which are influenced from conventions that had been contracted with Ionian state or with the Protector Force, the Great Britain. This regulation concerned the public debt of Ionian Islands, commercial and shipping privileges of foreigners and mainly the editorial right of Ionian Bank. The Greek state undertook also to overwhelm compensations and pensions in the English employees that would lose their place with the Union. The Orthodox Church is recognized as prevailed, but is declared at the same time the religious freedom for all the doctrines and maintained the privileges of Catholic Church. Great Britain resigns from the protection of Ionian Islands and with France and Russia extends the guarantees that concerned Greece in the Ionian Islands too. In 23 September/5 October the Ionian Parliament materialised the aim of his convocation deciding festively the Union with Greece in "one and indivisible state under the constitutional sceptre of Giorgio the first". This development caused some bitterness in a portion of people that had fought for a subversive and revolutionary Union with independent and democratic Greece.
