The idea was a wise and subtle one; but Aguinaldo's republic was merely an elaborate stage-setting, arranged for the contemplation of the people of the United States.
By June 5, 1898, the success of the insurgent arms had been such that Aguinaldo felt that he could throw down the mask.

He would still be glad of American assistance, but he felt himself strong enough to do without it.

He saw that "there can now be proclaimed before the Filipino people and the civilized nations its only aspiration, namely, the independence of this country, which proclamation should not be delayed for any ulterior object of this government" [361] and ordered that the independence of the Philippines should be proclaimed at his birthplace, Cavite Viejo, on June 12, 1898.

On that date he formally proclaimed it.

The provinces of Cavite, Bataan, Pampanga, Batangas, Bulacan, Laguna and Morong were about to fall into his hands, the Spanish troops in them being besieged, and about to surrender.
From the same place on June 18, 1898, Aguinaldo promulgated his decree for the creation and administration of municipalities.
