[2] Before the abdication of King Amadeo I of Spain, Alaminos was sent to assume the position of Governor-General of the Philippines on 24 January 1873.

[3] During his term, Alaminos fought against the Archbishop of Manila, Gregorio Melitón Martínez, keeping the conflict between the colonial government and the church ongoing.

It was during the administration of former Governor-General Carlos María de la Torre y Navacerrada when the conflict was rekindled.

In around 1870, the governor-general appointed Luis Alcalá-Zamora as Bishop of Cebu but it was not approved by Archbishop Gregorio Melitón Martínez.

[4] Alaminos was replaced by an interim governor in 1874, during the administration of President Francisco Serrano, 1st Duke of la Torre.
