Open riot ensued, and the priests marched to the Palace, amidst hideous clamourings, collecting the mob and citizens on the way. It was one of the most revolting scenes and remarkable events in Philippine history. Priests of the Sacred Orders of Saint Francis, Saint Dominic, and Saint Augustine joined the Recoletos in shouting "Viva la Iglesia," "Viva nuestro Rey Don Felipe Quinto." [28] The excited rabble rushed to the Palace, and the Guard having fled, they easily forced their way in. One priest who impudently dared to advance towards the Governor, was promptly ordered by him to stand back. The Governor, seeing himself encircled by an armed mob of laymen and servants of Christ clamouring for his downfall, pulled the trigger of his gun, but the flint failed to strike fire. Then the crowd took courage and attacked him, whilst he defended himself bravely with a bayonet, until he was overwhelmed by numbers. From the Palace he was dragged to the common jail, and stabbed and maltreated on the way. His son, hearing of this outrage, arrived on horseback, but was run through by one of the rebels, and fell to the ground. He got up and tried to cut his way through the infuriated rioters, but was soon surrounded and killed, and his body horribly mutilated.
The populace, urged by the clerical party, now fought for the liberty of the Archbishop. The prison doors were broken open, and the Archbishop was amongst the number of offenders liberated. The prelate came in triumph to the Palace, and assumed the Government in October, 1719. The mob, during their excesses, tore down the Royal Standard, and maltreated those whom they met of the unfortunate Governor's faithful friends. A mock inquiry into the circumstances of the riot was made in Manila in apparent judicial form. Another investigation was instituted in Mexico, which led to several of the minor actors in this sad drama being made the scapegoat victims of the more exalted criminals. The Archbishop held the Government for nine years, and was then transferred to the Mexican Bishopric of Mechoacan.
Pedro Manuel de Arandia (1754-59) is said to have expired of melancholy, consequent, in a measure, on his futile endeavours to govern at peace with the friars, who always secured the favour of the King.
