The Appointment of Governor Ronquillo.--It was the uniform policy of the Spanish government to limit the term of office of the governor to a short period of years. This was one of the futile provisions by which Spain attempted to control both the ambition and the avarice of her colonial captains. But Don Gonzalo Ronquillo had granted to him the governorship of the Philippines for life, on the condition of his raising and equipping a force of six hundred in Spain, largely at his own expense, for the better protection and pacification of the archipelago. This Ronquillo did, bringing his expedition by way of Panama. He arrived in April, 1580, and although he died at the end of three years, his rule came at an important time. The Spanish and the Portuguese Colonies Combined.--In 1580, Philip II, conquered and annexed to Spain the kingdom of Portugal, and with Portugal came necessarily to the Spanish crown those rich eastern colonies which the valor of Da Gama and Albuquerque had won. Portugal rewon her independence in 1640, but for years Manila was the capital of a colonial empire, extending from Goa in India to Formosa. Events of Ronquillo's Rule.--Ronquillo, under orders from the crown, entered into correspondence with the captain of the Portuguese fortress on the island of Tidor, and the captain of Tidor petitioned Ronquillo for assistance in reconquering the tempting island of Ternate. Ronquillo sent south a considerable expedition, but after arriving in the Moluccas the disease of beri-beri in the Spanish camp defeated the undertaking. Ronquillo also sent a small armada to the coasts of Borneo and Malacca, where a limited amount of pepper was obtained. The few years of Ronquillo's reign were in other ways important. A colony of Spaniards was established at Oton, on the island of Panay, which was given the name of Arévalo (Iloilo). And under Ronquillo was pacified for the first time the great valley of the Cagayan. At the mouth of the river a Japanese adventurer, Tayfusa, or Tayzufu, had established himself and was attempting the subjugation of this important part of northern Luzon. Ronquillo sent against him Captain Carreon, who expelled the intruder and established on the present site of Lao-lo the city of Nueva Segovia. Two friars accompanied this expedition and the occupation of this valley by the Spaniards was made permanent.
