A rebellion, which threatened a major outbreak, was checked (in 1643) by father Fray Cristobal Enriquez. In the district of Malolos in the province of Bulacan, an Indian named Don Pedro Ladia, a native of Borney, continued to promote sedition; he declared that he had the right to be the king of the provinces of Tagalos, saying that he was a descendant of Raja Matanda, the little king found by the Spanish in Manila in the year 1571.
By these and other pretensions, aided by wine—the chief adviser in matters of policy and war, to those natives—and by the demonic consultations which were always seen on these occasions, he kept the many villages of that district. But the wise method of father Fray Cristobal Enriquez prevented all these misfortunes that threatened us, by giving a plan for the capture of Don Pedro Ladia -who had already styled himself "king of Tagalogs;" he was sent to Manila, where he paid with his life for his foolish assumption. And so this revolt, without even the faintest foundation, was completely silenced.
According to Isabelo de los Reyes y Florentino's article in "Los Regulos de Manila", pages 87-111 of Articulos varios (Manila, 1887), recognized by Dr. Jose Rizal was Raja Mura to Raja Soliman, and said he was called Raja Mura or Rahang Mura (young Raja) as opposed to Raja Matanda or Rahang Matanda (old Raja). In the said article, De los Reyes sought to identify Raja Mura or Raja Soliman with Raxobago of San Agustin and declared that Raja Matanda and Lacandola were the same.
