In 1826 John VI. died, and Isabella becoming regent, administered the government until Pedro IV. of Brazil, the brother of the deceased king, could make it convenient to visit Portugal, and assume the reigns of government. After having done so he established a constitution, providing two legislative chambers, and then abdicated in favor of his eldest daughter, Dona Maria da Gloria. Don Miguel, his brother, the chamberlains, and the magistrates swore to support the constitution. But the first, in violation of his oath of allegiance, and of his fraternal obligations, entered into a conspiracy for its overthrow. With this object in view he organized an apostolic party, and abusing the power and confidence with which he was honored, secretly filled the army, navy, and civil offices with his adherents. Having matured his plans he caused an insurrection to break out against the queen, in order to enable him to seize the royal authority under pretense of restoring public tranquillity. England, however, interfering, the revolution was checked, and the project of usurpation frustrated. But the treasonable plot was skilfully and comprehensively laid, and the zealous support which it derived from the papal machinery soon rendered it popular with the masses. As if enamored of slavery and despotism, the people began to crowd into the ranks of the apostolic party, to second its declaration in favor of Don Miguel as king, to unite in its shouts of "Long live the absolute king," "Down with the constitutions," and to denounce, abuse and assault those who refused to echo its suicidal acclamations. A few military garrisons which still withstood the popular frenzy, and adhered to the cause of constitutional government, raised the standard of revolt; and being joined by other troops, an army was organized which marched against Lisbon. It was met by the apostolic army, which greatly outnumbered it; and being defeated, the liberal junta was dissolved and Don Miguel proclaimed absolute king. In 1834 Don Miguel was defeated by Don Pedro IV., and the constitution of 1826 was re-established by the cortes. PAPAL POLITICAL INTRIGUES IN SPAIN We will conclude our history of Papal Political Intrigues, by a cursory glance at a few of its instances with regard to the government of Spain. Catholicism was introduced into Spain in 586, under the reign of Reccared I.; and from that period the governmental affairs were controlled by the political intrigues of the clergy, until 711, when the kingdom became a province of the Caliph of Bagdad.
