Manoel De Silveyra Pinto De Fonseca Chaves, marquis of, and count of Amarante, a Portuguese general and statesman, born at Villa Real, died in Lisbon, March 7, 1830. He was opposed to the Portuguese liberals, and on the arrival of the duke of Angouleme in Spain in 1823, he raised the standard of revolution in Portugal in favor of Dom Miguel and absolutism. He was proclaimed a traitor, and being defeated by Gen. Riego, he retired into Spain. There he continued to carry on his intrigues, and on the death of John VI. in 1826 he returned to Lisbon. He performed a conspicuous part in the disturbances which followed, and underwent the vicissitudes of exile and return, always retreating after his numerous defeats over the Spanish frontier. To put an end to the intrigues of the Portuguese refugees with the Spanish court, the English, who were favorable to the constitutional cause in Portugal, declared that any participation in the struggle by the Spanish authorities would be regarded as a casus belli. To avoid this risk, Chaves was sent away from the frontier. Subsequently, after Dom Miguel had been installed as regent, February, 1828, Chaves returned to Portugal and assisted the usurper in seizing the crown for himself.

This accomplished, he was neglected, and soon afterward retired from court, disgusted with the ingratitude of Dom Miguel; and the latter part of his life was spent in gloom and obscurity, still more saddened by partial insanity.
