Carlos Lincoln was the leader of the remnants of the Moralistas in 1901, when he was brought to the Sacramento hacienda of Diego Cortez y Catalán, President of Kramer Associates on 1 August, for the Sacramento conference to plot the overthrow of the self-proclaimed Emperor of Mexico, Benito Hermión.
As Sobel later notes, by this time Hermión had all but destroyed the last vestiges of the Moralistas as an active opposition force. Nevertheless, the Moralistas had been the most visible resistance to Hermión's dictatorship for the last twenty years, and having them on his side would gain Cortez popular support for his planned coup.
At the conference, Lincoln insisted that he wanted no part in any coup that would make Cortez himself dictator in Hermión's place. Cortez insisted that he had no wish to do so, and that "neither I nor anyone else even remotely connected with the Associates will take a position in any new or provisional government established when Hermión departs. You have my word on this."
In fact, after Cortez's men maneuvered Hermión into fleeing Mexico in October, the Commandant of the Kramer Guard, Martin Cole, became the head of the new provisional government. Cole, acting on Cortez's orders, offered amnesty to all of Hermión's opponents, including the Moralistas.
Carlos Lincoln does not have an entry in Sobel's index.
Sobel's sources for Carlos Lincoln participation in the Sacramento conference are Edward Van Gelder's The Victory of Republicanism (Mexico City, 1912); and Miguel Señada's Cortez and Hermión: Bitter Friendship (Mexico City, 1968).
