In 1845 an attempt to restore the federal union failed; in 1851 Carrera defeated the Federalist forces of Honduras and Salvador at La Arada near Chiquimula, and was recognized as the pacificator of the republic. In 1851 a new constitution was promulgated, and Carrera was appointed president till 1856, a dignity which was in 18J4 bestowed upon him for life.
Then, greeted with the title of "The Great Pacificator" as a reward for his success, he retired temporarily to private life, with a larger stock of popularity than he had ever had before.
The first edition of the Systeme du monde was inscribed to the Council of Five Hundred; to the third volume of the Mecanique celeste (1802) was prefixed the declaration that, of all the truths contained in the work, that most precious to the author was the expression of his gratitude and devotion towards the "pacificator of Europe"; upon which noteworthy protestation the suppression in the editions of the Theorie des probabilites subsequent to the restoration, of the original dedication to the emperor formed a fitting commentary.
To the Protectionists this was "like a crash of thunder in winter"; but it was received with such favour by the country generally, that its author was hailed as "The Great Pacificator," as he had been thirteen years before at the time of the Missouri Compromise (see below).
