The national independence of Guatemala was erelong recognized by foreign powers, with which she opened diplomatic relations and made treaties.[XIII-29] The formal recognition by Spain took place in the treaty of May 29, 1863, subsequently ratified by both governments. Guatemala has endeavored to maintain friendly relations with all. With the United States they have been quite cordial. During Carrera's rule his government gave recognition to the imperial régime of Maximilian in Mexico.[XIII-30] During the South American struggle between Chile on one side, and Peru and Bolivia on the other, Guatemala maintained herself neutral. She accepted in 1881 the invitation of the United States government to be represented at a proposed American congress to be held in Washington, but which did not take place. In that same year, owing to the maltreatment of a French citizen, a difficulty arose with France, but it was amicably settled, the French flag being saluted, and a pecuniary compensation allowed by Guatemala.[XIII-31] * * * * * [Sidenote: REVOLUTION AND ROBBERY.] On the 8th of April the official journal gave to the public a decree appointing Pedro Molina, Alejandro Marure, and J. M. Urruela a committee to frame a constitution for the new republic,[XIII-32] a project of which they presented in due time; but, though conservative, the government would not adopt it.[XIII-33] The self-styled nobles were delighted with their republic, and made it appear in the official paper that the people in the departments were equally so. But a scarcity of breadstuffs, attributed by many to the contrivances of monopolists, created disturbances in some districts, alarming the government. Certain taxes were temporarily removed, and other measures were adopted to alleviate the distress.[XIII-34]
