Mexican War of Independence
Iturbide's assignment to the Oaxaca expedition coincided with a successful military coup in Spain against the monarchy of Ferdinand VII. The coup leaders, part of an expeditionary force assembled to suppress the independence movements in the Americas, had turned against the monarchy. They compelled the reluctant Ferdinand to reinstate the liberal Spanish Constitution of 1812 that created a constitutional monarchy. When news of the liberal charter reached Mexico, Iturbide perceived it both as a threat to the status quo and a catalyst to rouse the criollos to gain control of Mexico. Independence was achieved when conservative Royalist forces in the colonies chose to rise up against the liberal regime in Spain; it was an about-face compared to their previous opposition to the peasant insurgency. After an initial clash with Guerrero's forces, Iturbide assumed command of the royal army. At Iguala, he allied his formerly royalist force with Guerrero’s radical insurgents to discuss the renewed struggle for independence.
India–Mexico relations
In 1947, Mexico became the first Latin American nation to recognize the independence of India from the United Kingdom. On first 1 August 1950, both nations established diplomatic relations and on the following year, Mexico opened an embassy in Delhi. To show the importance of the new relations between the two nations, the first Mexican ambassador to India was former Mexican President Emilio Portes Gil. In 1962, Nobel Prize laureate Octavio Paz was named ambassador to India.
