About three hundred years before the events of Volume 1, the Republic was founded in the wake of a democratic revolution against the monarchy. The revolution was led by a woman who would later be called San Magnolia, whose martyrdom resulted in her becoming the namesake of the Republic.
The Republic prided itself on being a nation of diverse cultures accepting to all different races. While the open immigration policies meant many different ethnic groups, collectively called the Colorata, settled within its borders, the Republic's population remained majority Alba. Immigrants also seemed to have some difficulty in upward mobility in social classes as few of the Colorata lived in upper class districts of the Republic's capital even before the outbreak of war. The Colorata families that did live in these districts likely were of noble lineage, such as that of Shinei Nouzen's. The presence of long lines of nobility in the upper class three hundred years after the fall of the monarchy, even of smaller lines like that of Vladilena Milizé, may also be a hint that the class society of the country has not changed as much as the Republic would like to think.
