But it is doubtful whether the idea of a national ensign originated in the maritime states. The first of the Italian cities to adopt a democratic form of government was Milan, where the people, under the leadership of their Archbishop, Aribert, successfully resisted the Emperor Conrad himself. In the course of the struggle, about the year 1038, Aribert introduced as a rallying point for his people in battle a movable standard, which is described by Arnulf as a lofty beam, like the mast of a ship, fixed on a strong wagon and bearing a golden apple at the summit, from which hung two white streamers (pendentibus duobus candissimi veli limbis). Midway on this pole was placed a crucifix, to which the eyes of the citizens might turn for comfort whatever the fortunes of the fight might be. This device was afterwards adopted by most of the city-states of Italy, and under the name of carroccio (chariot) will be met with frequently in their annals. In its later development an altar was placed at the base of the mast, while the wagon, drawn by white oxen, was hung with scarlet cloth and the city flag floated at the masthead.
Among the cities that adopted this form of standard were Cremona, where it was named "Berta," Brescia, Bologna, Florence and Parma. In the case of Parma, where the standard was called "Blancardo," an interesting instance of its symbolic importance other than in battle is recorded. In 1303, when Ghiberto of Correggio obtained possession of that city, he got himself confirmed as "lord, defender, and protector of that city, and was invested by the resignation into his hands of the standard of the Virgin and the flag of the Carroccio[59]."
This investiture by flag, already illustrated in the case of Charlemagne and Rupen, is worthy of two further illustrations. In 1329 Padua recognised Alberto della Scala as its lord by presenting him with the flag of the people (vexillum populi) in public assembly, and in 1406 acknowledged its overthrow by Venice by presenting the same symbol to the Doge Steno. In this year also Verona acknowledged its defeat by surrendering to the Venetians its communal flag (a white cross on red ground) and its vexillum populi (a golden cross on azure field).
As a final example of the use of flags in the mediaeval Italian republics we may take the case of Florence. In October, 1250, in the course of a sanguinary struggle between the Guelphs and Ghibellines, the popular party (then Guelph)
marched in military array to San Lorenzo, and there elected thirty leaders, annulled a portion of the functions of the Podestà, and appointed as guardian of the new government a captain of the people, Messer Uberto da Lucca, with whom were to be associated twelve elders (two for each division of the town) as councillors for him and advisers of the people.
The captain was to be a foreigner; but the elders were to be Florentines.
The fighting population was divided into twenty companies each with a standard of its own, and the force thus created was intended, under the leadership of the captain, to defend the liberties of the people within the town. Outside Florence the army was still to be commanded by the Podestà. The captain's standard showed a red cross on a white field: to this day the ensign of the town of Florence. The nobles and the powerful burghers (popolani) formed a separate force—that of the knights. Each sesto or division of the town had a separate ensign for its troop of cavalry, and these banners, with many others, were given solemnly by the Podestà on every Whitsunday.
The contado was also divided into companies under respective standards, and when called into the town, fell naturally into line with the city bands.
All these changes were intended to check the power of the Ghibellines, who soon came to be so hated by the majority of Florentines that a common banner even was felt as an intolerable evil, and the Guelph party adopted a red lily on a white field, leaving the white lily on a red field (the old arms of the commune) to the opposite faction[60].
Here again we have two national flags as at Genoa, but with a marked difference in the underlying meaning. One, the red flag with white lily, the ensign of the aristocratic classes: the other, the red cross, that of the common people.
