Mexican flag

Green: Represents Independence - the struggle for freedom from Spanish colonial rule and the establishment of an independent nation. White: Represents Religion - the preservation of one national religion and the Catholic faith that united the Mexican people. Red: Represents Union - the unity of all Mexican people coming together as one nation, regardless of their backgrounds or previous allegiances.

The flag's design dates back to the War of Independence with Spain (1810–1821). During this period, several different Mexican groups were fighting separately for the creation of a new nation. When these groups finally came to an agreement, they formed the Army of the Three Guarantees and agreed upon three key principles: the establishment of an independent monarchy, the preservation of one national religion, and the union of all Mexican people. Each color on the flag represents one of these three guarantees that formed the foundation of the new Mexican nation.

Three equal vertical bands arranged from left to right: Green band (left), White band (center), Red band (right). The national emblem is positioned in the center of the white band, featuring an eagle devouring a snake while perched on a cactus. The design follows a tricolor vertical stripe pattern with the central emblem serving as the focal point and symbol of Mexican national identity.

Standard flag protocol applies for the Mexican flag display. The flag should be treated with respect and dignity at all times. When displayed horizontally, the green band should be on the left side (hoist side), with the white band in the center containing the national emblem, and the red band on the right. The flag should be raised briskly and lowered ceremoniously. During national ceremonies and official events, proper respect should be shown to the flag as a symbol of Mexican sovereignty and national unity.
