Why did the Mexican flag change so many times?

The Mexican flag changed multiple times throughout history due to the country's political transformations and the influence of various leaders and regimes. Initially inspired by the Aztec heritage, the flag evolved during the Wars of Independence and later under different governments, each seeking to symbolize national identity and unity. Additionally, the incorporation of new symbols and colors reflected social and military changes, as well as responses to foreign invasions and internal conflicts. These adaptations illustrate Mexico's dynamic history and the ongoing quest for a cohesive national identity.
