 A large majority of Mexicans have been classified as "Mestizos", meaning in modern Mexican usage that they identify fully neither with any indigenous culture nor with a Spanish cultural heritage, but rather identify as having cultural traits incorporating elements from both indigenous and Spanish traditions.By the deliberate efforts of post-revolutionary governments the "Mestizo identity" was constructed as the base of the modern Mexican national identity, through a process of cultural synthesis referred to as "mestizaje" .Mexican politicians and reformers such as José Vasconcelos and Manuel Gamio were instrumental in building a Mexican national identity upon the concept of mestizaje.
