In the latter part of his reign, Chulalongkorn and his supporters repeatedly justified the creation of a strong state and its absolutist management on grounds of the need for Siam to progress and be a significant country in the world. This formulation marks the start of one of the two recurring visions in modern Thai politics. The same idea, adapted to changing international and local contexts, would reappear over decades to come. The Chulalongkorn era had also created the key vocabulary of this theme, particularly the notion of samakkhi, unity, and its highly masculine and militaristic imagery exemplified by Chulalongkorn's equestrian statue, and Damrong's account of Thai history as a series of wars.

An opposing vision took shape in the early 20th century, in the new urban society created by colonial commerce and by the nation-state itself. Old relationships of patronage were replaced by contracts in the marketplace. People evolved new ideas on man and society by reflecting on their own status as independent merchants and professionals, and by grabbing the increasing opportunities to compare Siam to an outside world undergoing tumultuous change. The new men and women of early 20th-century Siam took up the ideas of nation, state, and progress, and recast them. They challenged the definition of the nation as those loyal to the king. They demanded that ‘progress’ be more widely shared. They redefined the purpose of the nation-state as the well-being of the nation's members.
