Final answer:
From 1450 to 1750, empires used monumental architecture to legitimize political authority, exemplified by Egypt's Great Temple at Abu Simbel and similar structures.
Step-by-step explanation:
Throughout the period from 1450 to 1750, empires utilized monumental architecture and art to legitimize their political authority. This includes the construction of temples, palaces, and monuments that both reflected the power of the ruling class and reinforced their claim to rule. For instance, the New Kingdom of Egypt constructed temples and statues such as the Great Temple at Abu Simbel to exude their power.
In the 21st century, the reinforcement of political authority through monumental architecture can still be observed, although the means and ends may have transformed. Modern governments continue to erect significant buildings—parliament houses, memorials, and museums—that symbolize national identity and the legitimacy of the state. Such buildings often become the physical embodiment of political narratives and historical continuity.
