Final answer:
Tyrants were known for building marketplaces, temples, and walls to maintain power and support the economy, making the statement true.
Step-by-step explanation:
Throughout history, tyrants were known for undertaking significant building projects to both enhance their authority and provide for the economic and social needs of their subjects. Marketplaces, temples, and city walls were among the key infrastructure developments that these rulers established. Marketplaces served as commercial hubs where trade could flourish, and wealth could be accumulated and redistributed, especially in ancient societies where money as we know it today was not yet in use. Temples and palaces not only hosted religious ceremonies but also functioned as centers for the redistribution of goods collected as taxes, serving as storage and administrative centers with scribes recording transactions in written forms like cuneiform.
In the so-called "Age of Tyrants," which occurred in Greek history from approximately 650-500 BCE, tyrants seized land from aristocrats to distribute to citizens, built public works, and endeavored to promote trade. Through these actions, they garnered support from the populace in their bid to maintain power. These undertakings inevitably led to the construction of new city infrastructure, including walls and temples which housed not only religious ceremonies but important economic functions as well. This information illustrates that the statement is true: Tyrants built new marketplaces, temples, and walls.
