Final answer:
The oligarchs typically passed laws that favored the rich, including policies that protected the elite's property rights, reduced their tax burdens, and maintained their social status.
Step-by-step explanation:
The oligarchs, being part of an elite ruling class, often enacted laws that favored their own interests and status. They tended to pass legislation that benefitted the wealthy and maintained social hierarchies. For instance, policies that protected property rights of the elite, reduced taxes for the wealthy, and upheld the social order were common.
This can be seen throughout history, from ancient societies, such as the Roman patricians and the aristocrats in the Code of Hammurabi, to modern times where legislation sometimes favors businesses and wealthy individuals, as in the case of the Republican-led policies of the 1920s. At times, there were attempts to curb inequality and corruption, such as the publication of the Twelve Tables in Ancient Rome, but generally, oligarchs enacted laws that supported their position and wealth.
