What is aristokrasya o oligarkiya?

Aristokrasya (aristocracy) refers to a form of government or social system in which power is held by a small, privileged ruling class, often based on noble lineage or wealth. Oligarkiya (oligarchy), on the other hand, is a system where a few individuals or groups hold significant power, typically due to wealth, military control, or political influence. While both systems concentrate power in the hands of a few, aristocracy is often linked to hereditary privilege, whereas oligarchy can include various forms of elite power without a specific focus on nobility.
