Confucianism is a philosophical and ethical system based on the teachings of Confucius, a Chinese philosopher and educator who lived around the 5th century BCE. Key aspects of Confucianism include:

1. Ethical Behavior: Emphasis on moral values such as benevolence, righteousness, propriety, wisdom, and faithfulness.
2. Filial Piety: Respect for elders, ancestors, and family relationships as foundational to social harmony.
3. Five Relationships: Confucianism outlines five key relationships (ruler-subject, father-son, husband-wife, elder brother-younger brother, friend-friend) that form the basis of a just society.
4. Meritocracy: Advocacy for a system where individuals are appointed to positions based on their abilities and virtues rather than birth or wealth.
5. Rituals and Etiquette: Importance placed on rituals, ceremonies, and proper conduct in social interactions.

Confucianism has had a profound influence on Chinese culture, ethics, and governance for centuries and continues to shape societal values in East Asia.
