The fundamental principles of Buddhism, such as the Four Noble Truths and the Eightfold Path, do not address the issue of polygamy or monogamy.
However, the general ethical principles of Buddhism, such as non-harming and compassion, would suggest that having multiple wives could potentially cause harm and suffering to the wives and any children involved. Additionally, the Buddha’s monastic code, which forms the foundation of the Vinaya Pitaka (one of the three main collections of scriptures in Buddhism), prohibits sexual relationships and encourages celibacy for monks and nuns.
In practice, the cultural and societal norms of the country or region where Buddhism is practiced may influence how marriage and relationships are viewed and practiced.
In some countries, polygamy is not legally allowed; in others, it is permitted under certain circumstances.
It is important to note that cultural or societal norms do not necessarily limit the teachings of Buddhism, and individuals are encouraged to strive for ethical behavior and to act in a way that promotes the well-being of all beings.
