For example, the most common form of polygamy is polygyny or the marriage of one man to two or more women.

例如，最常见的一夫多妻制形式是一夫多妻制或一个男人与两个或更多女人结婚。

Each tribe was led by a ruling class or a ruling royal family, and these ruling classes tended to intermarry to keep the bloodline pure – while also practicing polygyny.

每个部落都由统治阶级或统治王室领导，这些统治阶级倾向于通婚以保持血统纯正——同时也实行一夫多妻制。
