卫国 / Wey State
卫国 / Wey State appears in 《资治通鉴·周纪》10丨 以家族单位 有蚂蚁吃大象的精神（1） through a 373 BCE notice: Wey attacks 齐国 in the same year that 燕国 defeats Qi at Linghu and 鲁国 occupies Yangguan.
This page uses “Wey” to avoid colliding with 魏国 / Wei State, a different Warring States power already present in the wiki. The source also records the death of 卫声公 and the accession of 卫成公.
