鲁国 / Lu State
鲁国 / Lu State appears in 《资治通鉴·周纪》07丨两起刺杀（2） through a 394 BCE notice: 齐国 attacks Lu and occupies Zui, located southeast of present-day Qufu in the source’s geography.
The page is source-scoped. Lu’s role here is a territorial-war notice in the episode’s broader claim that early 战国时期 conflict is becoming faster and more frequent.
《资治通鉴·周纪》09丨战国时代的世界大战 adds a compact 377 BCE succession notice: 鲁穆公 dies and his son Ji Fen succeeds as 鲁共公. The same episode’s 子思 biography also keeps the Confucian branch near Lu’s cultural setting.
