What was one of the first big Imperial events in Asia/China?

ONE of them that I know well was the massacre of the last of the Samurai. A band has made a song on it known as Shiroyama. 500 Samurai were left after a long time of modernization. Given they still followed the old ways, they didn’t have the same equipment as the Imperial forces which had early versions of firearms. After the last of the Samurai were in an encounter with imperial forces, it was swords brought to a gunfight. After the battle, all of the Samurai perished and their ways died out over time.

Include the poem for more info but this is what i know about the goddess athena athena is a greek goddess of war and sprang from zeus head full grown in a full set of battle armor.
