安政の大獄 The Great Suppression in Ansei

当時の状況下で国内の秩序が乱れ、無闇に西洋諸国と戦争すれば、アヘン戦争に引き込まれた清の二の舞を演じることになってしまうことは明白でした。

It was apparent that if the national order is disturbed during such time and Japan is led to the wars against the Westerners, Japan would face the devastating consequence as China was led to the Opium War.

そこで、井伊直弼は幕府の政策に反対し、従来の規定に背いた多くの武士や知識人を蟄居させるか容赦なく処刑していきました。

So, he confined or ruthlessly executed so many of those Samurai and intellectuals who were opposing to Bakufu’s policies and violationg the conventional regulations.

これに憤り、国の将来を真剣に憂いた18人の水戸藩士と薩摩藩士は井伊直弼の暗殺をともに決めました。

Resenting his tyrant authoritarianism and seriously concerning about Japan’s future, the 18 Samurai of Mito Domain and Satsuma Domain corroboratively decided to assassinate him.

そして、藩が責めを負わないよう脱藩した後、1860年井伊直弼を暗殺しました。

Before the assassination was actually carried out in 1860, they had removed their names off from their Domains’ registers so that their Domains wouldn’t be held accountable for it.
