In The Wake Of (something) 

Wake用作動詞指「（航行中的船等留下的）船迹、尾流」。由此引伸出來，in the wake of是指一件事情已告一段落，進入另一境界，從這個意思來說，wake跟eve（前夕）的意義剛剛相反。
On the eve of是指事件發生以前，in the wake of是發生以後。

in the wake of (something)

as a result of something, following something

In the wake of the large number of people who have recently left our company we will need to hire some new people.
