Idiom: in the wake of something
Note: What is a wake?
A wake is the track a boat creates behind it as it moves through water. In this photo, you can see the wake with the white path of water and waves behind the boat.
So the first definition of this idiom means happening after something (moving in the same path or traveling close behind something).
In addition, a wake produces waves. Other boats and objects can be negatively affected or endangered by the wakes of a boat. In this sense, the idiom in the wake of something, describes something happening as a result or consequence of something (usually something that is bad or negative).
