What happened in 1585 – 95 that the French verb blandir (to soothe, caress, coax or flatter) around from the 1300s suddenly acquired an English noun, blandishments?
Possibly a rash of smooth-talkers down the local tavern or an outbreak of particularly wily politicians at court. Or maybe the English just started eating lots of this:

No doubt the real answer involves Shakespeare having something to do with it.
