What is the setting of The Unbearable Lightness of Being by Milan Kundera?

The Unbearable Lightness of Being is set during the 1960s in Czechoslovakia. The fact that Kundera himself experienced the Prague Spring as well as the Soviet takeover lends special poignancy to the story. Kundera uses his setting for several important purposes. The Unbearable Lightness of Being is a love story and juxtaposing the love affairs of the four main characters with the upheaval of the Russian invasion throws the issues of love into sharp contrast with the issues of hate.
