Tsar Gorokh — Russian fairy tale character

Tsar Gorokh is a character from Russian folklore, a fictional tsar whose name literally means "pea". The exact origin of the name is unknown.
The name "Tsar Gorokh" appears in a number of Russian-language expressions as a reference to times immemorial, as in "during the times of Tsar Gorokh". Some preambles of Russian fairy tales set their scene in this way. In common speech the reference often conveys an ironical sense, as an indication of unbelievable or obsolete circumstances.
