First recorded in 1834 from thieves' slang cross (or on the cross) to refer to something dishonest, a play on straight/square, and therefore a crook going back on his partners would be crossing the crossers, or double-crossing.

double-cross (third-person singular simple present double-crosses, present participle double-crossing, simple past and past participle double-crossed)

To betray or go back on.
