In his comedies, Fredro has shown mastership in character's profile, in action forming, and flexibility of the language. He has introduced to his pieces some humoristic elements, a typical parts of folk theatre humor, in that time characteristic only of farce.
Fredro's tales, for example Małpa w kąpieli (Monkey in bath) or Paweł i Gaweł (Paweł and Gaweł) are children's reading books. The most known Fredro's comedy is Zemsta (Vengeance).
From 1809 to 1814, Fredro served in the Polish regiments of Napoleon I's army, taking part in the invasion of Russia.
He returned to the family estates in Poland, devoting himself to the life of a country gentleman and writing plays that were at first influenced by the Molière and Goldoni works he had seen in Paris.
Fredro's plays are notable for their brilliant characterization, complex plots, and idiomatic, colorful language.
