Kyriakoulis Petrou Mavromichalis (Greek: Κυριακούλης Μαυρομιχάλης, 1850–1916[1]) was a Greek politician of the late 19th and early 20th centuries who briefly served as the 30th Prime Minister of Greece.
Under pressure from the League, Mavromichalis passed a large amount of ground-breaking legislation that the League demanded, including organization of the army, the justice and educational systems, and governmental organization.
Mavromichalis resigned as Prime Minister in January 1910, after a disagreement with the Military League. He died in Athens in 1916 and was buried with full honours.
