Ioannis Kolettis

Ioannis Kolettis (; 1773 or 1774 – 5 September 1847) was a Greek politician who played a significant role in Greek affairs from the Greek War of Independence through the early years of the Greek Kingdom, including as Minister to France and serving twice as Prime Minister. Kolettis is credited with conceiving the Byzantine restorationist and irredentist Megali Idea or "Great Idea" which became the core of Greek foreign policy until the early 20th century.
