What happened
After Kapodistrias's assassination, the Great Powers settled on Otto, the seventeen-year-old second son of King Ludwig I of Bavaria, as king of the new Greek state; the Treaty of London finalized his nomination on 7 May 1832, and Otto arrived at Nafplion in January 1833. He initially ruled through a Bavarian regency council, then took direct control as an absolute monarch, a period of tension with his Greek subjects that ended only when an 1843 uprising forced him to grant a constitution. During the National Assembly debates leading to that Constitution of 1844, Prime Minister Ioannis Kolettis argued before Otto that the Kingdom of Greece was only "the smallest, poorest part of Greece," and that true Greeks also lived in Ioannina, Thessaloniki, and Constantinople, calling Constantinople "the great capital, the dream and hope of all Greeks." This speech is credited as the first formal statement of the Megali Idea, the Great Idea, the vision of a Greater Greece encompassing all historically Greek territory with its capital restored to Constantinople.
Why it matters
The Megali Idea became the organizing goal of Greek foreign policy for the better part of a century, driving the territorial ambitions behind the Balkan Wars and the catastrophic 1919-1922 campaign into Asia Minor. Otto's own troubled reign, caught between Bavarian absolutism and Greek demands for constitutional government, previewed the recurring conflict between imported monarchy and Greek popular sovereignty that would keep resurfacing until the monarchy's final abolition in the 20th century.
How we know
Otto's nomination, arrival, and reign are documented in Greek cultural-institutional archives of the founding of the modern kingdom, and Kolettis's 1844 speech and its role in launching the Megali Idea are documented in university historical scholarship on Greek nationalism.
