Yiannis Makriyiannis, born Ioannis Triantaphyllou, was a Greek merchant, military officer, politician and author, best known today for his Memoirs. Starting from humble origins, he joined the Greek struggle for independence, achieving the rank of general and leading his men to notable victories, most notably the successful defense of Nafplio in the Battle of the Lerna Mills. Following Greek independence, he had a tumultuous public career, playing a prominent part in the granting of the first Constitution of the Kingdom of Greece and later being sentenced to death and pardoned.

The Greek War of Independence, also known as the Greek Revolution or the Greek Revolution of 1821, was a successful war of independence by Greek revolutionaries against the Ottoman Empire between 1821 and 1829. In 1826, the Greeks were assisted by the British Empire, Kingdom of France, and the Russian Empire, while the Ottomans were aided by their North African vassals. The war led to the formation of modern Greece, which would be expanded to its modern size in later years. The revolution is celebrated by Greeks around the world as independence day on 25 March.
