In March 1821, the Greek War of Independence broke out, an effort by the Greeks to free themselves from the Ottoman rule by declaring independence. The struggle to secure independence would continue until 1832. Later in the year, deputies from various provinces of Greece assembled at Piada (near Epidaurus, and today known as Nea Epidauros) in the First National Assembly to draft the first Greek Constitution, which was published on 1 January 1822. The Constitution of 1822 was the first of many which would lead to the modern Constitution.
