On the 20th of December 1821 the First National Assembly began its proceedings at Piada (ancient Epidauros). Representatives from the most revolted regions attended the assembly. The majority of the representatives were local notables and clergymen from Morea, Rumeli and the islands. The most significant act of the assembly was the Provisional Constitution of Epidauros, that is to say the first constitution of the revolted Greeks, in which the Declaration of Independence was included.
