English: During the Greek War of Independence, Nafplion was a major Ottoman stronghold and was besieged for a whole year by Theodoros Kolokotronis. After its capture, because of its strong fortifications, it became the seat of the provisional governments of Greece. Kapodistrias made it the official capital of Greece in 1829. After his assassination there in 1831 a period of anarchy followed, until the arrival of King Otto and the establishment of the new Kingdom of Greece. Nafplion remained the capital of the kingdom until 1834, when King Otto decided to move the capital to Athens.
