Georgakis Plapoutas (Koliopoulos) was born in Palouba, Arcadia, around 1780. He was the eldest son of Kolias Plapoutas and Kyratso Tzortzis, and brother of the revolutionary Dimitrakis Plapoutas.
In 1818, he was initiated into the Filiki Etaireia, and in the spring of 1821, having assumed leadership of the family, he proclaimed the Revolution in mountainous Gortynia alongside his father and brother, assembling a force of approximately 800 armed men in the village of Betsi. Georgakis Plapoutas distinguished himself in the military engagements of the Revolution’s early phase. On 27 March 1821, he took part in the Battle of Karytaina, at the Pass of Agios Athanasios, confronting Muslim forces from the province of Fanari. A few days later, he was defeated in the battle at Salesi, Megalopolis, fighting alongside Elias Mavromichalis. In the Battle of Levidi, he faced Ottoman troops alongside the Petmezas family, and subsequently participated in the victorious Battle of Mantineia with Theodoros Kolokotronis and Kanellos Deligiannis. He fought alongside his brother Dimitrakis Plapoutas in the Battle of Valtetsi and at Agios Vlasios near Tripolitsa against the forces of Mustafa Bey, lieutenant of Hursit Pasha.
His final battle was at Lalas, in Elis, in 1821. His death, likely due to cerebral stroke, left his adolescent son, Giannikos, to continue the struggle under the guidance of his uncle Dimitrakis. The premature loss of Georgakis Plapoutas deprived the Revolution of a valuable and experienced military leader.
