Just like the whole of Gortynia, Lagadia flourished during the 18th and 19th centuries. In the decade of 1890s in fact they were the largest town of Arcadia, second only to Tripoli, with a population of almost 7000 residents. From the middle of the 20th century however Lagadia witnessed an inevitable decline. This is due to the dramatic changes in the production and economic model of contemporary Greece, and the phenomenon of urbanism that was observed all over the Greek countryside.Moreover of course because of the external immigration that took place around the same period.
Lagadia are the home place of Kanelos Deligiannis, of Karavogiannis, of Dimitrios Dimitrakopoulos - Vogizas, and also of Nikos Ploubidis.
