Arcadia was one of the centres of the [[Greek War of Independence]] which saw victories in their battles including one in [[Tripoli, Greece|Tripoli]]. After a victorious revolutionary war, Arcadia was finally incorporated into the newly created Greek state.  Arcadia saw economic growth and small emigration.

In the 20th century, Arcadia experienced extensive population loss through emigration, mostly to the [[Americas]].  Many Arcadian villages lost half their inhabitants, and fears arose that they would turn into ghost towns.  Arcadia now has a smaller population than [[Corinthia]].  Demographers expected that its population would halve between 1951 and the early 21st century.  The population has fallen to 87,000 in 2011.

An earthquake measuring 5.9 on the [[Richter magnitude scale]] shook Megalopoli and the surrounding area in 1965. Large numbers of buildings were destroyed, leaving people homeless. Within a couple of years, the buildings were rebuilt anti-seismically. This earthquake revealed an underground source of [[lignite]] in the area, and in 1967 construction began on the [[Megalopoli Power Plant]], which began operating in 1970. The mining area south of the plant is the largest mining area in the peninsula and continues to the present day with one settlement moved.

In July and August 2007 [[2007 Greek forest fires|forest fires]] caused damage in Arcadia, notably in the mountains.

In 2008, a theory proposed by classicist Christos Mergoupis suggested that the mummified remains of Alexander the Great (not his actual tomb), may in fact be located in Gortynia-Arkadia, in the Peloponnese of Greece. Since 2008, this research is ongoing and currently being conducted in Greece. The research was first mentioned on CNN International in May 2008.<ref>{{cite web|url=http://ireport.cnn.com/docs/DOC-24455 |title=Alexander the Great New Research: Are His Mummified Remains In Gortynia-Arkadia, Greece? |publisher=Ireport CNN |date=2008-05-20 |access-date=2013-01-06}}</ref><ref>{{cite web|url=http://ireport.cnn.com/docs/DOC-2018 |title=Alexander the Great Discovery-New Important Research Conducted in Greece |publisher=Ireport CNN |date=2008-02-22 |access-date=2013-01-06}}</ref>
