Geographical barriers to travel and communication kept the Tsakonians relatively isolated from the rest of Greece until the 19th century, although there was some trade between the coastal towns. The rise of mass education and improved travel beginning after the Greek War of Independence meant that fluent Tsakonian speakers were no longer as isolated from the rest of Greece. In addition, during the war, the Turkish army drove the Tsakonians east, and as a result, their de facto capital shifted from Prastos to Leonidio, further making the people significantly less isolated. There began a rapid decline from an estimated figure of some 200,000 fluent speakers to the present estimate of a speaker count between 200 and 1,000.
