What is Erasmus?
The Erasmus+ Programme is a European funding programme established in 1987 offering university students a possibility of studying or doing an internship abroad in another country for a period of at least 2 months and maximum 12 months per cycle of studies. Erasmus+ now offers the possibility to go way beyond the European borders as well.
More details of the programme you can find on European Commision website and the official Erasmus Students Network (ESN) web page.
Erasmus in Greece is run by the National Foundation for Scholarships - IKY
