Greece had been a part of the Ottoman Empire since 1453, but the Greek revolt was triggered when Bishop Germanos of Patras raised the flag of revolution over the Monastery of Agia Lavra.
With the motto "Freedom or Death", the Greeks at first experienced early successes on the battlefield, including the capture of Athens in 1822, but by 1827 the Turks had recaptured Athens and most of the Greek isles. Just when the revolution looked to be a failure, Great Britain, France and Russia came to the aid of the revolutionaires and their combined forces destroyed the Ottoman fleet in the Battle of Navarino.
Greece was finally recognized as an independent nation in May of 1832 with the signing of the Treaty of Constantinople.
Greek Independence Day is celebrated in towns and villages throughout the country with parades, during which school children march in traditional Greek costumes and carry Greek flags. In Athens, there is an armed forces parade.
Consider that this jersey is now over 20 years old and pre-dates any NHL alternate jersey. The Mighty Ducks of Anaheim weren't even a team yet, so there was no such thing as a diagonal stripe in the NHL at the time!
This style was worn by Greece on it's international debut at the 1992 Group C2 World Championships in South Africa where the Greeks captured the bronze medal their first time out. Many international jerseys from the less funded nations of the lower divisions are frequently recycled several times during their lifespan, the fact this jersey still has the nameplate still intact makes it even more desirable.
This style was used in 1991 by the junior team and then 1992 and 1993 by the senior level team until the Tackla jerseys were rebranded as Reebok for two years prior to Nike taking over the production of IIHF jerseys.
