St Andrew preached Christianity on the territories of Asia Minor, the Black sea, along Danube, Volga and Dnieper. Hence he became a patron saint of Ukraine, Romania and Russia. According to tradition, he founded the Church of Byzantium in AD 38 and is consequently the patron saint of the Ecumenical Patriarchate of Constantinople. Andrew is also the patron saint of Scotland, Greece, Patras in Greece, Amalfi in Italy, Luqa in Malta, and Esgueira in Portugal; of Prussia (the historic German kingdom) and of the Order of the Golden Fleece (an order of chivalry founded in Bruges in 1430). Andrew also protects the fishermen (being a fisherman himself) and unmarried women.
The feast of St Andrew is observed on November 30 in the Catholic tradition, and on December 13 according to the Orthodox church calendar. In Scotland November 30 is also the national day.
The symbols of St Andrew are the fishing net and the saltire cross.
