Today, the Feast of St. George, is the National Day of England: the English people are a nation and ethnic group native to England who speak English. Their country has had a significant historical, cultural and legal impact on the whole world.
23rd April was also the date of the beginning of the reign of Alfred the Great - clearly one of the best kings ever and the only English monarch to be nicknamed "The Great" but it was his grandson Athlestan the Glorious who became the first King of England i.e. bringing the whole of England under one ruler for the first time.
That's not all: "April 23rd, the happy conjunction of St George’s Day and Shakespeare’s birthday should be a love feast for England to which all are invited." [Telegraph]
