In June 2012, newly-elected MP and National League for Democracy leader Aung San Suu Kyi quoted from this poem in an address to both Houses of Parliament in London. The poem was also used by Churchill to encourage America to join with Britain in World War 2.
The poem is by Arthur Hugh Clough (1819-1861) and is read by Tom O’Bedlam in his SpokenVerse channel on Youtube, with hundreds of other poems.
