La santa alleanza (English: The Holy Alliance) is an 1822 cantata composed by the Italian Gioachino Rossini.
Held in the Austrian-ruled city of Verona, it was the largest gathering of international figures since the Congress of Vienna seven years earlier.
[1] While Ludwig van Beethoven had been chosen to compose music to be performed at Vienna, in 1822 Klemens Von Metternich turned to the Italian Rossini.
The cantata was a celebration of the Holy Alliance that involved several Continental European powers, most notablly Austria, Prussia and Russia.
[2] Amongst the works performed was a resetting of music from the 1810 opera La donna del lago with fresh lyrics.
