Some famous female roles in the history of opera have only been possible because 19th-century composers started giving important roles to mezzo-sopranos.
By the Baroque period (1600-1750), opera had taken Europe by storm, a spectacular and expensive affair filled with ornate arias and elaborate sets with moving parts. One of the greatest composers of Italian baroque opera was George Friedrich Handel (1685-1759), a German who spent most of his life in London.
