Agrippina is an opera seria in three acts by George Frideric Handel with a libretto by Cardinal Vincenzo Grimani. Composed for the 1709–10 Venice Carnevale season, the opera tells the story of Agrippina, the mother of Nero, as she plots the downfall of the Roman Emperor Claudius and the installation of her son as emperor. Grimani's libretto, considered one of the best that Handel set, is an "anti-heroic satirical comedy", full of topical political allusions. Some analysts believe that it reflects Grimani's political and diplomatic rivalry with Pope Clement XI.

Handel composed Agrippina at the end of a three-year sojourn in Italy. It premiered in Venice at the Teatro San Giovanni Grisostomo on 26 December 1709. It proved an immediate success and an unprecedented series of 27 consecutive performances followed. Observers praised the quality of the music—much of which, in keeping with the contemporary custom, had been borrowed and adapted from other works, including the works of other composers. Despite the evident public enthusiasm for the work, Handel did not promote further stagings. There were occasional productions in the years following its premiere but Handel's operas, including Agrippina, fell out of fashion in the mid-18th century.

In the 20th century Agrippina was revived in Germany and premiered in Britain and America. Performances of the work have become ever more common, with innovative stagings at the New York City Opera and the London Coliseum in 2007. Modern critical opinion is that Agrippina is Handel's first operatic masterpiece, full of freshness and musical invention which have made it one of the most popular operas of the ongoing Handel revival.

Background

Handel's earliest opera compositions, in the German style, date from his Hamburg years, 1704–06, under the influence of Johann Mattheson. In 1706 he traveled to Italy where he remained for three years, developing his compositional skills. He first settled in Florence where he was introduced to Alessandro and Domenico Scarlatti. His first opera composed in Italy, though still reflecting the influence of Hamburg and Mattheson, was Rodrigo (1707, original title Vincer se stesso ê la maggior vittoria), was presented there. It was not particularly successful, but was part of Handel's process of learning to compose opera in the Italian style and to set Italian words to music.

Handel then spent time in Rome, where the performance of opera was forbidden by Papal decree, and in Naples. He applied himself to the composition of cantatas and oratorios; at that time there was little difference (apart from increasing length) between cantata, oratorio and opera, all based on the alternation of secco recitative and aria da capo. Works from this period include Dixit Dominus and the dramatic cantata Aci, Galatea e Polifemo, written in Naples. While in Rome, probably through Alessandro Scarlatti, Handel had become acquainted with Cardinal Grimani, a distinguished diplomat who wrote libretti in his spare time, and acted as an unofficial theatrical agent for the Italian royal courts. He was evidently impressed by Handel and asked him to set his new libretto, Agrippina. Grimani intended to present this opera at his family-owned theatre in Venice, the Teatro San Giovanni Grisostomo, as part of the 1709–10 Carnevale season.
