La obra que precedió al gran éxito de Ponchielli, La Gioconda, y en la que ya está patente la riqueza melódica orquestal y vocal de este compositor, maestro de Puccini y Mascagni.
Casa Ricordi commissioned Ponchielli to write the opera, and the idea to use Konrad Wallenrod came from Salvatore Farina, a novelist and playwright working for Ricordi. The opera was extremely well received when it opened, and a second, final version with additional material was performed again a year later also to good reviews. It continued to be performed in the last decades of the 19th century in Cremona, Trieste, Brescia, Rome, Turin, Buenos Aires, Montevideo, Chicago, and a single noteworthy Russian performance in 1884 at the Imperial Bolshoi Kamenny Theatre in Saint Petersburg with the title Aldona.
After a three-night run in 1903 at La Scala, where the casting was particularly poorly reviewed, I Lituani was not performed again until 1979 when RAI recovered the score. Since then, it has been revived in Chicago (1981, 1983 and 1991), Toronto (1981), Cremona (1984), Vilnius (1991) and Trakai (2009).
Corrado Wallenrod, actually a Lithuanian named Walter who is impersonating a loyal Teutonic Knight, allows the Lithuanians to win against the Teutons by executing a long-planned misdirection. Aldona, his wife who has entered a convent, searches for her love Walter, and finds him just before he is sentenced to death for his deception.
From the battlements of a castle in Lithuania, Albano, an aged bard, moans that his country is being destroyed by the Teutons. Aldona, a Lithuanian princess, wonders about her brother, Arnoldo, and Walter, her husband, and invites everyone to pray. Arnoldo and Walter return and announce a heinous betrayal by Vitoldo, one of their leaders, which has led to the defeat of the Lithuanian army. Walter tells his wife about plan to defeat the Teutonic Knights, and swears his eternal love for her before leaving to avenge the Lithuanians.
 Act 1
Ten years later, in the cathedral square of Marienburg, the Teutonic Knights celebrate the new Grand Master of the Teutonic Order, Corrado Wallenrod, who is actually Walter. Vitoldo is furious, because he believes he should be Grand Master. Ten Lithuanian prisoners in chains are brought to be sacrificed in Corrado's honour at the celebration; Arnoldo is one of them. Corrado unexpectedly frees them, and afterwards Arnoldo realizes that Corrado is actually Walter. Arnoldo runs into his sister, Aldonda, who has come to Marienburg after entering a convent, hoping to find Walter. Albano, Arnoldo, and Aldona set out to find Walter in the castle.
In a large hall of the castle where the celebration is being held, Corrado invites everyone to dance and sing. Arnoldo and Aldona, disguised as bards, sing about the sad fate of Lithuania, predicting its imminent liberation. The Teutonic Knights object, and Corrado hurls himself towards Arnoldo, while Aldona tries to separate them. Corrado orders the knights to sheath their swords, and Albano tries to convince Corrado not to give his true identity away. Vitoldo recognizes Aldona, but Corrado orders the judgement against Aldona and Arnoldo be adjourned so that the celebration can continue.
Aldona comes out of the ruins of a cloister, where a battle between the Lithuanians and Teutonic Knights is taking place nearby. She meets Walter, and hopes for a happy future of love, but Walter has been betrayed for causing the defeat of the Teutonic Knights by the Lithuanians. Later, back in the castle, Albano tells Walter that a secret court has sentenced Walter to death. Rather than falling into enemy hands, Walter drinks poison and exults the victory of the Lithuanians, and asks Albano to give Aldona his last farewell. Aldona arrives, and Walter dies in her arms. The Willi, divine spirits of Lithuania, arrive to welcome the glorious warrior's soul.
