Bona Sforza was a member of the House of Sforza who in 1518 became the second wife of Sigismund I of Poland.
When her mother Isabella of Naples died in 1524, Bona succeeded to the titles Duchess of Bari and Princess of Rossano. She also became the holder of the Brienne claim to the title of King of Jerusalem.
Bona was born in Vigevano, daughter of Gian Galeazzo Sforza of Milan and Isabella of Naples. She was the niece of Bianca Maria Sforza, who in 1493 married Holy Roman Emperor Maximilian I. She was named after her grandmother, Bona of Savoy.
Bona married King Sigismund I of Poland. The marriage and coronation took place in Wawel Cathedral, Kraków, on 18 April 1518.

She is also considered to have influenced the Polish and Lithuanian cuisines, having introduced many new dishes to the Commonwealth.
Upon her husband's death, she sided with many in Catholic Poland in opposing her son King Sigismund II Augustus' marriage to the Lithuanian Calvinist, Barbara Radziwi??, and was suspected, without evidence, of having poisoned the new queen, who died shortly after her coronation.
In 1556, she returned to Bari, Italy where she was poisoned by her private secretary Gian Lorenzo Pappacoda. Pappacoda was acting on behalf of King Philip II of Spain, who wished to avoid repaying his sizable debts to the Polish queen. She dided on 19 November 1557.
She was succeeded by her three children. Her only surviving son, Sigismund August Jagellon, became the king of Poland. After her brother's death, Anna the Jagiellonian was elected King of Poland in the second election for the king, and ruled Poland with her elected husband king Stephen Bathory. The title of King of Jerusalem passed to the youngest daughter Catherine Jagellonica, Queen of Sweden, who passed it on to her son, also elected King Sigismund III Vasa of Poland.
