Bona Sforza (2 February 1494 or 2 February 1493 – 19 November 1557) was a member of the powerful Milanese House of Sforza. In 1518, she became the second wife of Sigismund I the Old, the King of Poland and Grand Duke of Lithuania, and became the Queen of Poland and Grand Duchess of Lithuania.

She was the third child of Gian Galeazzo Sforza and his wife Isabella of Naples. Her older brother was Francesco Sforza and her sisters were Ippolita Maria and Bianca Maria. All of Bona's siblings died young.

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 into the powerful and wealthy Italian Sforza dynasty who had ruled Milan since 1447. Although her father belonged to the authority of the Duchy of Milan, he was ousted by his uncle Ludovico Sforza, known to history as "Il Moro". He exercised power on behalf of the young prince, until his death in 1494 at the castle in Pavia. Shortly afterwards, the Princess Isabella, together with her daughters, went to Bari. To regain political significance and their former possessions, Isabella had to find a husband for Bona (her surviving daughter). Her first attempts were unsuccessful due to the unfavourable political situation at the time but due to the support of the House of Habsburg she succeeded in marrying Bona to the widowed Polish King Sigismund I the Old. The marriage ceremonies and Bona's coronation were held in Krakow on 18 April 1518.

Ciriaco Sforza (born 2 March 1970) is a Swiss former professional football player and is the coach of Grasshopper-Club Zürich.

He most notably played for 1. FC Kaiserslautern and FC Bayern Munich in Germany. Ciriaco Sforza represented the Swiss national team 79 times, and represented his country at the international 1994 World Cup and Euro 96 tournaments.

According to his website, he is married and has two children.

Born in Swiss town Wohlen, Sforza started his career in his hometown club FC Wohlen. He was signed by FC Aarau in 1989, where he impressed commentators and fans alike. Sforza was signed by Swiss giants Grasshoppers Zurich one year later and he represented Grasshoppers during three successful seasons. He won the 1991 Swiss Super League championship with the club, and made his national team debut in August 1991. In 1993, he moved abroad to Germany to play for 1. FC Kaiserslautern.

Sforza became the general of the Kaiserslautern midfield and was recognised as one of the best midfielders in the German Bundesliga championship. After two seasons at Kaiserslautern, he was bought by German giants FC Bayern Munich in 1995. Sforza was signed at the same time as German superstar Jürgen Klinsmann, compared to the homely smalltown club Kaiserslautern, FC Bayern was a team with many stars. Conflicts between Klinsmann and team captain Lothar Matthäus poisoned the atmosphere and many scandals underlined why FC Bayern is nicknamed FC Hollywood. Bayern also missed out on the German championship for the second season in a row, though Sforza was a part of the 1996 UEFA Cup winning FC Bayern team.
