Anna Leszczyńska, was a Polish noblewoman from the Leszczyński family and later Royal Princess of Poland when her father became King in 1704.
Background
Anna was the eldest daughter of Stanisław Leszczyński (who became King of Poland in 1704 and later Duke of Lorraine) and his wife, born Countess Catherine Opalińska.
Career
Her only sister, Maria Leszczyńska, was born in 1703 and later became Queen of France as the wife of Louis XV. She received a careful education. Anna died of pneumonia aged eighteen in Gräfinthal cloister, in the district of Mandelbachtal in Saarpfalz-Kreis. Many doctors called to her bedside by her father have likely accelerated her death, multiplying the purges and bleeding.
Her death devastated Leszczyński family, especially her father.
