Elisabeth Auguste of Neuburg was the only surviving child of Charles III Philip, Elector Palatine.
Background
The Palatinate-Neuburg line went extinct with her father and was succeeded by the Palatinate-Sulzbach line. She was the third daughter of Charles III Philip, then Count Palatine of Neuburg, and his first wife, Ludwika Karolina Radziwiłł. One of her sisters, Maria Anna, died before Elisabeth Auguste was born, aged one or two, and her sister Leopoldine died the year she was born, aged three.
Career
Her sons with Count Palatine Joseph Charles of Sulzbach would have been the indisputable heirs to the Electorate of the Palatinate, but they all died in infancy. She was the Hereditary Princess of Sulzbach by marriage. Of Charles Philip"s six children (five daughters and one stillborn son), Elisabeth Auguste was the only one to reach adulthood.
Her mother died on 25 March 1695, when Elisabeth Auguste was about two years old, and her father remarried when she was about eight years old to Princess Teresa Lubomirska.
Her two half-sisters from her father"s second marriage both died before turning three. lieutenant was also obvious that the related Palatinate-Sulzbach line would succeed them.
Joseph Charles, the eldest son of the Count Palatine of Sulzbach, was the clear heir. On 2 May 1717, Elisabeth Auguste married Joseph Charles in a move that united the two lines.
The sons of the union would be the indisputable heirs of the Electorate of the Palatinate, preventing another succession war.
Elisabeth Auguste died in childbirth in 1728. Her husband died the following year in Oggersheim. Their daughter, also named Elizabeth Augusta, married Charles Theodore and became Electress.
