Countess Anna Sibylle of Hanau-Lichtenberg (16 May 1542 – 5 January 1580[1]) was a German noblewoman.
She was born in Lichtenberg, the eldest surviving daughter of Count Philipp IV (20 May 1512 – 19 February 1590) and his wife, Countess Eleonore of Fürstenberg (11 October 1523 – 26 April 1544).
Anna Sibylle married on 12 October 1562 [2] to Louis of Fleckenstein-Dagstuhl (1542-1577).
They had a son: This marriage proved to be important to the history of the House of Hanau and the counties of Hanau-Münzenberg and Hanau-Lichtenberg, because her grandson Georg II of Fleckenstein-Dagstuhl played a major role during the final phase of the Thirty Years' War.
Georg II achieved the reunification of the two parts of Hanau, despite resistance of the Landgrave of Hesse-Kassel, who was the liege lord of Hanau-Münzenberg.
