Having no sons Julius Francis provided for the legal grounds of female succession in Saxe-Lauenburg. With his death, the Lauenburg line of the House of Ascania was extinct in the male line. So Julius Francis' two daughters Anna Maria Franziska and Sibylle fought for the succession of the former, the elder sister. Also, Julius Francis' cousin, Eleonore Charlotte of Saxe-Lauenburg-Franzhagen, claimed the succession.
