On 27 February 1881, Augusta married her half-second cousin Prince Wilhelm of Prussia. Augusta's maternal grandmother Princess Feodora of Leiningen was the half-sister of Queen Victoria, who was Wilhelm's maternal grandmother. Wilhelm had earlier proposed to his first cousin, Princess Elisabeth of Hesse and by Rhine (known in the family as "Ella"), a daughter of his mother's sister, but she declined. He did not react well, and was adamant that he would soon marry another princess.
