At the time of the wedding, Charles was fighting for his claim to the Spanish throne against the French candidate Philip, so he was living in Barcelona. Elisabeth Christine arrived in Spain in July 1708 and married Charles on 1 August 1708 in the church of Santa María del Mar, Barcelona. As Philip had already fathered a son, Elisabeth Christine was immediately pressured to produce a son. During her time in Spain, she had a long-term correspondence with her mother, which was reportedly a consolation for the continuous pressure to produce a son.
