Isabella II (Spanish: Isabel; 10 October 1830 – 9 April 1904), also known as La de los Tristes Destinos (The One with the Sad Destinies), was Queen of Spain from 1833 until 1868.
She came to the throne as an infant, but her succession was disputed by the Carlists, whose refusal to recognize a female sovereign led to the Carlist Wars.
After a troubled reign, she was deposed in the Glorious Revolution of 1868, and formally abdicated in 1870.
