Santana Lopes was born in Lisbon, Campo Grande, to Aníbal Luís Lopes (b. Lisbon, São Sebastião da Pedreira, 17 February 1933), a company administrator whose maternal grandfather's maternal grandfather was a relative of famous Portuguese Miguelist outlaw and bandit João Brandão, and wife (m. Lisbon, São Sebastião da Pedreira, 27 February 1954) Maria Ivone Risques Pereira de Santana (Lisbon, São Sebastião da Pedreira, 3 May 1931 – Lisbon, 23 March 1999), a half-great-great-great-niece of the 2nd Baron of Brissos.

He graduated as a Licentiate in Law from the Faculty of Law of the University of Lisbon, where he was Leader of the Student Union, becoming a lawyer. He joined the Portuguese Social Democratic Party (PSD) in 1976, and has remained a member ever since. There he started his career as a Deputy to the Assembly of the Republic.

Pedro Santana y Familias (Pedro Santana y Familias, 1st Marquis of Las Carreras) (June 29, 1801 – June 14, 1864) was a wealthy cattle rancher, soldier, politician and dictator of the Dominican Republic. He was born in the community of Hinche, which was part of the Colony of Santo Domingo. Currently, Hinche is a border town part of Haiti. He was the first constitutional President of the Dominican Republic, and the first Marqués de las Carreras.

His parents were Pedro Santana and Petronila Familias, landowners in the border zone. Around 1805, Santana moved with his family to El Cibao, and later to El Seibo at the eastern part of the country, where he eventually became a cattle rancher for 2 years.

He held the office of the presidency during the years 1844-1848, 1853–1856, and 1858-1861 (when Spain annexed the country). Thereafter, Santana became Governor, with the rank of Captain General of the territory. He continued in this post until 1862. He also received the Spanish noble title of Marqués de las Carreras, which was given as a recognition to his victory in the Battle of Las Carreras.
