Manuel da Silva Passos (5 January 1801 – 16 January 1862) was a Portuguese jurist and politician, one of the most notable personalities of 19th-century Portuguese Liberalism.
Also notably, he entrusted Almeida Garrett with drawing up a plan to promote national theatre, which resulted in the creation of Queen Maria II National Theatre and the National Conservatory of Dramatic Art.
He also introduced the 1836 Administrative Code, the first of its kind in Portugal.
A declaration of principles written by Passos Manuel became famous: "I am a Minister of the Queen — the Queen is the head of the whole nation.
And before I was for the Left, I was for the Fatherland.
The Fatherland is my policy."He married Gervásia Joaquina Farinha de Sousa Falcão on 28 December 1838, and they had two daughters: Beatriz de Passos Manuel, who was granted the title of Viscountess of Passos by King Peter V in 1861 as a reward for her father's services; and Antónia de Passos Manuel, who married Pedro de Sousa Canavarro, grandson of the 1st Baron of Arcossô.
