The designation Braganza-Saxe-Coburg and Gotha is prevalent mainly in the writings of non-Portuguese historians and genealogists, as European custom classifies a descendant branch on the basis of patrilineal descent, which means that the House of Braganza-Saxe-Coburg and Gotha is a cadet branch of the House of Saxe-Coburg and Gotha-Koháry.

[1] The royal house was founded by Prince Ferdinand of Saxe-Coburg and Gotha, who on 9 April 1836 married Queen Maria II of Portugal.

[4] On 15 November 1853, Queen Maria II died, and her eldest son succeeded to the throne as Pedro V, the first king of the Braganza-Saxe-Coburg and Gotha dynasty.

Before his death in 1932, King Manuel II had been in negotiations with the rival Miguelist branch of the House of Braganza, who had claimed the Portuguese throne since 1834, in opposition to the Braganza-Saxe-Coburg and Gotha dynasty.

On the King's death, the claim to the defunct throne of Portugal passed to Miguelist descendant Duarte Nuno of Braganza.
