Editing Duke (section)

=== Empire of Brazil ===
In the [[Empire of Brazil]] duke was the highest rank for people born outside the imperial house and only three dukedoms were created. Two of these titles were for relatives of [[Pedro I of Brazil|Emperor Pedro I]]: an illegitimate daughter and a [[Auguste de Beauharnais, 2nd Duke of Leuchtenberg|brother-in-law]] who received the title when married to Pedro I's daughter [[Maria II of Portugal|Maria II]]. The third, given to [[Luís Alves de Lima e Silva, Duke of Caxias|Luís Alves de Lima e Silva]], was the only dukedom created during the reign of [[Pedro II of Brazil|Pedro II]]. None of these titles were hereditary, just like every other title in the Brazilian nobility system.
