The House of Saxe-Coburg-Saalfeld was a German ducal family that originated in the early 19th century. It was a branch of the larger House of Saxe-Coburg and played a significant role in European royal history. The family produced several notable monarchs, including Queen Victoria of the United Kingdom, through her marriage to Prince Albert. In 1826, the house split into two branches: Saxe-Coburg and Saxe-Coburg-Saalfeld. The latter became prominent in the governance of various German states. The family's influence extended beyond Germany, impacting royal lineages across Europe, including the Belgian and Portuguese thrones.
