History of The Delaine Merino Sheep

The merino sheep breed originates from Spain. For many years, exporting a merino sheep was considered a criminal offense punishable by death by the Spanish government.

However, after dominating the European wool trade until the 19th century, the Spanish king relinquished some of his merino flock to his French cousin Louis XVI in Rambouillet. The Rambouillet sheep originated from this merino sheep donated by the Spanish leader.

Upon the fall of the Spanish empire, many different merino breeds were exported to most European countries and other parts of the world, including Britain, Australia, and the US.

As of 1900, merinos of different kinds were spread worldwide. Most Delaines found their way to the US, where they remain the most predominant to date. Many farmers in Western and Southwestern states keep them for wool.
