The Kladruber, known in Czech as Starokladrubský kůň (Old Kladruber Horse), takes its name from the village of Kladruby nad Labem in Bohemia where the breed has been developed for over 400 years. Alternative spellings include Kladruby and Kladrub, with the breed sometimes historically referred to as Equus Bohemicus, reflecting its status as Bohemia's—now the Czech Republic's—oldest and most distinctive horse breed.
The National Stud at Kladruby nad Labem serves as the chief breeder and keeper of the studbook, maintaining this role since the stud's founding in 1579 by Emperor Rudolf II of the Holy Roman Empire. This stud farm represents one of the oldest continuously operating horse breeding establishments in the world, predating even the famous Lipizzan stud at Lipizza by one year.
The breed maintains two distinct color lines with separate breeding programs: gray Kladrubers bred at the main stud in Kladruby nad Labem, and black Kladrubers currently bred at the Research Institute for Horse Breeding in Slatiňany. While sharing the same ancestry and type, these color populations developed somewhat differently due to their separate roles—grays for imperial court ceremonies and blacks for high-ranking church officials.
In 1995, the extensive complex of the National Stud, including the Kladruber breed itself, was declared a Czech cultural monument. More significantly, in 2019 the Imperial Stud Farm and its surrounding landscape achieved UNESCO World Heritage Site status, recognized as an exceptional example of equestrian cultural development. The breed is also included in the Czech Republic's National Programme for genetic resource conservation.
