 Among the foundation horses was the mare Murana I 1808, whose dam line still continues at Marbach today.The stallions Bairactar, imported directly from the Arabian desert and his son Amurath I 1829 played a significant part in the development of the Arabian breed at Weil, and made major contributions to the breed throughout Europe, particularly on Arabian horses bred in Poland.While this establishment thrived though the 19th century, from 1890 on, it went into considerable decline and by the time the Weil herd was transferred from Princess Pauline zu Wied of Württemberg to the Marbach State Stud in 1932, only 17 purebred Arabians remained.
