The Polish Halfbred, also known as Polski Koń Półkrwi, is a prominent warmblood sport horse type originating from Poland. Developed primarily after World War II, it resulted from carefully crossing native Polish mares with Thoroughbred, Arabian, and German warmblood stallions such as Trakehners and Hanoverians. This breeding aims to produce an athletic and versatile horse suited for Olympic disciplines like show jumping, dressage, and eventing. Physically, the Polish Halfbred typically stands between 15.3 to 17 hands high, featuring a refined head, well-proportioned build, strong limbs, and elastic, powerful movement. Its temperament is generally intelligent, willing, and trainable, making it suitable for both amateur riders and professionals. Known for its good work ethic and courageous nature, the breed adapts well to various equestrian sports. The Polish Halfbred is mainly registered in Polish studbooks such as the Poznań studbook and forms the genetic base for many successful Polish sport horses. Keywords such as "Polish Halfbred horse," "Polish warmblood," and "sport horse Poland" highlight its significance in the UK's equestrian circles, especially for those seeking a versatile, performance-oriented sport horse.
