Kincsem (; Hungarian for "My Precious" or "My Treasure"; March 17, 1874 – March 16, 1887) was a Hungarian Thoroughbred racehorse who has the longest undefeated record of any racehorse after winning all of her 54 races. The next closest in this regard is Black Caviar, who won all her 25 races. Foaled in Kisbér, Hungary in 1874, Kincsem is a national icon and widely considered one of the top racehorses of the 19th century. Over four seasons, Kincsem won against both female and male company at various race tracks across Europe, including multiple Classic race victories in the Austro-Hungarian Empire. She also raced frequently in Germany, winning the Grosser Preis von Baden three times. In her four-year-old campaign, she traveled to England to win the Goodwood Cup, then won the Grand Prix de Deauville in France. As a broodmare, Kincsem produced just five foals, one of which died young. Nevertheless, two of her foals became Classic winners and her daughters also proved to be outstanding producers. Her family has proved a lasting influence on the breed, with modern descendants including English Classic winners Polygamy and Camelot. Background Kincsem was bred at the stud of Ernő Blaskovich at Tápiószentmárton, in The Hungarian part of the Austro-Hungarian Empire. Her sire, Cambuscan, was bred by Queen Victoria and in 1864 went on to win the July Stakes and place in the St. Leger Stakes. He was sold to Hungarian interests and was brought to stand at the Hungarian National Stud in the Kisbér District in 1873. Cambuscan was by Newminster, while his dam, The Arrow, was by Slane. Kincsem was out of the Hungarian mare Waternymph, a daughter of the English horse Cotswold. Kincsem's third dam, Seaweed was also by Slane, making Kincsem inbred to him in the third and fourth generations (3x4). At that time, there were thieves in Hungary called betyars who stole cattle and horses. One night they tried to steal horses from an open summer stable of Blaskovich that had only a crossbar through the door. They made a noise, so stable staff chased them away and the horses, including Waternymph, were saved. This legend was later distorted and attributed to Kincsem, who in the new version was allegedly stolen by wandering Gypsies and later returned to her owner. Kincsem was once offered for sale as part of a package deal with six other yearlings for £700. However,
