Kincsem

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 female and male competitors at various race tracks across Europe, including multiple Classic race victories in the Austro-Hungarian Empire. She 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. In total, Kincsem defeated 85 different horses who had won over 400 races. She defeated 17 classic winners, including four consecutive Deutsches Derby winners (Double Zero, Pirat, Oroszvár, Künstlerin), three consecutive Prei der Diana winners (Chére Amie, Altona, Illona), a ''Poule d'Essai winner (Fontainebleau), Prix de Diane'' winner (Mondaine), etc...
