Ladislaus IV of Hungary and Rudolf I of Germany defeat Ottokar II of Bohemia in the Battle on the Marchfeld near Dürnkrut in (then) Moravia.

Ladislaus IV, also known as Ladislaus the Cuman, was King of Hungary and Croatia from 1272 to 1290. His mother, Elizabeth, was the daughter of a chieftain from the pagan Cumans who had settled in Hungary. At the age of seven, he married Elisabeth, a daughter of King Charles I of Sicily. Ladislaus was only 9 when a rebellious lord, Joachim Gutkeled, kidnapped and imprisoned him.

Rudolf I was the first King of Germany of the Habsburg dynasty from 1273 until his death.

Ottokar II, the Iron and Golden King, was a member of the Přemyslid dynasty who reigned as King of Bohemia from 1253 until his death in 1278. He also held the titles of Margrave of Moravia from 1247, Duke of Austria from 1251, and Duke of Styria from 1260, as well as Duke of Carinthia and landgrave of Carniola from 1269.

The Battle on the Marchfeld at Dürnkrut and Jedenspeigen took place on 26 August 1278 and was a decisive event for the history of Central Europe for the following centuries. The opponents were a Bohemian (Czech) army led by the Přemyslid king Ottokar II of Bohemia and the German army under the German king Rudolph I of Habsburg in alliance with King Ladislaus IV of Hungary. With 15,300 mounted troops, it was one of the largest cavalry battles in Central Europe during the Middle Ages. The Hungarian cavalry played a significant role in the outcome of the battle.
