History
The plain was home to steppe peoples long before the Magyars: Sarmatians, Huns, Avars and Gepids all left graves here, and the Magyars themselves settled its grasslands in the 890s. In the 13th century King Béla IV invited Cuman and Jász (Alan) nomads to settle, and their names survive in the districts of Kunság and Jászság, where the relic known as Lehel's horn is kept at Jászberény.
The Ottoman conquest devastated the plain. Villages were burned and emptied, and people crowded into a few large market towns such as Debrecen and Kecskemét, which paid tribute to several masters and grew rich on cattle driven west to Vienna and beyond. Around 1605 the prince Stephen Bocskai settled his hajdú soldiers, former herdsmen, in free towns around Debrecen, giving Hajdú-Bihar its name. Debrecen became the centre of Hungarian Calvinism, and in 1849 Kossuth declared the Habsburgs dethroned in its Great Reformed Church.
In the 19th century the Tisza and its tributaries were regulated and marshes drained, turning pasture into farmland, and scattered farmsteads called tanya spread across the plain. Szeged was destroyed by a Tisza flood in 1879 and rebuilt with ring boulevards and new public buildings. The 1920 Trianon border cut the region's eastern cities off from their hinterlands now in Romania. Collectivisation after 1945 reshaped village life again, and Debrecen briefly hosted a provisional national government in 1944–45.
