In Serbian, the village is known as Kruševlje or Крушевље, in German as Kruschiwel or Kruschiwl, and in Hungarian as Körtés or Bácskörtés.

The whole area surrounding Kruševlje is a flat ground, with many swampy meadows, fens, bad-fruitful salt-spring fields.

The earliest appearance of this settlement is recorded by Hungarians in 1520 as Körtvélyes, and again in 1598 as Kruševlje in some Turkish lists, but it is certainly evident that it existed even earlier.

During the Late Middle Ages (14th-16th century) it was populated with Serb nomads and cattle-breeders, many of whom lived there only temporarily and built a few small wooden-or mudd-cottages and huts.

During the Ottoman rule (1541–1687) the village of Kruševlje was populated by ethnic Serbs and the nearest Turkish stronghold was in Sombor, about 12 miles to the south, but living there was very hardly and dangerously, because the Turks were very cruel and ruthless to all those who did not or could not pay all the taxes, that they demanded.

All the Hungarian and a lot of Serb population of all southern parts of the Pannonian Plain that were administered by the Kingdom of Hungary fled to the north before the Turks arrived and Kruševlje was also deserted by the time.

It was resettled by a dozen or so Serb cattle-breeders, but they again had to flee in 1598 when the whole area was devastated by the Tatar forces, arriving there as Turkish vassals.

It was then, in 1598 that the village of Kruševlje is recorded for the first time, mentioning its inhabitants as Turkish serfs and tenantfarmers who fled with their village-leader named Mihajlo to the town of Esztergom in the northern part of Hungary.

The Turks were banished from most of the Pannonian Plain during the Great Turkish War (1683–1699), and Kruševlje itself came under Habsburg rule with the complete Bačka area in September 1687 by the victorious troops under the Imperial Prince Eugene of Savoy.

In the early 18th century Kruševlje was again abandoned, and later mentioned in 1740 as a part of county named Somborski Šanac (English: The Trench of Sombor).

The new page in the history of Kruševlje came with the colonization of southern Pannonian Plain administered by the Habsburg Monarchy.

The majority of those colonist families came on floats called Ulmer Schachtel by the river Danube travelling about two or three weeks from the German Imperial town of Ulm, where they were called to gather mostly from the Imperial estates in Lorraine, Alsace, Rhineland, and the Electorate of the Palatinate (German: Pfalz).

There were also some families who came from other parts of Southwest Germany, mostly from County of Baden, Württemberg, Bavaria, Swabia, Bohemia and Moravia, as well as from some decades earlier established colonist villages in Hungary administered by the Habsburg Monarchy, like in the Counties of Tolna, Pest, Buda and Baranya.

In later years (especially in the 1780s and in the early 19th century) more Swabian families moved to Kruševlje from the neighbouring villages of Gakovo, Kolut, Csátalja, Gara, Katymár, etc., but it remained a mostly conservative society.

During the 1760s and the 1770s the Kruševlje people built their new village in their own German style: long, wide main street, called in German: Die Kirchengasse or die Hauptgasse, three short Kreuzgassen, and long, but narrow family houses, always whitewashed, including two rooms, a kitchen, a stable (stall) and a shed.

After him, as the Kruševlje teachers served Jakob Kirstner, Simon Scheidler, Ferdinand Klemm, and from 1888 Franz Schamberger.

Many families from Kruševlje possessed their fields and vineyards to the north, towards Riđica, because all the other land parts were pasture-grounds, grassland, fens, or saltfields unsuitable for cultivation and tillage.

Kruševlje was electrified in 1925 from Stanišić, had a steam-mill, a library, a four-class primary school, a nursery-garden, a silk-manufactory and was a fairly prosperous community.

During World War I more than 250 men from Kruševlje participated as soldiers in Austro-Hungarian army, and more than 150 were killed or wounded, mostly in Galicia on the Eastern front.

In 1918, the village occupied by the newly formed Kingdom of Serbs, Croats and Slovenes, called Yugoslavia since 1929.

The Germans founded their cultural society called later Kulturbund and during the 1930s some minor families were sympathising the Nazi Party.

The villagers also sent some aid in food and clothes to the Eastern front and Germany, and there was no other role in the war campaign.

As empty villages in 1948, Kruševlje and Gakovo were repopulated with Greek and Macedonian refugees of the Civil war in Greece which ended in 1946.

They were all communist families and were settled down in former German-populated village of Maglić in Bačka, but were resettled to Gakovo and Kruševlje in 1948 and 1949.
