Foeni was first mentioned in 1289, under the name Föen, on the occasion of the convocation here of a diet by King Ladislaus III.^[4] Attested by the Ravenna Geographer, the Roman castrum of Bacaucis lied on Foeni's present-day hearth, on the road from Tibiscum to Lederata.^[5] The first to do systematic research was Augustin Bárány, in 1845, after a large number of objects and bricks with Roman seals were found in the area.^[6] In 1890, Francisc Cumont makes a scientific description of the results of Bárány's research and concludes that in the garden of Mocioni Mansion and near it is the foundation of the Roman castrum. At the same time, epigraphic monument, coins, vessels, etc. were discovered. In 934, in Foeni, in the place called Vadum Arenarum, near the Timiș River, a battle between the Hungarian invaders and the reunited troops of the Pechenegs, Romanians and Bulgarians led by Duke Glad took place.^[7] The battle ended with Glad's defeat, who then had to prepare a new resistance at Kevea (probably Kovin, Serbia) and then at Orșova. Although he lost the battles, Glad and his successors continued to lead the duchy until 1003–1004 when Glad's dynasty was replaced by Chanadinus.^[7]

At the beginning of the 18th century, after the conquest of the area by the Austrians, due to the conflict, only 18 houses remained in Foeni.^[2] In the same century, towards the end of it, the Mocioni family appears in the area.^[8] They established their residence in Foeni, where in 1750 they built a Neoclassical mansion here.^[9]

Cruceni was originally located in the "Place of the Cross" (Romanian: Locul crucii), a few kilometers from the current village, towards Timiș River.^[2] The present-day Cruceni was created by German colonization in 1722,^[2] being designed according to the same Austrian models adapted to Banat, with straight and perpendicular streets. The first church, a Roman Catholic one, was built in 1780. The new church was built in 1914. After the establishment of the Austro-Hungarian dualism in 1868, the first Hungarian families of tobacco growers began to come to Cruceni. 75 families settle here at that time, to whom a plot of land with one juger of built-up land and seven jugers of arable land is distributed. Towards the end of the 19th century, the village became predominantly Hungarian, while Germans moved to other localities.

Foeni and Cruceni were severely affected by the April 2005 floods that saw 90% of homes flooded and 1,100 people displaced.^[10]
