[2] In antiquity, the river was known as Tibiscus (in Latin) and Tibisis (Θίβισις in ancient Greek), and as Timisis in De Administrando Imperio;[3] in addition, Edward Gibbon referred to it as the Teyss.

The Romans, who traversed the plains of Hungary, suppose that they passed several navigable rivers, either in canoes or portable boats; but there is reason to suspect that the winding stream of the Teyss, or Tibiscus, might present itself in different places under different names.

[7] In June 2023, Serbian government began process of declaring a landscape of outstanding features Potamišje ("Tamiš valley").

A spatial plan for wider valley area (including Sečanj and Plandište) has been concurrently made.

[8] Within the scopes of the Interreg IPA program, conducted jointly by Romania and Serbia, the area around the river has been arranged in the 2017-2019 period.

Starting from Timiș' origin in Romania, up to its mouth in Serbia, the bird watch towers, benches, gazebos, small bridges, billboards, signposts and waste containers have been placed.

Section between the bridge and old shipyard facilities will be completely reconstructed with addition of renovation of "city pontoon" (floating platform for various public activities), sports and recreation fields, skate park, ski slopes, bicycle paths, etc.

A small bridge was placed, and the crushed stone was poured before the beach, to purify and clear the water.

The grain was transported to the capital Vienna, while later, with the industrialization of Pančevo, shipping of the beer, silk, salt, bricks and timber developed.

With the appearance of the steam power, the passenger transport developed too, connecting Pančevo and Serbian capital Belgrade.

As Pančevo grew into the developed industrial center, by the early 20th century the traffic on Timiș became so intensive that the river had to be rerouted and straighten, with numerous canals being cut through around it.

[11] After the works to improve the navigation were conducted in the early 20th century, river's mouth area was left without any landmarks.

The trees and overgrowth were cut during the digging of the canals so the area and the course of the river was new and unfamiliar to the ship crews.

The one on the right bank of the Timiș is built in the Ferland locality, while the left one is in the Pančevo's section of Mali Rit.

The honking of the ships passing next to them was considered "obligatory", while the young boatmen and town youth used to visit and climb onto them, as a sort of the adolescent dare games.

It was a pentagon shaped structure built for artillery warfare., with brick-layered bastions, triangular ramparts, and a pontoon bridge across the Timiș.

[13] The river's old mouth into the Danube was some 40 km (25 mi) to the north-west, between villages of Čenta and Surduk, thus it was shorter.

Many meandering canals and bogs remained in the marsh: slow streams of Vizelj, Dunavac, Sibnica, Butuš, Rogoznica, Buk, Belanoš and Sebeš, and large bogs of Reva, Veliko Blato (2 km2 (0.77 sq mi)), Sebeš and Široka Bara.

After being almost uninhabited before 1945, today its population density is above average for Serbia as a whole, since some of the fastest growing suburbs of Belgrade (Borča, Padinska Skela and Krnjača) are built there.
