: Uhry Imre Kovács- és Kocsigyártó Üzeme) and during the Communist era in Hungary it dominated bus markets of the entire Eastern Bloc and its allies.

After a number of expansions, in 1913 Uhry bought a new plant, and by the outbreak of World War I they started to focus on building and repairing truck superstructures.

For example, in 1934 the company's luxury autobus built on a Gräf & Stift chassis was presented on the French Concours d'Élégance car beauty contest.

[citation needed] The first metal-body autobus in Hungary was the Uhri Siblings' MÁVAG N26/36, which was followed by a successor with some modifications every year.

In 1948, like many other enterprises in the newly-established Second Hungarian Republic at the time, the company was nationalised and thus became property of the state, which was followed by the Uhri-family's departure from Hungary (who left out of fear from the newly-formed government backed by the Soviet Union).

[13] As a result of the war, there was shortage of chassis in Hungary, but at the same time there was a growing need for buses, as most of them were destroyed or severely damaged during the Siege of Budapest.

[16] During this short period, Ikarus had ambitious plans, as they designed two different bus models exclusively for export goals.

This model was called the M5 and was built on the same chassis as the Tr 5, but received a redesigned front, manually operated swing doors and somewhat more passenger seats.

[17] In 1951, after a long and heated argument between the engineers and the political decision makers on whether unibody or body-on-frame vehicles should be produced, the parties managed to reach a compromise.

Their engines were mounted in the rear section of the vehicles, which had a distinctive configuration and look, resulting in its common nickname Faros (roughly: Buttocks).

[25] In 1963, the Hungarian state decided to merge the Általános Mechanikai Gépgyár or ÁMG ("General Mechanical Machine Factory") with Ikarus.

[29] It was the designer, László Finta's idea to make the structure of the bus more angular, therefore creating more space along with better view for the passengers.

It also participated in a contest in Monaco, 1971, where the Ikarus 250 SL (luxury submodel) won Rainier III's grand trophy.

[31] From 1968 onwards, Ikarus started to develop and produce a variety of experimental vehicles, in order to find the correct configuration for future models within the family.

Although it was a well built model with the era's required technology, not many orders were received, because Ikarus' main market was in the Eastern Bloc, which just started to suffer economically.

[43] This Ikarus family of models was produced between 1979 and 1999 as the company's answer for the request of various developing countries, as they had a need for cheap, small and versatile vehicles.

Many companies sold their products to Ikarus, which then built superstructures on them, these include: Volkswagen, Avia, MAN, Renault and even Isuzu.

And the third issue was that in 1990, the Soviet Union was on the brink of bankruptcy; the Hungarian government's response to this was an immediate halt on exports to the USSR.

[47] In spite of the numerous setbacks, Ikarus managed to stay above water, partially thanks to some newly conquered markets such as the United Kingdom.

From 1990 to 2001, the company developed and exported three models exclusively for the UK, the last of which was designed in 2000, named the Ikarus 489 Polaris and was a very up-to-date, modern vehicle.

The Classic-series proved to be a success, since the Eastern and Hungarian customers were glad to buy the newer versions of the familiar models, while Ikarus also gained somewhat more income on producing them.

In 2003, the French majority ownership concluded that it couldn't acquire these markets and decided that after closing down the factory in Budapest, in 2000, it should end the whole company.

was founded, which company also registered the brand name on June 30, 2016, so not long after, a lawsuit to establish a trademark infringement and its legal consequences was started.

also distanced themselves, and in October it started liquidation of the company group, it did not fulfill its orders, there was also a problem with the previous prototypes (hybrid, electric, gas and trolley-driven composite type C Modulók).

[64] The Ikarus 120e was presented at the Greentech 2021 sustainability trade show, the first purely electric bus designed and manufactured in Hungary with European type approval.

[65] Two important elements of the model come from China: the battery (manufactured by CATL) and the drive system (the work of the large corporation CRRC).

[64][66][67] This part of Ikarus' history starts in 1967, when the company decided to establish a smaller plant, where the unique or small numbered models could be developed and produced.

[68] The Ikarus' model proved to be prominent, which resulted in several orders from German operators, and a total of 256 units' export until 1977.

[69] Later on, from 1976, Sweden also started to be curious about the Ikarus models, so they ordered a small number of them, with major modifications to fit the VöV-regulations' Swedish counterparts, the STLF-, or Svenskkollektivtrafik-regulations.

The EAG started to develop its own, higher-quality coaches and buses on chassis called the E-series and became a considerable exporter primarily to the Scandinavian and Western markets.
