During World War II, Abadan was a major logistics center for Lend-Lease aircraft being sent to the Soviet Union by the United States.
In 1951, Iran nationalized all oil properties and refining ground to a stop on the island. Rioting broke out in Abadan, after the government had decided to nationalize the oil facilities, and 3 British workers were killed. It wasn't until 1954, that a settlement was reached, which allows a group of international oil companies to manage the production and refining on the island. This continued until 1973, when the NIOC took over all facilities. After total nationalization, Iran focused on supplying oil domestically and built a pipeline from Abadan to Tehran.
Whereas Abadan was not a major cultural or religious center, it did play an important role in the Islamic Revolution. On 19 August 1978—the anniversary of the US backed pro-Shah coup d'état which overthrew the nationalists and popular Iranian prime minister, Dr. Mohammed Mossadegh— the Cinema Rex, a movie theatre in Abadan, Iran, was set ablaze. The Cinema Rex Fire was the site of 430 deaths, but more importantly, it was another event that kept the Islamic Revolution moving ahead. At the time there was a lot of confusion and misinformation about the incident; however the public blamed the local police chief and also the Shah and SAVAK. The reformist Sobhe Emrooz newspaper in one of its editorials revealed that the Cinema Rex was burned down by the radical Islamists. The newspaper was shut down immediately after.[citation needed] Over time, the true culprits, radical Islamists, were apprehended and the logic behind this act was revealed, as they were trying both to foment the general public to distrust the government even more, and also as they perceived cinema as a link to the Americans. This fire was one of four during a short period in August, with other fires in Mashhad, Rizaiya, and Shiraz.
