The Sassanid Persian Empire (pronounced /ˈsæsənɪd/; also spelled Sasanid Empire, Sassanian Empire, or Sasanian Empire), known to its inhabitants as Ērānshahr and Ērān in Middle Persian and resulting in the New Persian terms Iranshahr and Iran, was the last pre-Islamic Persian Empire, ruled by the Sasanian Dynasty from AD 224 to AD 651. The Sassanid Empire, which succeeded the Parthian Empire, was recognized as one of the two main powers in Western Asia and Europe, alongside the Roman Empire and the Byzantine Empire, for a period of more than 400 years.

The Sassanid Empire was founded by Ardashir I, after the fall of the Arsacid Empire and the defeat of the last Arsacid king, Artabanus IV. During its existence, the Sassanid Empire encompassed all of today's Iraq, Iran, Afghanistan, eastern Syria, the Caucasus (Armenia, Georgia, Azerbaijan, and Dagestan), southwestern Central Asia, part of Turkey, certain coastal parts of the Arabian Peninsula, the Persian Gulf area, and areas of southwestern Pakistan. The native name for the Sassanid Empire in Middle Persian is Eran Shahr which means Aryan Empire. According to legend, the vexilloid of the Sassanid Empire was the Derafsh Kaviani. It was also hypothesized that the transition toward the Sassanid Empire represents the end of struggle of ethnic proto-Persians with their close migrant ethnic relatives, the Parthians, whose original homeland was in modern-day Central Asia.

The Persian Gulf War (2 August 1990 – 28 February 1991), codenamed Operation Desert Storm (17 January 1991 – 28 February 1991) commonly referred to as simply the Gulf War, was a war waged by a UN-authorized coalition force from 34 nations led by the United States, against Iraq in response to Iraq's invasion and annexation of Kuwait.

The war is also known under other names, such as the First Gulf War, Gulf War I, or the Iraq War, before the term "Iraq War" became identified instead with the 2003 Iraq War (also referred to in the U.S. as "Operation Iraqi Freedom").

The invasion of Kuwait by Iraqi troops that began 2 August 1990 was met with international condemnation, and brought immediate economic sanctions against Iraq by members of the UN Security Council. U.S. President George H. W. Bush deployed American forces into Saudi Arabia, and urged other countries to send their own forces to the scene. An array of nations joined the coalition. The great majority of the military forces in the coalition were from the United States, with Saudi Arabia, the United Kingdom and Egypt as leading contributors, in that order. Around US$36 billion of the US$60 billion cost was paid by Saudi Arabia.
