A mare is an adult female horse or other equine.

In most cases, a mare is a female horse over the age of three, and a filly is a female horse age three and younger. However, in Thoroughbred horse racing, a mare is defined as a female horse more than four years old. The word can also be used for other female equine animals, particularly mules and zebras, though a female donkey is usually called a "jenny." A broodmare is a mare used for breeding. A horse's female parent is known as its dam.

An adult male horse is called a stallion, or, if castrated, a gelding. Occasionally the term "horse" is used in a restrictive sense to designate only a male horse.

Mares carry their young, called foals, for approximately 11 months from conception to birth. (Average range 320–370 days.) Usually just one young is born; twins are rare. When a domesticated mare foals, she nurses the foal for at least four to six months before it is weaned, though mares in the wild may allow a foal to nurse for up to a year.

The estrous cycle, also known as "season" or "heat" of a mare occurs roughly every 19–22 days and occurs from early spring into autumn. As the days shorten, most mares enter an anestrus period during the winter and thus do not cycle in this period. The reproductive cycle in a mare is controlled by the photoperiod (length of the day), the cycle first triggered when the days begin to lengthen. As the days shorten, the mare returns to the anestrus period when she is not sexually receptive. Anestrus prevents the mare from conceiving in the winter months, as that would result in her foaling during the harshest part of the year, a time when it would be most difficult for the foal to survive.

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.
