1990 (MCMXC) was a common year starting on Monday of the Gregorian calendar, the 1990th year of the Common Era (CE) and Anno Domini (AD) designations, the 990th year of the 2nd millennium, the 90th year of the 20th century, and the 1st year of the 1990s decade.
Important events of 1990 include the Reunification of Germany and the unification of Yemen, the formal beginning of the Human Genome Project (finished in 2003), the launch of the Hubble Space Telescope, the separation of Namibia from South Africa, and the Baltic states declaring independence from the Soviet Union amidst Perestroika. Yugoslavia's communist regime collapses amidst increasing internal tensions and multiparty elections held within its constituent republics result in separatist governments being elected in most of the republics marking the beginning of the breakup of Yugoslavia. Also in this year began the crisis that would lead to the Gulf War in 1991 following the Iraq invasion and the largely internationally unrecognized annexation of Kuwait. This annexation resulted in a crisis in the Persian Gulf involving the issue of the sovereignty of Kuwait and fears by Saudi Arabia over Iraqi aggression against their oil fields near Kuwait. This led to Operation Desert Shield being enacted with an international coalition of military forces being built up on the Kuwaiti-Saudi border with demands for Iraq to peacefully withdraw from Kuwait. Also in this year, Nelson Mandela was released from prison, and Margaret Thatcher resigned as Prime Minister of the United Kingdom after more than 11 years.
