2003 invasion of Iraq

The 2003 invasion of Iraq, (from March 20 to May 1, 2003) was led by the United States, backed by British forces and smaller contingents from Australia, Denmark, Poland and Spain. Four countries participated with troops during the initial invasion phase, which lasted from March 20 to May 1. These were the United States (248,000), United Kingdom (45,000), Australia (2,000), and Poland (194). 36 other countries were involved in its aftermath. The invasion marked the beginning of the current Iraq War. In preparation for the invasion, 100,000 US troops were assembled in Kuwait by February 18.[15] The United States supplied the vast majority of the invading forces, but also received support from Kurdish troops in Iraqi Kurdistan.
