It was the final year of the Cold War, which had begun in 1947. Towards the end of the year, the Soviet Union collapsed, leaving fifteen sovereign republics and the CIS in its place.

This increased GDP but also increased income inequality over the next two decades. A UN-authorized coalition force from 34 nations fought against Iraq, which had invaded and annexed Kuwait in the previous year, 1990. The conflict would be called the Gulf War and would mark the beginning of a since-constant American military presence in the Middle East.
