For most of the 1990s, Bill Clinton was president, the first baby boomer to live in the White House as the commander-in-chief. The Berlin Wall, the prime symbol of the Cold War, fell in November 1989, and Germany was reunited in 1990 after 45 years of separation. The Cold War officially ended with the fall of the Soviet Union on Christmas Day 1991, and it seemed as if a new era had dawned. The '90s witnessed the deaths of super celebrities Princess Diana and John F. Kennedy Jr. and the impeachment of Bill Clinton, which did not result in a conviction. In 1995, O.J. Simpson was found not guilty of the double murder of his ex-wife, Nicole Brown Simpson, and Ron Goldman in what's been called the trial of the century. The decade closed with the sun coming up on a new millennium on Jan. 1, 2000. 1:54 Watch Now: A Brief History of the 1990s 1990 Per-Anders Pettersson / Getty Images The '90s began with the biggest art theft in history at the Isabelle Stewart Gardner Museum in Boston.

The year went on to see the eruption of Mount Pinatubo in the Philippines that killed 800 and the airlift of 14,000 Jews from Ethiopia by Israel. Serial killer Jeffrey Dahmer was arrested, and South Africa repealed its apartheid laws. A Copper Age man was found frozen in a glacier, and on Christmas Day 1991, the Soviet Union collapsed, officially ending the Cold War that had begun in 1947, shortly after World War II ended in 1945. 1992 Corbis via Getty Images / Getty Images The year 1992 marked the beginning of the genocide in Bosnia and devastating riots in Los Angeles after the verdict in the Rodney King trial, in which three Los Angeles police officers were acquitted in the beating of King. 1993 Allan Tannenbaum/Getty Images In 1993, New York's World Trade Center was bombed and the compound of the Branch Davidian cult in Waco, Texas, was raided by agents from the Bureau of Alcohol, Tobacco, and Firearms. During the gun battle that followed, four agents and six cult members died. The ATF agents were trying to arrest the leader of the cult, David Karesh in connection with reports that the Davidians were stockpiling weapons. The lurid tale of Lorena Bobbitt was in the news, as well as the exponential growth of the internet. 1994 Corbis via Getty Images / Getty Images Nelson Mandela was elected president of South Africa in 1994 as genocide was occurring in another African nation, Rwanda. In Europe, the Channel Tunnel opened, connecting Britain and France. 1995 WireImage / Getty Images Many landmark events occurred in 1995. O.J.

There was a sarin gas attack in the Tokyo subway and Israeli Prime Minister Yitzhak Rabin was assassinated.

The tragic news: Britain's Princess Diana died in a car crash in Paris. 1998 David Hume Kennerly / Getty Images Here's what to remember from 1998: India and Pakistan both tested nuclear weapons, President Bill Clinton was impeached but escaped conviction, and Viagra hit the market. 1999 Brand New Images/Getty Images The euro made its debut as the European currency in 1999, the world was worried about the Y2K bug as the millennium turned, and Panama got the Panama Canal back.
