The Zimbabwe $1 Million Dollar Banknote was issued in 2008 during a period of hyperinflation. Hyperinflation in Zimbabwe was a period of currency instability that began in the late 1990's shortly after the confiscation of private farms from landowners, towards the end of Zimbabwean involvement in the Second Congo War. During the height of inflation from 2008 to 2009, it was difficult to measure Zimbabwe's hyperinflation because the government of Zimbabwe stopped filing official inflation statistics. However, Zimbabwe's peak month of inflation is estimated at 79.6 billion percent in mid-November 2008. In 2009, Zimbabwe stopped printing its currency, with currencies from other countries being used. In mid-2015, Zimbabwe announced plans to have completely switched to the United States dollar by the end of 2015. Over the course of the five-year span of hyperinflation, the inflation rate fluctuated greatly. At one point, the US Ambassador to Zimbabwe predicted that it would reach 1.5 million percent. In June 2008 the annual rate of price growth was 11.2 million percent. The worst of the inflation occurred in 2008, leading to the abandonment of the currency. The peak month of hyperinflation occurred in mid-November 2008 with a rate estimated at 79,600,000,000% per month.
