Before the Second World War, the voting age in almost all countries was 21 years or higher. Czechoslovakia was the first to reduce the voting age to 20 years in 1946, and by 1968 a total of 17 countries had lowered their voting age. Many countries, particularly in Western Europe, reduced their voting ages to 18 years during the 1970s, starting with the United Kingdom (1970), with the United States (26th Amendment) (1971), Canada, Germany (1972), Australia (1974), France (1974) and others following soon afterwards. By the end of the 20th century, 18 had become by far the most common voting age. However, a few countries maintain a voting age of 20 years or higher. It was argued that 18-year-old men could be drafted to go to war, and many people felt they should be able to vote at the age of 18.

So, the answer is 1971.
