The famous Gettysburg Address given by US President Lincoln in 1863 begins with the words "Four score and seven years ago." How many years is that?
"Four score and seven years ago" is 87 years since one score is 20 years. It referred to the start of the American Revolution in 1776.
One of the most poignant and powerful speeches in the history of the US was given by Abraham Lincoln on the 19th of November, 1863. It was the time of the American Civil War. This famous speech was delivered at the dedication of the Soldiers' National Cemetery in Gettysburg, Pennsylvania, four and a half months after the Battle of Gettysburg. It took Lincoln only 2 minutes to reiterate the main ideas of equality espoused by the Declaration of Independence. He also proclaimed the Civil War as a struggle for the preservation of the Union.
