Democracy may be a word familiar to most, but it is a concept still misunderstood and misused in a time when totalitarian regimes and military dictatorships alike have attempted to claim popular support by pinning democratic labels upon themselves. Yet the power of the democratic idea has also evoked some of history's most profound and moving expressions of human will and intellect: from Pericles in ancient Athens to Vaclav Havel in the modern Czech Republic, from Thomas Jefferson's Declaration of Independence in 1776 to Andrei Sakharov's last speeches in 1989.
