Among his many honors were Sweden's prestigious Olof Palme Prize and the Presidential Medal of Freedom, the highest U.S. civilian award, bestowed on him by President George W. Bush for being "one of liberty's great heroes."
An avowed peacenik whose heroes included rockers such as Frank Zappa, he never quite shed his flower-child past and often signed his name with a small heart as a flourish.
"Truth and love must prevail over lies and hatred," Havel famously said. It became his revolutionary motto which he said he always strove to live by.
"It's interesting that I had an adventurous life, even though I am not an adventurer by nature. It was fate and history that caused my life to be adventurous rather than me as someone who seeks adventure," he once told Czech radio, in a typically modest comment.
Havel first made a name for himself after the 1968 Soviet-led invasion that crushed the Prague Spring reforms of Alexander Dubcek and other liberally minded communists in what was then Czechoslovakia.
Havel's plays were banned as hard-liners installed by Moscow snuffed out every whiff of rebellion. But he continued to write, producing a series of underground essays that stand with the work of Soviet dissident Andrei Sakharov as the most incisive and eloquent analyses of what communism did to society and the individual.
One of his best-known essays, "The Power and the Powerless" written in 1978, borrowed slyly from the immortal opening line of the mid-19th century Communist Manifesto, writing: "A specter is haunting eastern Europe: the specter of what in the West is called 'dissent.'"
