Fidel Castro resigns
Fidel Castro ruled Cuba unchallenged for nearly half a century.
He was hated by the United States -- whose secret service more than once tried to assassinate him -- and was at the center of the Cuban missile crisis which brought the US and the Soviet Union to the very brink of nuclear war.
The world held its breath for 12 unbearably tense days in October 1962 after President John F. Kennedy discovered that Kremlin leader Nikita Khruschev was placing nuclear missile installations on the island.
The crisis -- probably the most perilous time of the entire Cold War -- was abated only when Khruschev backed down and said the installations would be dismantled.
When Castro, and his Marxist revolutionary friends, seized power in 1959, he proceeded to nationalize all US property, leading to relentless hostility towards him from the United States.
The CIA tried all manner of ways to assassinate him, including a bizarre exploding cigar, designed to detonate when Castro puffed on it, and booby-trapped seashells in spots where he used to enjoy diving.
In 1961, the US tried to invade Cuba at the Bay of Pigs, but the Cubans successfully fought them off.
Meanwhile, the Cuban economy was being propped up by the Soviet Union -- a further source of friction between Cuba and the United States -- with the Kremlin purchasing vast amounts of sugar and supplying Castro with economic and military aid.
But the collapse of communism and the destruction of the Soviet Union reduced Cuba to a dire economic state and left Castro a diminished international figure.
Even so, he remained unchallenged. But in July 2006, ill health caused him to delegate virtually all his duties to his brother, Raul Castro. This transfer was supposed to be temporary while Fidel recovered from surgery for "an acute intestinal crisis with sustained bleeding."
By then, Fidel was physically frail and infirm. And on Feb. 19, Castro officially resigned after 49 years as Cuba's leader.
Fidel Castro was born on Aug. 13, 1926, attending Catholic schools before graduating from the University of Havana with a degree in law. Two years later, he ran for election to the Cuban House of Representatives, but the elections were halted by the then dictator Fulgencio Batista.
As a result, an enraged Castro assembled a small force and attacked the Moncada army barracks in Santiago de Cuba in 1953. It failed and most of his supporters were killed or captured. Castro was himself captured and sentenced to 15 years in prison, but he was pardoned after just two years.
It was during his trial that Castro delivered his famous "History will absolve me" speech.
In it he said: "I warn you, I am just beginning! If there is in your hearts a vestige of love for your country, love for humanity, love for justice, listen carefully.
"I know that the regime will try to suppress the truth by all possible means. I know that there will be a conspiracy to bury me in oblivion. But my voice will not be stifled -- it will rise from my breast even when I feel most alone, and my heart will give it all the fire that callous cowards deny it.
"Condemn me. It does not matter. History will absolve me."
Castro went into exile in Mexico where he trained a group of revolutionaries called the 26th of July Movement. In December 1956, his forces, supported by Che Guevara and others, invaded Cuba from the ship Gramma, but suffered serious losses.
However, the revolutionaries hid in the Sierra Maestra mountains, gaining support among the peasants. Eventually, on Jan. 1, 1959, Batista fled the island and Castro assumed power.
Relations with the US declined rapidly. In 1960, Castro took over the US oil refineries in Cuba and the US stopped buying Cuban sugar. He responded by taking over all US businesses in Cuba, and a furious President Kennedy responded with his failed Bay of Pigs invasion attempt.
Various theories have been put forward for the failure of this operation. One was that Kennedy, at the last minute, mysteriously withdrew essential air support, and another was that the president had gravely under-estimated the scale of support for the Marxist Castro among the Cuban people.
Castro feared another US attack, and so when Khruschev offered to place nuclear missiles on the island, he agreed.
This brought Kennedy and Khruschev into face-to-face snarling conflict, until Khruschev backed down. Castro, who was no more than a pawn in this dangerous international conflict, felt let down by the USSR, which nevertheless continued to prop up the island's otherwise dire economy.
Despite this setback, and later the even more damaging effect of the collapse of the Soviet Union, Castro's omnipotence over Cuba remained undisputed.
Castro did much to improve education and health services and other social services on the island.
The various assassination attempts were straight from the pages of James Bond. These included an attempt to smuggle a jar of cold cream containing pills into his room, the exploding cigar, a fungal-infected scuba-diving suit and a Mafia-style shooting.
Some of these plots were depicted in a documentary entitled 638 Ways to Kill Castro. He once said in regard to the myriad of failed attempts on his life: "If surviving assassination attempts were an Olympic event, I would win a gold medal."
