Lech Walesa was born on September 29, 1943. The first mention of Walesa's dissident activity goes back to 1968, when he have encouraged his fellow workers in the Shipyard to boycott official rallies condemning students' strikes. From that time he started to be increasingly active in social matters. After the tragic developments of the 1970 strike, which ended in the death of 39 workers, he swore that he would never allow for such situation to happen again. He was one of the main instigators of the August protest in 1980.
