[EX Q]: Question: How long had the Algerian war been going on when Kopanski was 14? Passage:In 1962, when only 14, he was fascinated by the success of the Arab national and anti-colonial forces that defeated the French colonial armies in the Algerian War, gaining independence for their country. When attending a military college in Kętrzyn (Ger. Rastenburg) in 1966-1969, he actively opposed the Polish communist regime during the 1968 Polish political crisis, and as a result was expelled from the Officer School, and became a political prisoner for the first time. He continued his studies at the University of Silesia in Katowice, and after graduation was employed there as a lecturer,adiunct and researcher. In 1980-81, when Poland was swept by a wave of anti-communist strikes, and around ten million joined the anti-communist Solidarity trade union, Kopański co-founded a branch of this broad grassroots social movement at the University of Silesia.
