Lech Wałęsa
Lech Wałęsa led the August 1980 shipyard strike that produced Solidarity, the first independent trade union recognised in a Warsaw Pact state, surviving martial law and imprisonment before receiving the 1983 Nobel Peace Prize and becoming Poland's first freely elected president in 1990. Documents surfacing between 2008 and 2017, including files seized from a deceased interior minister's home, allege he collaborated with Polish security services as an informant in the early 1970s, a claim he denies and that remains genuinely disputed among historians examining the same evidence.
