 The fall of communism in the years between 1989 and 1991 led to a formal reestablishment of relations by the Polish and Lithuanian states.Poland was highly supportive of Lithuanian independence, and became one of the first countries to recognize independent Lithuania (on 26 August 1991).Despite that, there was a relative crisis in the early 1990s, due to alleged Lithuanian mistreatment of its Polish minority, and Lithuanian concerns that Poland sought again to put Lithuania under its sphere of influence, or even issue territorial claims.
