Since the creation of the Polish state and its Christianization, no Polish law, except during periods of occupation, has ever criminalized homosexuality. However, homosexuality has been a taboo subject for most of Poland's history, and that and the lack of legal discrimination have often led to a lack of historical sources on the subject. Homophobia has been a common public attitude in Poland because of the influence of Catholic Church in Polish public life and the widespread social conservatism in Poland. Homosexuality in Poland was decriminalized in 1932.
