Poland has named 2014 the year of Jan Karski, a resistance fighter who was crucial in spurring allied intervention in World War II.

The Polish parliament voted unanimously last week to honor the Holocaust hero, in the year that would have seen his 100th birthday. Karski died in 2000.

Karski, a gentile, was born in Lodz and acted as a courier in the Polish underground during the Nazi regime. He consistently broke into the Warsaw Ghetto to pick up and relay information, details he would then share with the west.

He is credited as one of the first individuals to give witness accounts to the White House in an aim to encourage US assistance.

Karski penned a book about his efforts, “The Story of a Secret State,” which became a best seller. He was a Georgetown professor, and was named Righteous Among the Nations by Yad Vahsem in 1982. It is Israel’s highest designation.

Polish President Bronislaw Komorowski will act as honorary patron of the 2014 Karski year, which will include special events, conferences and educational programs.
