Born to a Ukrainian Jewish family, Zelenskyy grew up as a native Russian speaker in Kryvyi Rih, a major city of Dnipropetrovsk Oblast in central Ukraine. Before his acting career, he obtained a degree in law from the Kyiv National Economic University. He then pursued a comedy career and created the production company Kvartal 95, which produced films, cartoons, and TV shows including the TV series Servant of the People, in which Zelenskyy played a fictional Ukrainian president. The series aired from 2015 to 2019 and was immensely popular. A political party with the same name as the TV show was created in March 2018 by employees of Kvartal 95.
EDIT: Darn, someone else apparently mentioned it as well, checking their link. I’m still gonna leave this text up, though.
