After World War II and the beginning of communism in 1948 the club descended to the lower leagues and they didn't rejoin the top flight until 1993.

After finishing mid-table in their first season back in the top flight, in 2009 they were relegated back to the second league after struggling all season, with one of the only highlights being Petr Švancara winning Czech Television's goal of 2008 (gol roku), with his stunning individual effort to open the scoring in Žižkov's 4–2 home victory against FK Bohemians Prague (Střížkov).

Their season started with just seven points from the opening 14 rounds of the 2011–12 Czech First League, resulting in the club parting company with coach Martin Pulpit on 23 November.

The very popular 1931 Czech comedy film Muži v offsidu is centered largely on the culture and fans of Viktoria Žižkov and features unique footage of several matches from that time.

The Czech film actor Vlasta Burian played as the regular goalkeeper for Žižkov around 1916 before setting out on his acting career.
