The New Martyrs of the Czech Lands are the clergy and laymen of the Orthodox Cathedral of Ss. Cyril and Methodius in Prague who were put to death by the Nazi occupiers in 1942 for sheltering the Czechoslovak parachutists who had assassinated the Deputy Reich-Protector Reinhard Heydrich. They are commemorated together on September 5, and their veneration is closely joined to that of their bishop, the Hieromartyr Gorazd (Pavlik) of Prague, who suffered with them.
The group canonized in this commemoration comprises the priests Vladimir Petrek and Vaclav Cikl, and the laymen Jan Sonnevend, who served as chairman of the cathedral's parish council, Vaclav Ornest, and Karel Louda. Several of their relatives also perished, including the wife and daughter of Jan Sonnevend and the wife of Father Cikl, who were deported to the Mauthausen concentration camp and killed. Beyond this immediate circle, the synaxarion accounts record that hundreds of Czechs connected to the parachutists were arrested in the same reprisals, with a number of the cathedral's congregation among those shot.
The events arose from Operation Anthropoid: on May 27, 1942, Czechoslovak parachutists trained abroad attacked and fatally wounded Reinhard Heydrich in Prague. Several of the men afterward took refuge in the crypt of the Orthodox cathedral, hidden with the knowledge and help of its clergy and faithful. After their location was betrayed, German forces surrounded the church on June 18, 1942; the soldiers in the crypt resisted until they were killed or took their own lives rather than be captured. The clergy and laymen who had given them shelter were arrested, interrogated, and brought to trial.
Following a trial in early September 1942, Bishop Gorazd, Father Cikl, and Jan Sonnevend were executed by firing squad on September 4, and Father Petrek was executed on September 5. The Orthodox Church of the Czech Lands and Slovakia, which had been suppressed and its activity banned in the aftermath, later honored these martyrs as witnesses of the faith. Bishop Gorazd was glorified in 1987, and his companions among the clergy, laity, and their families were formally canonized in 2020 as the Holy New Martyrs of Bohemia.
