Ilona Szabo was nicknamed Kócos and Kócoska (1939 - October 28, 1956), a Roma-born participant and martyr of the 1956 revolution.
Ilona Szabo was only 17 years old and 4 months pregnant when she became involved with revolutionary events with her friends. The young woman learned about the use of weapons between the Corvinian insurgents and became commander in command of six people in just a few days. On October 28, 1956, at the end of Práter Street, her partner Gábor Dilinkó fought in the Corvin area and was seriously injured and sentenced to 12 and 7 years imprisonment and finally released in 1966. Among the Roma warriors here, in Corvin, there were probably only two Gypsies, the other Gypsy fighters were among the Gypsy musicians, about 10 people.
During the Corvin, a plaque was erected in honor of Ilona Szabó.
