Below I list the female chess worldchampions.
1. 1927-1944 Vera Francevna Menchik (1906-1944) from Czechoslovakia/England.
Born in Moscow, daughter of a Czech father and an English mother. At the age of nine she learned chess and as a teenager moved with her family to London, where she took chess lessons from Geza Maroczy (Hungarian, 1870-1951), at the time one of the top-10 players in the world. Vera Menchik was easily the strongest female player of her time, having at one time or other beaten most of the strongest players in the world (the defeated became members of the “Vera Menchik Club“). In 1927 she won the first Women’s World Championship tournament with a score of 10.5 out of 11. She defended her title with ease in Hamburg 1930, Prague 1931, Folkestone 1933, Warsaw 1935, Stockholm 1937 and Buenos Aires 1939. Menchik met a tragic death in June 1944. She was killed with her mother and chess-playing sister during one of the last German air attacks on London.

3. 1950-1953 Liudmila Rudenko (1904-1986) from the Soviet Union.
Ludmila Rudenko from Byelorussian started her career by winning the women’s champion of Moscow in 1928. She went on to win the Women’s World Championship tournament in 1949, with a score of 11.5 out of 15. She held the title until 1953.

4. 1953-1956 Elizaveta Bykova (1913-1989) from the Soviet Union.
Elizaveta Bykova was coincidentally born in a town called Bogolyubovo in Russia. In 1938 she became women’s champion of Moscow, which she subsequently won a number of times. She was first the USSR Championships of 1947, 1948 and 1950. The first Candidates Tournament for women was held at Moscow in 1952. Elizaveta Bikova won the event (+11-3=1), one point ahead of 2nd/3rd places, earning the right to face Rudenko in the first modern Women’s World Championship match. Behind by one point in the last game, Rudenko needed a win to retain the title. She fought hard, but lost. Elizaveta Bikova thus beat Rudenko (+7-5=2) to become the second women’s World Champion.

5. 1956-1958 Olga Rubtsova (1909-1994) from the Soviet Union.
At 17 Olga won the first USSR Women’s Championship. That was in 1927. After that she won a great number of tournaments, including the USSR Women’s Championships of 1931, 1937 and 1949 and the Moscow Championships of 1953 and 1954. The second Candidates Tournament, Moscow 1955, was won by Rubtsova (+13-2=4), one-half point ahead of 2nd place. FIDE decided that the World Championship would be a triangular match of the three strongest players in the world. Olga Rubtsova won at Moscow in 1956, one-half point ahead of Bikova who finished five points of Rudenko.

6. 1958-1962 Elizaveta Bykova (1913-1989) from the Soviet Union.
With no intervening Candidates event, Bikova regained the title at Moscow in 1958, beating Rubtsova (+7-4=3). She accomplished the first successful defense of the title by beating Kira Zvorikina, winner of the Candidates Tournament, with a score of +6-2=5 at Moscow in 1959. In that same year she also won an International Tournament in Amsterdam.
7. 1962-1978 Nona Gaprindashvili (1941- ) from the Soviet Union.
She was born in Tbilisi, Georgia, and was the greatest female player of her generation. She won the fourth Candidates Tournament, Vrnjacka Banja 1961, (+10-0=6) two points ahead of 2nd place. Gaprindashvili crushed Bikova (+7-0=4) in the title match, Moscow 1962, to become the fourth Women’s World Champion. Gaprindashvili defended her title against Alla Kushnir of Russia in matches at Riga 1965 (+7-3=3), Tbilisi/Moscow 1969 (+7-2=5), and Riga 1972 (+5-4=7). Her last successful title defense (+8-3=1) was against her compatriot Nana Alexandria of Georgia at Pitsounda/Tbilisi 1975. Gaprindashvili played in men’s tournaments, winning amongst others Hastings 1963/64 and and tied for first at Lone Pine 1977. In 1978 she came second and earned a full male GM title.

8. 1978-1991 Maia Chiburdanidze (1961- ) from the Soviet Union.
The Georgian was one of the first women chess prodigies, becoming the youngest WIM in the history of the game (in 1974 at the age of 13). The 1976-78 cycle saw two Interzonals at Roosendaal and Tbilisi. Chiburdanidze finished second at Tbilisi behind Elena Fatalibekova, the daughter of Olga Rubtsova, third World Champion. Fatalibekova was eliminated in a semifinal Candidates match by Kushnir, but Chiburdanidze beat Alexandria (+3-2=5), Elena Akhmilovskaya (+4-3=5), and Kushnir (+4-3=7) to earn the right to challenge Gaprindashvili. When 17-year old Maia Chiburdanidze beat Gaprindashvili (+4-2=9) at Tbilisi in 1978, the torch passed from one generation of Georgian women champions to the next. She defended her title against Alexandria at Borsomi/Tbilisi 1981 (+4-4=8), Irina Levitina at Volgograd 1984 (+5-2=6), Akhmilovskaya at Sofia 1986 (+4-1=9), and Nana Ioseliani at Telavi 1988 (+3-2=11).

9. 1991-1996 Xie Jun (1970- ) from China.
Xie Jun became junior Xiangqi (Chinese chess) champion of Beijing at the age of six. She was later persuaded to take up chess. The Georgian domination of women’s international chess ended abruptly at Manila 1991, when the young Chinese star Xie Jun beat Chiburdanidze (+4-2=9). She had earned the right to be challenger by finishing second behind Gaprindashvili at the 1990 Interzonal in Kuala Lumpur, tying with Alisa Maric at the Candidates Tournament, Borzomi 1990, then beating Maric (+3-1=3) in a tiebreak match.

10. 1996-1999 Susan Polgar (1969- ) from Hungary.
The oldest of the famous Polgar sisters initially refused to play in women’s tournaments, becoming a male grandmaster in 1991 at the age of 23. In 1993 she decided to play for the women’s world championship, but did not win the title after a 12-12 draw against Nana Ioseliani. The next cycle was all Susan Polgar’s. After tying with Chiburdanidze in the Candidates Tournament, Tilburg 1994, she beat the ex-World Champion in the final match (+4-0=3), St. Petersburg 1995. She went on to beat Xie Jun (+6-2=5) at Jaen 1996, giving the Polgar family its first World Champion. Susan has also won the Women’s World Chess Champion titles in rapid and blitz chess (both in 1992).

11. 1999-2001 Xie Jun (1970- ) from China.
In the summer of 1994 Xie Jun was awarded the full Grandmaster title. The final match in the Women’s Championship was scheduled to be played in Shenyang, after sponsors from China made the best offer for the prize fund. Galliamova refused to play the entire match in China and the win was awarded by default to Xie Jun. The title match would be Polgar – Xie Jun II. By the time FIDE announced the date and venue for the title match, Polgar had given birth to her first child. She considered that the time to recover from childbirth and to prepare for the new match was insufficient. She requested that the match be postponed, FIDE refused, and negotiations broke down. After the contract deadline passed, FIDE declared that the title match would be played between Xie Jun and Galliamova. The forfeited Candidates match was to be resurrected as a title match! The 1999 match, with a venue split between Kazan and Shenyang, was won by Xie Jun (+5-3=7). A year later, at New Delhi 2000, Xie Jun defended her title by winning the first Women’s Championship played with the knockout format. She beat her compatriot Qin Kanying (+1-0=3) in the final match of the six round event. Xie Jun is one of three women to have at least two separate reigns, besides Elisaveta Bykova and Hou Yifan.
