Olympics in Tokyo, winning the overall title and taking gold medals in the balance beam and the vault, in addition to another silver medal in the team event. At the 1966 World Championships, Čáslavská defended her vault title, winning a team gold – breaking the Soviet monopoly in that event – and became all-around world champion. Čáslavská dominated the 1965 and 1967 European Championships, taking all five individual titles and scoring perfect scores of 10 in 1967. Prior to the 1968 Summer Olympics in Mexico City, Čáslavská lost her training facility due to the Soviet-led invasion of Czechoslovakia. Instead, she used potato sacks as weights and logs as beams whilst training in the forests of Moravia. She was again dominant at the 1968 Summer Olympics, winning medals in all six events. She defended her all-around title and won additional gold medals on the floor, uneven bars and vault, as well as two silvers, for the team competition and balance beam. As of the 2020 Olympic Games in Tokyo, she and Larisa Latynina are the only gymnasts to win the gold medal in individual all-around in consecutive Olympic games as well as the only female gymnast to defend her gold medal in the vault apparatus. Her use of the "Jarabe tapatío" as the music for her floor routine and her subsequent marriage in the city made her immensely popular with the Mexican crowd. Protest at the 1968 Olympics Čáslavská's wins at the 1968 Olympics were particularly poignant because of the political turmoil in Czechoslovakia. She had publicly voiced her strong opposition to Soviet-style Communism and the Soviet invasion, and had signed Ludvik Vaculík's protest manifesto "Two Thousand Words" in the spring of 1968. Consequently, to avoid being arrested, she spent the weeks leading up to the Olympics hiding in the mountain town of Šumperk, and was only granted permission to travel to Mexico City at the last minute. At the Olympics, where she once again faced Soviet opposition, Čáslavská continued to subtly voice her views. After she appeared to have won the gold medal on floor outright, the judging panel curiously upgraded the preliminary scores of Soviet Larisa Petrik, and declared a tie for the gold instead. All of this occurred on the heels of another very controversial judging decision that cost Čáslavská the gold on beam, instead awarding the title to Soviet rival Natalia Kuchinskaya. Clearly disheartened and angered by
