Czech resistance to German Nazi occupation during World War II is a scarcely documented subject, by and large a result of little formal resistance and an effective German policy that deterred acts of resistance or annihilated organizations of resistance. In the early days of the war, the Czech population participated in boycotts of public transport and some mass protest demonstrations took place.
International Students' Day commemorates the anniversary of the 1939 Nazi storming of the University of Prague after demonstrations against the German occupation of Czechoslovakia. Nazi Germany closed all Czech universities and colleges, sent over 1200 students to Nazi concentration camps, and had nine student leaders executed (on November 17).
The Czech resistance network that existed during the early years of the Second World War operated under the leadership of Czechoslovak president Edvard Beneš, who together with the head of Czechoslovak military intelligence, František Moravec, coordinated resistance activity while in exile in London. In the context of German persecution, the major resistance groups consolidated under the Central Leadership of Home Resistance (Ústřední vedení odboje domácího, ÚVOD). It served as the principal intermediary between Beneš and the Protectorate, which was in existence through 1941. Its long-term purpose was to serve as a shadow government until Czechoslovakia's liberation from Nazi occupation.
The three major resistance groups that consolidated under ÚVOD were the Political Centre (Politické ústředí, PÚ), the Committee of the Petition "We Remain Faithful" (Petiční výbor Věrni zůstaneme, PVVZ), and the Nation's Defence (Obrana národa, ON). These groups were all democratic in nature, as opposed to the fourth official resistance group, the Communist Party of Czechoslovakia (KSČ). Most of their members were former officers of the disbanded Czechoslovak Army. In 1941, ÚVOD endorsed the political platform designed by the leftist group PVVZ, titled "For Freedom: Into a New Czechoslovak Republic”. In it, ÚVOD professed allegiance to the democratic ideals of past-Czechoslovak president Tomáš Masaryk, called for the establishment of a republic with socialist features, and urged all those in exile to stay in step with the socialist advances at home.
