system which was based on Montesquieu's doctrine of separation of powers, and which restored the bicameral Sejm consisting of a chamber of deputies (to which alone the name of "Sejm" was from then on applied) and the Senate. In 1919, Roza Pomerantz-Meltzer, a member of the Zionist party, became the first woman ever elected to the Sejm. The legal content of the March Constitution allowed for Sejm supremacy in the system of state institutions at the expense of the executive powers, thus creating a parliamentary republic out of the Polish state. An attempt to strengthen executive powers in 1926 (through the August Amendment) proved too limited and largely failed in helping avoid legislative grid-lock which had ensued as a result of too-great parliamentary power in a state which had numerous diametrically-opposed political parties sitting in its legislature. In 1935, the parliamentary republic was weakened further when, by way of, Józef Piłsudski's May Coup, the president was forced to sign the April Constitution of 1935, an act through which the head of state assumed the dominant position in legislating for the state and the Senate increased its power at the expense of the Sejm. On 2 September 1939, the Sejm held its final pre-war session, during which it declared Poland's readiness to defend itself against invading German forces. On 2 November 1939, the President dissolved the Sejm and the Senate, which were then, according to plan, to resume their activity within two months after the end of the Second World War; this, however, never happened. During wartime, the National Council (1939–1945) was established to represent the legislature as part of the Polish Government in Exile. Meanwhile, in Nazi-occupied Poland, the Council of National Unity was set up; this body functioned from 1944 to 1945 as the parliament of the Polish Underground State. With the cessation of hostilities in 1945, and subsequent rise to power of the Communist-backed Provisional Government of National Unity, the Second Polish Republic legally ceased to exist. Polish People's Republic The Sejm in the Polish People's Republic had 460 deputies throughout most of its history. At first, this number was declared to represent one deputy per 60,000 citizens (425 were elected in 1952), but, in 1960, as the population grew, the declaration was changed: The constitution then stated that the deputies were representative of the people and could be recalled by the people, but this article was never
