Poland has a multi-party political system. On the national level, Poland elects the head of state – the president – and a legislature. There are also various local elections, referendums and elections to the European Parliament. Poland has a long history of public elections dating back several centuries, beginning with the elections to Sejm in Łęczyca (known as the First Sejm) in 1182. Notably, since the Sejm of 1493, Polish kings were obliged to call regular Sejms and regional elections (sejmiks) every two years. From 1573 until 1795 the state system of elective monarchy in Poland required the royal elections of monarchs as well during the Sejm proceedings. The first modern and free elections in 20th-century Poland were held in 1919, two months after the country regained independence in 1918 after over a century of partition and occupation by foreign powers. After the Second World War, Poland fell into the Soviet sphere of influence as a satellite state and became controlled by the communists, who rigged the elections of 1947 to ensure they controlled the entire Polish government. There were regular elections in Poland from that time on; however, no elections until the groundbreaking elections of 1989, marking the fall of communism, were free. The Polish communists secured a majority of the lower house seats in 1989, but allowed opposition parties to take up seats. History The first Polish Sejm was called in 1182. Since the Sejm of 1493, called by king John I Olbracht in 1493, Sejms were to be held every 2 years. There were also special Sejms when needed, for example the coronation sejms. The most famous Sejms included the Sejm Niemy or the Silent Sejm of 1717 which marked the beginning of Russian control over Polish internal affairs; the subsequent Repnin Sejm or the Sejm of 1767/1768, whose terms were dictated by the Russian ambassador Repnin; the Great Sejm – or the Four-Years Sejm of 1798–1792, which voted for the May Constitution of Poland; and the Grodno Sejm – last Sejm of the First Republic. Since the death of Sigismund II Augustus, last of the Jagiellonian dynasty, and following a brief period of interregnum, the entire nobility (szlachta) of the Commonwealth (10% of the population) could take part in the elections of the monarchs. Last elected king was Stanisław August Poniatowski in 1764. He abdicated in 1795 after the partitions of Poland ended the existence of
