It was based on the so-called “group of colonels”, who were personal friends of Piłsudski. On December 6, 1929, the Sejm passed the motion of no confidence, and Bartel replaced Świtalski. The new government was dissolved on March 29, 1930, and the new Prime Minister was Walery Sławek. In response, opposition parties united, creating the so-called Centrolew, and organizing a mass anti-government demonstration in Kraków, on June 29, 1930. On August 25, 1930, Józef Piłsudski took the post of Prime Minister, and on September 9, the first arrests of opposition politicians took place. The parliament was dissolved, and the opposition leaders were imprisoned in the Brest Fortress. In the 1930 election, which was also called the “Brest election”, the BBWR won 249 seats in the Sejm, and 75 in the Senate. On December 4, 1930, the second government of Walery Sławek was created. It existed until May 1930, when Aleksander Prystor became a new Prime Minister. Facing the financial crisis (see Great Recession), Prystor decided to cut public spending in order to balance the budget. In 1933, a program of public works was created to reduce widespread unemployment. Furthermore, in 1932 - 1933, the BBWR government carried out significant educational reform. Simultaneously, oppositional activities were curbed, following three new bills, which limited the means of street protests and possibilities of creating new movements (see also Brest trials). In the summer of 1933, Prystor lost the confidence of Józef Piłsudski and was replaced by Janusz Jedrzejowicz. At the same time, Piłsudski and his subordinates began drafting the April Constitution, and on May 15, 1934, the new government of Leon Kozłowski was created. In June of the same year, Minister of Internal Affairs Bronisław Pieracki was murdered by the Organization of Ukrainian Nationalists. The government in response opened the Bereza Kartuska detention camp. After the death of Józef Piłsudski (May 12, 1935), the weakened BBWR continued to exist until October 30, when Walery Sławek dissolved it. The tradition of the movement was continued by the Camp of National Unity, formed in February 1937. BBWR in the 1990s The Nonpartisan Bloc for Support of Reforms (Bezpartyjny Blok Wspierania Reform, also abbreviated BBWR), was founded to continue the traditions of pre-war Nonpartisan Bloc for Cooperation with the Government. Its creation was announced by Lech Wałęsa on June 1, 1993, during a press conference in the garden of the Belweder. The movement was registered on
