Its major activists included Walery Sławek, Kazimierz Bartel, Kazimierz Świtalski, Aleksander Prystor, Józef Beck, Janusz Jędrzejewicz, Wacław Jędrzejewicz, Adam Koc, Leon Kozłowski, Ignacy Matuszewski, Bogusław Miedziński, Bronisław Pieracki, Adam Skwarczyński, and Janusz Franciszek Radziwiłł.

[6][7][8] In 1993, Lech Wałęsa, then President of Poland, founded a Nonpartisan Bloc for Support of Reforms, in Polish Bezpartyjny Blok Wspierania Reform, likewise abbreviated "BBWR," which was meant to revive some of the traditions of the prewar "BBWR" and to form a parliamentary grouping explicitly supportive of President Wałęsa.

They were united by the personality of Piłsudski, whom they supported, and the BBWR had several targets: to carry out changes in the constitution, to keep the National Democracy political movement away from the parliament, and to attract conservatives and business circles.

In response, opposition parties united, creating the so-called Centrolew, and organizing a mass anti-government demonstration in Kraków, on June 29, 1930.

Facing the financial crisis (see Great Depression), Prystor decided to cut public spending in order to balance the budget.

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).

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.

After the death of Józef Piłsudski (May 12, 1935), the weakened BBWR continued to exist until October 30, when Walery Sławek dissolved it.
