Following the end of World War II and the imposition of Stalinism in Poland, the museum remained under Minich's directorship and moved to the Poznański family palace in 1948.

During the 1950s, in the wake of the Khrushchev Thaw, the museum returned to a more robust international program, collaborating with Western gallerists and artists such as Denise René and Michel Seuphor, among others.

[4] Its programme coincides with avant-garde project worked out at the turn of the 1920s and 1930s by the “a.r.” group or, more precisely, by Władysław Strzemiński, Katarzyna Kobro and Henryk Stażewski) and with the idea developed by Ryszard Stanisławski (Muzeum's director in 1966–1992) of a “museum as a critical instrument”.

Through exhibition, research, educational and publishing programme, the Muzeum strives to practice the idea of art as a way to experience, feel and understand the reality, which was a part of avant-garde dream of creative life available to all.

[6] The Collection in its ideological dimension reflects Strzemiński's artistic preferences, although its final shape was the product of the activities of many people, including Henryk Stażewski, Hans Arp and Michel Seuphor.

The collection also includes artworks of artists representing Cubism (e.g., Fernand Léger, Louis Marcoussis), Futurism (Enrico Prampolini), Dada (Kurt Schwitters), Surrealism (Max Ernst, Kurt Seligmann), Formism (e.g., Leon Chwistek, Tytus Czyżewski), “pure form” (Stanisław Ignacy Witkiewicz) or Unism (Władysław Strzemiński).

[9] The collection of contemporary art was expanded with, inter alia, works by Jonasz Stern, Jerzy Nowosielski, and Alina Szapocznikow.

The collection of works from the first Construction in Process (Polish: Konstrukcja w Procesie) festival donated by “Solidarity” (e.g. Peter Downsbrough, Dan Graham, and Richard Nonas) enriched the representation of minimal art.

Prospects of having a building that could meet exhibition requirements of avant-garde art became real with plans to develop the Manufaktura Shopping and Entertainment Centre in the former Izrael Poznański factory.

[11] ms1, Więckowskiego 36 (Maurycy Poznański palace) – with Neoplastic Room designed by Władysław Strzemiński, which was the core of the exposition of “a.r.” group International Collection of Modern Art.

The collection includes artworks by artists, such as: Max Ernst, Władysław Strzemiński, Katarzyna Kobro, Kurt Schwitters, Kazimierz Podsadecki, Enrico Prampolini, Janusz Maria Brzeski, Teresa Żarnower, Mieczysław Szczuka, Włodzimierz Borowski, Derek Boshier, Christian Boltanski, Joseph Beuys, Bridget Riley, Alina Szapocznikow, Ewa Partum, Krzysztof Wodiczko, Edward Krasiński, Ali Kazma, Barbara Hammer, Agnieszka Kalinowska, Zofia Kulik, Jadwiga Maziarska, Erna Rosenstein, Jadwiga Sawicka, Ahlam Shibli, Mladen Stilinović, Mona Vătămanu & Florin Tudor, Haegue Yang, Konrad Smoleński, Cezary Bodzianowski, Zbigniew Libera, Artur Żmijewski, Julita Wójcik, Antje Majewski, and Allan Sekula.

[12] Opened on 24 February 2014 in ms2, a division of Muzeum of Art in Łódź, is an overview of the collection featuring works by artists active in the 20th and 21st centuries.

The exhibition occupies three floors in the premises owned by Muzeum Sztuki located in the shopping and entertainment centre Manufaktura in Łódź.

[13] “Atlas of Modernity” is another stage in the works on Muzeum Sztuki in Łódź collection that have been continued since 2008 and “whose goal is to research, re-interpret and update the meaning of artworks included in the collection.”[14] The exhibition refers to the idea of art historian Aby Warburg and his project “Mnemosyne Atlas”, it departs from both the chronological arrangement of works of art and the idea of a ‘permanent exhibition’.

The exposition “has given up typical linearity that organises museum’s collection against a timeline of art history and groups artworks into schools, trends, styles or tendencies.”[15] Works focus around 14 notions connected with the idea of modernity: “museum”, “autonomy”, “capital”, “machine”, “city”, “progress”, “experiment”, “propaganda”, “norm”, “tradition”, “catastrophe”, “me”, “emancipation”, and “revolution”; “creating a ‘collage’ of artworks from different periods representing different aesthetics and artistic attitudes around these notions; the exhibition poses questions about how the phenomena changed, how the way they were perceived altered and, most importantly, to what extent they shape our today's reality.”[16] The exhibition has been prepared by a curatorial team headed by Jarosław Suchan, the Muzeum’s director, and composed of: Aleksandra Jach, Paulina Kurc-Maj, Maria Morzuch, Anna Saciuk-Gąsowska, Joanna Sokołowska, Katarzyna Słoboda, and Magdalena Ziółkowska.

The Muzeum accomplishes this goal through, inter alia, cooperation with other museums in the world, publishing activities, education effort (workshops, lectures, guided tours), and its media presence (in cooperation with TVP kultura TV channel, Muzeum Sztuki creates “Kulturanek” [Cultural Morning] - a series of programmes on art addressed to young audience).
