The Polish communities of Jackowo and Wacławowo appeared in the late 19th and early 20th centuries as Polish settlement spread further northwest along Milwaukee Avenue. The neighborhood experienced its heyday as the cultural nexus of Chicago's Polonia during the 1980s and 1990s with the so-called Solidarity and Post-Solidarity waves of Polish migration to Chicago, including a number of political refugees. Until the recent installation of an automated system, on Sunday mornings the CTA driver would announce "Yats- koh- voh", signaling the stop for St. Hyacinth Basilica as Poles shuttled off the bus on their way to Mass. Local landmarks and institutions increasingly became revitalized and renewed while taking on an increasingly ethnic hue by catering to these recent arrivals from Poland. The historic Milford Theatre served as the central Polish cinema arts venue like Jefferson Park's Gateway Theater today, with locals giving it the nickname ""Cinema Polski"", drawing even street photographer Vivian Maier.
