of Chicago, built in the so-called 'Polish Cathedral style'. Polish immigration into the area accelerated during and after World War II when as many as 150,000 Poles are estimated to have arrived between 1939 and 1959 as Displaced Persons (DPs). Like the Ukrainians in neighboring Ukrainian Village, they clustered in established ethnic enclaves like this one that offered shops, restaurants, and banks where people spoke their language. Division Street was referred to as Polish Broadway. Poet John Guzlowski whose parents first came to the area as DPs commented on growing up in the area in the 1950s that "it felt like everyone was a Pole", a place where the local store owners, priests, cops, trash men, teachers, librarians all either spoke Polish or had family that did.

Additionally Puerto Ricans and other Latinos displaced by urban renewal in Old Town and Lincoln Park began moving in. In 1960 Latinos comprised less than 1 percent of West Town's population, but by 1970 that number was up to 39 percent. Split from the Lincoln Park neighborhood only by the Kennedy Expressway in the late 1950s and 1960s, it contained the second-largest concentration of Puerto Ricans in Chicago. It was the original home to the largest Latino gang at the time, the Latin Kings. The Young Lords, a human rights movement, held sit-ins with L.A.D.O. at the Wicker Park Welfare Office and large nonviolent marches to city hall. Urban renewal projects were undertaken to combat "urban blight" in some parts of the neighborhood, but
