During Mayor Daley's tenure in Chicago, Puerto Ricans in Lincoln Park and several Mexican communities were evicted from prime real estate areas near the Loop, Lakefront, Old Town, and Lakeview neighborhoods. The rationale was to increase property tax revenues by luring White suburbanites and creating a suburb within the city. The urban renewal resulted in the eviction of Latino and poor families from their neighborhoods and increased police abuses. Some Young Lords were involved in the Puerto Rican June 1966 Division Street Riots in Wicker Park and Humboldt Park. The 1968 Democratic Convention protests in Grant Park and the adjacent Lincoln Park Neighborhood, resulted in the Young Lords, under the leadership of founder Jose Cha Cha Jimenez, to join with others to form a broader civil and human rights movement. Puerto Rican self-determination and the displacement of Puerto Ricans and poor residents became the primary organizing focus. The Young Lords organization also began to train students and youth to take on the leadership to organize the Latino community on a national level.
