King organized a campaign in Birmingham, one of the most segregated cities in the US, by planning to fill the jails with protesters, as well as boycott businesses, and enrage the Public Safety Commissioner Eugene "Bull" Connor. King, like many others, was eventually arrested. The pressure continued with the "children's crusade" by recruiting young students to fill the jails. Connor's forces used force (water cannons, clubs, dogs) to break up the protest. The entirety of the situation was broadcast to the nation until a negotiation was finally achieved, but hard feelings still remained.
