As more and more slaves made their escape, southerners became more insistent on strict enforcement of the Fugitive Slave Act. Especially after the Act was strengthened in the Compromise of 1850, northerners resented the fact that southerners could come into their territory and force northerners to assist their recovery efforts. And when northerners refused to help, the south was further angered.
