Step-by-step explanation:
In 1831, William Lloyd Garrison launched The Liberator to advocate for the abolition of slavery. Garrison was a prominent figure in the abolitionist movement and dedicated his life to promoting immediate emancipation and black citizenship. The newspaper became a critical platform for expressing his ideology of ending slavery forthwith, without any delays or gradual measures. Garrison's impassioned pleas for racial equality and an end to the institution of slavery were unwavering, and he played a significant role in organizing the American Anti-Slavery Society which he later presided over, thereby committing to the cause of national and Christian redemption.
