The Victorian era (1837-1901) was marked by social contrasts, technological advances, and the rise of literary criticism, most notably through Matthew Arnold, who stressed the importance of poetry as a 'criticism of life.' Arnold's critical approach emphasized objective standards in literature, distinguishing between personal and historical judgments to reveal 'real estimates' of poetic worth while imploring readers to focus on the moral and emotional depth of poetry. Despite being overshadowed by contemporaries like Tennyson and Browning, Arnold's intellectual contribution to poetry and criticism remains significant for understanding Victorian literature's transition to modernism.
