The struggles of John Keats during his adolescence, including the loss of family members and persistent illness, deeply influenced his poetry. The death of his brother, Tom, particularly left a mark on Keats, intertwining his themes of mortality and love. His experiences in a lower socio-economic background also fueled his desire to escape into the romantic ideal of beauty, which he often expressed in his poems. This blend of personal grief and yearning for beauty became a powerful force, enabling Keats to explore profound emotional landscapes in his work.
