In Memoriam A.H.H.

In Memoriam is Tennyson's elegiac tribute to his friend Arthur Henry Hallam, who died in 1833 at the age of 22. Tennyson wrote this long poem over 17 years as a chronicle of his mourning process. The poem became a favorite of Queen Victoria when she was grieving for her husband, and was one of the most popular and artistically influential poems of the Victorian period. (Summary by gloriana).
