"Invictus" is a short Victorian poem by the English poet William Ernest Henley (1849–1903). It was written in 1875 and published in 1888. It reads as follows:

Out of the night that covers me,

Black as the pit from pole to pole,

I thank whatever gods may be

For my unconquerable soul.

In the fell clutch of circumstance

I have not winced nor cried aloud.

Under the bludgeonings of chance

My head is bloody, but unbowed.

Beyond this place of wrath and tears

Looms but the Horror of the shade,

And yet the menace of the years

Finds, and shall find me, unafraid.

It matters not how strait the gate,

How charged with punishments the scroll,

I am the master of my fate:

I am the captain of my soul.

Henley's literary reputation rests almost entirely on this single poem. In 1875 one of Henley's legs required amputation due to complications arising from tuberculosis. Immediately after the amputation he was told that his other leg would require a similar procedure. He chose instead to enlist the services of the distinguished surgeon Joseph Lister, who was able to save Henley's remaining leg after multiple surgical interventions on the foot.

While recovering in the infirmary, he was moved to write the verses that became "Invictus". This period of his life, coupled with recollections of an impoverished childhood, were primary inspirations for the poem, and play a major role in its meaning.
