Why is Williams' "The Red Wheelbarrow" one of the most important poems of this Modernist movement?

Let us remember that in his poetry William Carlos Williams
was looking for a return to the barest essentials in poetry. In this way his form, style
and diction is marked by its sparseness and its simplicity. Also, he chose to write
about commonplace subjects. Thus it is that this poem only consists of sixteen words and
takes its subject from a red wheelbarrow. In this poem, Williams appears to have
selected ordinary objects to suggest that every single moment of life is significant,
whether or not it actually seems unforgettable at the time. He further seems to suggest
that the beauty fo the world is made up of such varied and profoundly ordinary objects.
The vivid mention of the colour of the "red wheel barrow" that is "glazed with rain"
lying next to the "white chickens" seems to create a specific moment in time that is
emblazoned upon the brain of the poet. The way in which the poem does not use figurative
language and further refuses to use the central image as a symbol shows how Williams was
trying to challenge traditional assumptions about what a poem is and how it should be
interpreted. This is why this poem is such an important example of Modernist
poetry.
