How long ago did the last ice age last begin?

The last ice age, known as the Last Glacial Maximum, began approximately 26,000 years ago and lasted until about 19,000 years ago. It was part of the Pleistocene Epoch and marked a period of significant global cooling and ice sheet expansion. The climate began to warm around 15,000 years ago, leading to the retreat of glaciers and the end of the last ice age.
