When did the last ice age take place?

According to Wikipedia, the last ice age took place between 110,000 and 12,000 years ago. There have been exactly five ice age periods throughout Earth's history.

There are many factors that lead to the formation of glacial-interglacial cycles and ice age periods. One of the most significant factors that contribute to these periods is the ever-moving continental plates. The plate-tectonic movement is responsible for changes in atmospheric circulation patterns and the way the continents are arranged. Other factors that have contributed to the formation of these periods include volcanic eruptions and the amount of carbon dioxide found in the atmosphere.
