2150s Dalek invasion of Earth

The First Dalek War was the first war between the Daleks and Humanity, which presumably occured between the 22nd century Dalek invasion and the Second Dalek War of the 26th century.

The Thals referred to the period in their history after the First Doctor helped them rise up against the Daleks as the First Dalek War. (DW: The Daleks, Planet of the Daleks)
