Research overview: historic collapse of lion range

Lions once ranged across Africa, southeast Europe, the Middle East, and into India, but have lost the overwhelming majority of that historical distribution. This overview surveys research reconstructing the lion's former range and quantifying its contraction to a small remnant concentrated in sub-Saharan Africa plus the Indian relict. Studies use historical records, archaeology, and habitat modelling to chart how agriculture, persecution, and prey loss erased lions from entire continents and regions over centuries. Understanding the scale and pace of this collapse provides essential context for present-day conservation, showing that today's strongholds are the last fragments of a once-vast range. The overview connects deep-time range loss to current threats, reinforcing that the lion's decline is a long historical process now reaching its most critical stage in the remaining African populations.
