Overview
The Kingdom of Jerusalem, also known as the Crusader Kingdom, was one of the Crusader states established in the Levant immediately after the First Crusade. It lasted for almost 200 years, from the accession of Godfrey of Bouillon in 1099 until the fall of Acre in 1291. Its history is divided into two periods with a brief interruption in its existence, beginning with its collapse after the siege of Jerusalem in 1187 and its restoration after the Third Crusade in 1192.

10 dated territorial extents on record from Cliopatria. Areas are measured off the recorded polygons; the line steps because each extent holds until the next one is recorded — nothing is interpolated.
The record
The best-attested series in each category; where several projects publish the same quantity, the one with the most observations is shown. Each row is the most recent value the record holds at or before 1293 CE, shown with the year that value belongs to. Some statistical series also publish forward projections — the year column is the honest guide. Nothing on this page is interpolated or estimated by us.
