The Treaty of Le Goulet was signed by Kings John of England and Philip II of France in May 1200.
The treaty was a victory for Philip in asserting his legal claims to overlordship over John's French lands.
The terms of the treaty signed at Le Goulet, an island in the middle of the Seine river near Vernon in Normandy, included clarifications of the feudal relationships binding the monarchs.
Philip declared John deposed from his fiefs for failure to obey a summons in 1202 and war broke out again.
Philip moved quickly to seize John's lands in Normandy, strengthening the French throne in the process.
