The constructions of most of the early gothic cathedrals were started under the reign of Louis VII. This paper investigates the actual relationship between Louis VII and the construction of the cathedrals. Regarding the finances of the constructions, Louis VII gave economic aid in some case, but they weren't the great patronages. As for his power of ruling over the "royal bishopric", it reduced under his reign. Thus. Louis VII wasn't the great patron of the early gothic style. The fact that the king renounced his right to deprive the bishops' possessions might help the construction of the gothic cathedrals.
