Berthold I of Neuchâtel

Berthold I of Neuchâtel (c. 1183–1259) was the son of Rodolphe II. In 1214, under his uncle Ulrich III's guardianship, a charter let burghers appeal to Lausanne's bishop against him.

After partitioning with Ulrich in 1218, Berthold took the title of lord and his uncle that of count; after Ulrich's death in 1225 he styled himself count. After Basel's bishop burned Neuchâtel in 1249, Berthold founded Nugerol in 1253 and set up a Three Estates court and town council. His son by Richenza of Frobourg was Rodolphe III.
