Frankish synods of 829

The Frankish church held four synods simultaneously throughout the Frankish Empire on the octave of Pentecost in 829. These were held in Lyon, Mainz, Paris and Toulouse. They were followed by an imperial diet in Worms in August.

According to Gerhard Schmitz, the synods of 829 mark a break in the history of Frankish legislation. Until then, Louis the Pious's government was characterised by continuity with his father's. Carine van Rhijn, however, emphasises the similarity of the 829 synods to the reform councils of 813.
