Three quarto volumes of Diplomata regum et imperatorum Germaniae and one of Diplomata Karolingorum had been published by 1909.
The Leges are divided into Leges nationum Germanicarum, Capitularia regum Francorum, Concilia, Constitutiones imperatorum et regum and Formulae.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "imperatorum" in a variety of sentences. We hope that you will now be able to make sentences using this word.
