The Regiment de la Cosa Pública (Government of the Republic) is a work that has 38 chapters and that was written in Catalan by Francesc Eiximenis in 1383. It was just written after Eiximenis' arrival in Valencia, and it was dedicated to the jurats (representatives of the city).
This dedicatory to the "jurats" is what gives us some clues about the period when this book was written.[1] Another work by Eiximenis, the Dotzè del Crestià (Twelfth of the Christian), which is a part of his encyclopaedia called Lo Crestià (The Christian), includes, as its chapters 357-395, the Regiment de la Cosa Pública. As an independent work it was only published in an incunabulum edition in Valencia on 28 January 1499 by the German printer Cristòfor Cofman.
This book has a strong influence from John of Wales' Communiloquium, as some studies have proved.[2] On the other hand, it seems that some parts of this book were not written by Eiximenis, and could have been added later. These ones are the famous twenty difficulties, thirty-two beauties and the end of the prologue, together with the end of the epilogue.[3] The Regiment de la Cosa Pública expresses quite well the essential features of Francesc Eiximenis' social and political thought. It also explains the basic guidelines of what has been called "Catalan and Aragonese pactism".
