As the conflict between civil and religious authorities escalated, in order to maintain civil order Oldenbarnevelt eventually proposed that local authorities be given the power to raise troops (the Sharp Resolution of August 4, 1617). Such a measure undermined the unity of the Republic's military force, the very same reason Spain had managed to retake so much lost territory in the 1580s, something the Captain-General of the republic, Maurice of Nassau, Prince of Orange coulnd't allow with the treaty nearing its end. Maurice seized the opportunity to solidify the preeminence of the Gomarists, whom he had supported, and to eliminate the nuisance he perceived in Oldenbarnevelt (the latter had previously brokered the Twelve Years' Truce with Spain in 1609 against Maurice's wishes). During this time Grotius made another attempt to address ecclesiastical politics by completing "De Imperio Summarum Potestatum circa Sacra", on "the relations between the religious and secular authorities...Grotius had even cherished hopes that publication of this book would turn the tide and bring back peace to church and state".
