The German aiming system was replaced with an improved Romanian system and the maximum range was increased to 6,500 meters, being superior to the 6,300 meters maximum range of its German counterpart. Maximum elevation was also increased from 40° to 60°. Thirty batteries were converted by Arsenalul Armatei before and during World War I.

Its leader was Aurel Onciul, seconded by Florea Lupu, both of whom were adversaries of the conservative and elitist Romanian National People's Party (PNPR). Rejecting sectarianism, the PȚD combined Austrian and Romanian nationalism, as Onciul argued that Romanian aspirations could only be fulfilled inside the multi-ethnic empire. For this reason, and for its role in dividing the Romanian vote, the party was often accused of double-dealing.

WSeara was a daily newspaper published in Bucharest, Romania, before and during World War I. Owned by politician Grigore Gheorghe Cantacuzino and, through most of its existence, managed by the controversial Alexandru Bogdan-Pitești, it was an unofficial and unorthodox tribune for the Conservative Party. Its involvement in politics sparked numerous scandals, the longest of which came during the neutrality period (1914–1916). Strongly anti-Slavic, Seara stood out in that context for supporting the German Empire and Central Powers, and was widely alleged of having been financed by a German propaganda machine. In 1914, it was purchased by German businessmen, but continued to register mediocre success in comparison with its pro-Entente competitors. In late 1916, after Romania decided in favor of the Entente, Seara was disestablished.
