After the Polish-Russian War, Ostrołęka became one of the most destroyed cities. Although it suffered great losses, Ostrołęka stayed a district city of [[Płock]]'s Province. Ostrołęka's economy greatly declined. Nearly all the city's craftsmen became bankrupt. Only products of Ostrołęka's amber works were still supplied all over [[Europe]]. Ostrołęka got refunds from the Tsar's Treasury. However, it took a long time before it rose from its downfall. In 1847 a monument commemorating Russian Army's victory in the [[Battle of Ostrołęka (1831)|battle of Ostrołęka]] was raised on 26 May 1831. At the time of January's insurrection, no battles took place nearby Ostrołęka, as the Tsar placed a quite large Russian detachment in the city worrying of another Kurp Uprising. In 1864, after the Russian government's order, the Benedictines left Ostrołęka and the monastery buildings were placed under the parish-priest authority. {{Citation needed|date=September 2010}}

Until the [[First World War]], the city managed to develop, but it was still a relatively unremarkable small town. The First World War destroyed its peaceful and monotonous character. Confiscation and forced labor devastated the economy caused rising prices for essential products, and generally caused the city to decline. In 1915, military operations in the territory of Polish Kingdom intensified. By July, the city was situated on the front line during the [[Great Retreat (Russian)|Russian Great Retreat]],<ref name="PB2">{{cite book |last1=Buttar |first1=Prit |title=Germany Ascendant, The Eastern Front 1915 |date=2017 |publisher=Osprey Publishing |location=Oxford |isbn=9781472819376 |pages=295}}</ref> and in August 1915, Germans crossed the river Narew and entered the ruined city. At the time of the German occupation, life in Ostrołęka was as hard as in the time of Russian occupation. Between the years of 1916 and 1918, the Germans greatly exploited the forests for timber. To make transporting the wood easier, they built {{convert|40|km|0|abbr=on}} of road from Ostrołęka to Myszyniec and a narrow-gauge railway line.
