Following an 11-month military campaign, the Kingdom of Poland lost its semi-independence and was integrated much more closely with the Russian Empire. This was formalized through the issuing of the Organic Statute of the Kingdom of Poland by the Emperor in 1832, which abolished the constitution, army and legislative assembly. Over the next 30 years, a series of measures bound Congress Poland ever more closely to Russia. In 1863 the January Uprising broke out but lasted only two years before being crushed. As a direct result, any remaining separate status of the kingdom was removed and the political entity was directly incorporated into the Russian Empire. The unofficial name "Privislinsky Krai" (), i.e., 'Vistula Land', replaced 'Kingdom of Poland' as the area's official name and the area became a "namestnichestvo" under the control of a namiestnik until 1875, when it became a Guberniya.
