Tsarist policy towards the Jews of Poland alternated between harsh rules, and inducements meant to break the resistance to large-scale conversion. In 1804, Alexander I of Russia issued a "Statute Concerning Jews", meant to accelerate the process of assimilation of the Empire's new Jewish population. The Polish Jews were allowed to establish schools with Russian, German or Polish curricula. They could own land in the territories annexed from Poland. However, they were also restricted from leasing property, teaching in Yiddish, and from entering Russia. They were banned from the brewing industry. The harshest measures designed to compel Jews to merge into society at large called for their expulsion from small villages, forcing them to move into towns. Once the resettlement began, thousands of Jews lost their only source of income and turned to Qahal for support. Their living conditions in the Pale began to dramatically worsen.
