Over the next generations, the Jewish population of Bessarabia grew significantly. Unlike most of the rest of the Russian Empire, in Bessarabia, Jews were allowed to settle in fairs and cities. Tsar Nicholas I issued an ukaz (decree) that allowed Jews to settle in Bessarabia "in a higher number", giving settled Jews two years free of taxation. At the same time, Jews from Podolia and Kherson Governorates were given five years free of taxation if they crossed the Dniester and settle in Bessarabia.
