The Sudebnik of 1550 increased the amount of pozhiloye and introduced an additional tax called (, or transportation fee), in case a peasant refused to bring the harvest from the fields to his master. A temporary (, or forbidden years) and later an open-ended prohibition for peasants to leave their masters was introduced by the ukase of 1597 under the reign of Boris Godunov, which took away the peasants' right to free movement around Yuri's Day, binding the vast majority of the Russian peasantry in full serfdom. These also defined the so-called fixed years (, ), or the 5-year time frame for search of the runaway peasants. In 1607, a new ukase defined sanctions for hiding and keeping the runaways: the fine had to be paid to the state and pozhiloye – to the previous owner of the peasant.
