The career of the brothers, Szmojło and Gdal Ickowicz, who leased the Radziwiłł holdings from 1740 to 1745, exemplifies the possibilities and risks of estate leasing for Jews. Their success was based on their entrepreneurial skills in using leases to improve their trading activity, and mercantile profits to expand their leaseholds. Their willingness to change the economic status quo by unilaterally increasing customary dues allowed them to improve estate profitability, boosting Hieronim Florian Radziwiłł’s revenues. They thus won his confidence, with Szmojło becoming his personal agent. Their highhandedness made the brothers extremely unpopular. A peasant uprising ensued, during which Radziwiłł supported them. For as long as they could provide him with increased revenues, they flourished. Once they could not, they were at his mercy. When he needed income that Szmojło could not find, Radziwiłł arrested him, confiscated his fortune, and left him to die in prison.
