Serfdom continued in practice in Russia for decades and often serfs became indebted to the landowners in a form of financial bondage that pretty much lasted until the Russian revolution, where...well things didn't get much better for them.

The fact that serfdom de-facto remained is one of the primary reasons Russia's industrialization lagged the rest of Europe for so long as factories didn't get the initial cheap labour. It was only finally fully picking up steam (pun not intended) when WW1 broke out.
