They consisted mostly of progressive-minded landowners and industrialists, the middle class, and some intellectuals of Russian controlled Congress Poland.
The faction had its origins in the Towarzystwo Rolnicze (Agricultural Society) started by Count Andrzej Artur Zamoyski in 1858.
While the Whites supported ending serfdom, unlike the "Red" faction, they advocated for some kind of compensation to be made to the landlords.
Also unlike the Reds, the Whites generally opposed the idea of an armed insurrection against Russia, seeing it as doomed to failure.
Instead, they tried to use diplomacy and the support of other European powers to win greater autonomy, a separate administration, and a native Polish army for Congress Poland.
