Catherine II's Instruction to the Commission on the success of Peter the Great's reforms
Russia Is a European Power.
The proof of this is as follows. The changes that Peter the Great undertook in Russia met with the greater success because the manners prevailing at that time were wholly unsuited to the climate, having been brought to us by the intermingling of various peoples and by the conquest of foreign lands. Peter the First, introducing European manners and customs among a European people, found such facilities there as he himself had not expected.
