During their time in exile, the Decembrists fundamentally influenced Siberian life. Their presence was most definitely felt culturally and economically, political activity being so far removed from the "pulse of national life" so as to be negligible. While in Petrovsky Zavod, Decembrists taught each other foreign languages, arts and crafts, and musical instruments. They established "academies" made up of libraries, schools, and symposia. In their settlements, Decembrists were fierce advocates of education, and founded many schools for natives, the first of which opened at Nerchinsk. Schools were also founded for women, and soon exceeded capacity. Decembrists contributed greatly to the field of agriculture, introducing previously unknown crops such as vegetables, tobacco, rye, buckwheat, and barley, and advanced agricultural methods such as hothouse cultivation. Trained doctors among the political exiles promoted and organized medical aid. The homes of prominent exiles like Prince Sergei Volkonsky and Prince Sergei Trubetskoi became social centers of their locales. All throughout Siberia, the Decembrists sparked an intellectual awakening: literary writings, propaganda, newspapers, and books from European Russia began to circulate the eastern provinces, the local population developing a capacity for critical political observation. The Decembrists even held a certain influence within Siberian administration; Dimitry Zavalishin played a critical role in developing and advocating Russian Far East policy. Although the Decembrists lived in isolation, their scholarly activities encompassed Siberia at large, including its culture, economy, administration, population, geography, botany, and ecology. Despite restricted circumstances, the Decembrists accomplished an extraordinary amount, and their work was deeply appreciated by Siberians.
