To some extent, the Decembrists were in the tradition of a long line of palace revolutionaries of 1725–1825 who wanted to place their candidate on the throne, but many Decembrists also wanted to implement either classical liberalism or a moderate conservatism contrary to the more Jacobin, centralizing program of Pavel Pestel or the pan-Slavic confederation-advocating revolutionaries of the "Society of United Slavs". The majority of Decembrists were not members of illegal organizations similar to the participants of palace revolutions. Some were members of the Union of Prosperity only, sympathetic to an official, pro-governmental fairly conservative program. But their revolt, unlike previous Romanov palace revolutions, has been considered the beginning of a revolutionary movement. The uprising was the first open breach between the government and reformist elements of the Russian nobility, which would subsequently widen.
