The conservative turn of 1878/79 refers to a shift in political power towards conservative and right-wing factions in Europe during this period. This shift was characterized by the rise of conservative governments and policies that aimed to maintain traditional social structures and resist liberal and progressive reforms. The conservative turn was often a response to economic instability, social unrest, and fears of radicalism, leading to a period of increased authoritarianism and repression in many countries. This shift had significant implications for the balance of power and the direction of political and social change in Europe during the late 19th century. **
