The Liberal–Conservative Fusion (Spanish: Fusión Liberal-Conservadora) was an oligarchic alliance between Chilean liberal (Pipiolos) and conservative (Pelucones) political parties that existed from 1858 to 1874.
Liberals represented the laity (non-clergy) and were in favor of more political liberties and firmer boundaries on presidential powers granted by the Constitution of 1833.
Conservatives started off with the clergy's influence: they had the Church, with an independent function with respect to patronage, and had firm support from the president.
Their coalition united opposition to the authoritarian practices of the government of Manuel Montt and its minister of the Interior, Antonio Varas.
This was called the Liberal Alliance, which gave the new legislative core to the government of Errázuriz Zañartu in 1875.
