The election in 1871 was warmly contested. The advanced liberals pressed hard on the conservatives, who resisted further changes desperately. The latter united with the moderate liberals upon Errazuriz as presidential candidate to succeed Perez, and receiving the support of the outgoing administration he was elected. At first the elements who had elected him controlled a majority in congress, but the aggressiveness of the liberals and rival ambitions in the government coalition soon overthrew the reactionary ministry. Errazuriz changed as congress did and soon found himself pushing liberal reforms. The great issue was the amenability of the clergy to the civil tribunals. Though fifteen years previously President Montt had compelled the reinstatement of two church dignitaries deprived of their places by the archbishop, the clergy had nevertheless persisted in their claims. The liberals now insisted on the adoption of a criminal code which would leave no doubt, and amid bitter opposition it was passed. The clericals were further outraged by concessions as to Protestant worship and the obligatory teaching of the Catholic religion in the state colleges. Though the bill establishing civil marriage failed, the anti-clerical movement went so far that the old-line conservatives withdrew in disgust from the alliance which had existed between them and the moderate liberals since the revolt against Montt. Thenceforth the conservative party ceased to be an important factor, and the predominant liberals divided into factions who intrigued among themselves to organise working congressional majorities, which supported ministries and controlled patronage. Political reform went on with increasing momentum. To curb the control of elections which the ministry in power exercised through the local officers who made up the voting lists, minority representation was provided for, but only after the moderates had forced the radicals to a compromise, which exempted presidential and senatorial elections.
