Explanation:

Industrialization hastened the decline of old-style conservatism because it tended to strengthen the commerce-minded middle class and to create a new industrial working class with a diminished allegiance to old institutions. Between 1830 and 1880 liberalism won repeated victories over the conservative establishment in western Europe. Conservatives, like other political groups, had to establish majorities in parliament if they wanted to hold power, and the progressive expansion of the franchise meant that they had to cultivate support from a broad electorate. But their chief source of strength, the rural peasantry, was declining in numbers relative to other social groups and was in any case too small to support an effective national party.
