How did European influences change the celebration of Dida de Los Muertos?

In ancient Europe, pagan celebrations of the dead also took place in the fall, and consisted of bonfires, dancing and feasting. Some of these customs survived even after the rise of the Roman Catholic Church, which (unofficially) adopted them into their celebrations of two minor Catholic holidays, All Saints Day and All Souls Day, celebrated on the first two days of November.
