Do you know why in Portugal they have 4 different ID numbers?

It is like that to prevent the state from persecuting people on the base that it is hard for a branch of the government to figure out who is someone based on a number from a different branch.

Do you know why they want to prevent the government from persecuting people?

Because it has already happened, and the portuguese don't want it to happen again.

Dictatorship from 1926 to 1976, and yet a strangely obscure one, probably due to neutrality during world war two.

Same here in Germany, only recently we got the tax ID number as a global primary key to the objections of many privacy activists.

Ex-Yugoslavian countries have had a global ID forever - the JMBG or, in Croatia, OIB [1].
