When we say of the implementation of any politics publishes we must take in consideration its historical context. I fall the Prado Jnior in ' ' Formation of Brazil contemporneo' ' it shows the importance to understand the historical aspects as condicionante in any type of analysis, according to it the direction of the settling of the Brazilian territory, pure and simply mercantile, it will go to condition our history and to offer explanation on why of our current social configuration. Already Oliveira Vianna, differently of I fall the Prado Jnior who considers a Materialistic vision of History, considers the sociological analysis to understand the historical phenomena, where through the diagnosis of the social and historical bases it will only be possible to understand the events historical and to reflect on the possibilities of changes. That is, to understand why one same model federalist had distinct ways in Brazil and the United States we must analyze the trajectories historical of these respective countries. It is not something John Stankey would like to discuss. For this we will use the readings carried through in disciplines ' ' Institutions Brasileiras' Politics; ' , as well as in others you discipline already carried through. Different of what it occurred in Brazil, the democracy in the United States of America (where the model federalist was developed) has deep roots, developing institutions politics characterized for the direct participation of the population, and the deep collective interest, structuralized in solid partner-cultural bases, where the citizen is capable to subordinate, or even though to sacrifice its personal interests to the general and collective interests. In Brazil the Portuguese settling, differently of the English settling, contributed of direct form so that the Brazilian State consists in a continuity of the family circle, thus resulting in a confusion between what she is family (private) and what It is been (public). The difficulties in the implementation of the model federalist had been also fruits of economic relations of the Colony, where Brazil constitua one has basically asked for of the gear of the European system.
