Could someone help me with this Abstract? I need an English correction, please

This project proposal aims to analyze the Classical Antiquity of Roma representations and the uses in the didactic compendia of History used in the secondary public schools during the consolidation process of the Second Reign of Brazil. Such analysis, in an original approach, will be led to attempt to make clear the redefinition about some elements of the Classic Old World to school subject of History, whose goals were also focused on the construction and consolidation of a new national identity, put together to the dictates of the Brazilian Imperial State. Using methodological principles based upon Renovated Political History (in which the concepts of Political Culture and Representation make up their central conceptual focal point), we listed as the main documental sources of contemporary age the first textbooks of Ancient History used in Brazil educational system, or better say, the translations of Poirzon’s and Caiz’s French works (Ancient History-1838) and the compendium of De Rozoir and Dumont (Roman History-1840). We think the idea about the teaching of Ancient History in the secondary imperial public schools, officially inaugurated in 1838 with Colégio Pedro II creation in Rio de Janeiro, defined the parameters of historical narrative based on political values which does not only present a long time of chronological limits of the Imperial State of Brazil, but also huge contrasts about national political context from that period and its imperial system of government.

Is it better now the last paragraph?

We think about the idea of Ancient History teaching in public high school in the Empire Age, officially opened in 1838 with the construction of Colégio Pedro II in Rio de Janeiro, defined the parameters of historical narrative based on political values which did not only last a long time of Brazilian Imperial State that overcame its own limit, but also presented large contrasts in regard to national political context from that period and imperial system of government.

thanks a lot!
