This chapter analyzes the formation and expansion of social spaces for political debate and their impact on the formation of political identities as well as its entanglements with an increasing militarization of society. This chapter studies how the military quarters, the camps, and the campaign regiments transformed themselves into privileged spaces for public debate. During the process of Independence, the military forces engaged more in political debates, and members of these forces expressed their political opinions and affiliations in broadsides, manifestos, and printed proclaims. By bringing these often separated social and political spaces, we seek to analyze the impact and relevance that public opinion had in the processes of independence, paying particular attention to the formation of political identities, the emergence of a new political languages, as well as the diverse discursive strategies that leaders in different regions used to mobilize people militarily or to raise political awareness on soldiers. In this way, this chapter seeks to create original analytical connection between political knowledge and debate, and military mobilization in Latin America during the wars of independence.
