Miguel Dantas da Cruz is an assistant researcher at the Institute of Social Sciences - University of Lisbon. He has a Ph.D. in History, specialization in Empires, Colonialism, and Postcolonialism. His principal interests have been converging on the Liberal Revolutions of the early 19th century. Changing identities and ideologic adjustments in the broader Portuguese Atlantic world during this period have been topics of his research agenda for a while. At the same time, his research and teaching duties on the arrival of liberalism and the adaptation of traditional societies to the new political and economic agendas steered his attention to two main topics: the world of the trade guilds and the new ideas of political representation and political action. Petitionary experiences of the early 19th century are at the center of his academic initiatives: publications, conferences, and ongoing projects. Previously he studied the history of international relations at the end of the 18th century, with an emphasis on political and economic issues. He has published several essays and a book on Portuguese neutrality during the Atlantic Revolutions. His research on Portuguese trade with North Atlantic and Mediterranean countries filled an important historiographical gap. During his Ph.D. dissertation, he studied the South Atlantic and the dynamics of the Portuguese Empire in America. He explored the bureaucratic mechanisms of the Empire and the circuits of communication between several institutions of the Portuguese political system, starting with the Overseas Council. The work revisited the network and hierarchy of political powers in the Portuguese Atlantic world, it explored who intervened, and how it intervened, in the governance and defense of the Empire. The investigation was subsequently published in several articles, and essays, as well as in a book entitled An Empire of conflicts. The Overseas Council and the defense of Brazil. During his post-doctoral, he continued to expand his research on the military world. He also explored the dynamics of circulation in the Portuguese Empire, especially soldiers in the mid-17th century. He published several texts that correlate the ideologies of the Empire with the evolution of the Portuguese martial imaginary. He was a fellow in the John Carter Brown Library, where he compared the metropolitan hostile reaction to independencies in the Americas. He was a visiting scholar in several institutions (e.g., Brown University). He is part of several ongoing projects, such as RESISTANCE - Rebellion and Resistance in the Iberian Empires and RITUALS - Public Rituals in the Portuguese Empire. In addition to several publications, conferences, lectures, and communications, both in national and international venues (US, Brazil, England, Italy, and France), he has been an active member of the academic community. He recently co-organized the Conference Petitions in the Age of Atlantic Revolutions (c.1760-c.1840), the proceedings of which will be published by Palgrave in 2022.
